Securing SIP Trunks

SIP Trunks are a simple, cost-effective way for enterprises to adopt VoIP. They are also a stepping stone to eventual adoption ofUnified Communications. After all, once the network is set up to use SIP-based VoIP via a SIP trunk, the infrastructure is already in place to start using IM, real-time video and the wide array of SIP-based applications available now and in the future.

So what’s stopping many enterprises from embracing SIP trunks? By far, what we hear from customers as the top concern is interoperability — how can I be sure that myPBX will interact properly with the SIP trunking service provider? This is followed closely by security — how can communications routed over the public Internet or a managed connection really be secure?

The fact is, with the right measures in place and with the proper planning, SIP trunk deployments can work flawlessly and be more secure than the PSTN. Here’s how:

Address interoperability at the start — Making sure the IP-PBX and ITSP are interoperable will not only smooth the way for an easy deployment, but also solve many security headaches. Opportunities for hackers, spoofers, etc. are easy to come by when there are inconsistencies between these two key components. Leading IP-PBXs and ITSPs are aggressively conducting interoperability testing; make sure your choice of equipment and service providers have demonstrated successful interoperability with one another.

Several leading PBX vendors recommend that a SIP-based edge device be installed for multiple reasons, one of which is to smooth out interoperability issues. The edge device can perform “normalization” functions both for your current environment as well as any future changes you may make, essentially future-proofing your SIP trunk deployments to ensure interoperability down the road.

Further simplifying vendor interoperability, the SIP Forum has developed the SIPconnect Technical Recommendation, a standards-based guideline for SIP trunking between IP PBXs and VoIP service provider networks. As more service providers, PBX vendors and edge device manufacturers adopt this standard, issues with SIP Trunk implementations will be significantly reduced.

Employ security measures — Like any other server in the enterprise network, the IP-PBX should be protected from unauthorized access. Many firewalls today do not adequately protect against attacks on SIP infrastructure so the edge device chosen should enforce rules and policies designed to protect this vital asset. For further protection, SIP based communications can be encrypted to keep the sessions private with no chance of eavesdropping.

Authentication with the service provider — Some IP-PBX equipment can support this natively, while others cannot. A full SIP proxy firewall or other edge device may offer this capability as well, allowing enterprises with non-authenticating IP-PBXs to leverage the benefits of SIP trunking securely.

VoIP - Asterisk Channel Evolution

Starting from meager beginnings over three decade’s ago, VoIP is a technology that is reshaping the telephony industry. A number of factors have provided resistance to the evolution of VoIP and others that have enabled VoIP to flourish.

One of the major limiting factors is the actual media that carries the signal. When voice was first carried over the Internet, the technology of the day was based on 4800 and 9600BPS modems. Based on today’s standards and the demand for QoS, it is understandable why VoIP took so long to evolve.

Large telephony manufacturers also provided significant resistance to VoIP’s evolution. The large manufacturers already controlled the market. Their current equipment based on TDM provided large margins and was very profitable. Moving to VoIP meant changing the infrastructure and that would change the profitability of the telephony manufacturer .

The channel itself also provided significant resistance to VoIP. The telephony manufacturers, resellers or “interconnects” had complete product lines and were making good margins with their sales. There was no need to move to VoIP. The word on the street was that VoIP did not deliver a quality solution.

The manufacturers also protected the margins of the resellers making the resellers loyal to their existing suppliers and resistant to new VoIP suppliers that do not understand channels.

As the interconnects know, they are the sales force for the telephone companies and manufacturers. They are the feet on the street. They are the direct link to the consumer of the telephony services and equipment. Their margins need to be protected through channel controls.

Most VoIP manufacturers do not know the meaning of channels or they are trying to redefine the channel. Unfortunately for them, the VoIP companies that succeed will be the ones that develop a strong channel strategy. Selling to everyone that calls a manufacturer to order is not a channel strategy.

VoIP Enabling Factors

SIP and RTP both have had a major impact on the evolution of VoIP.

During the 1990s, user demand for high speed connections for use with the Internet increased tremendously. This also gave momentum to VoIP. Now users were able to use DSL and cable for the Internet as well as VoIP. More businesses were signing up for affordable T1s providing them the bandwidth necessary to use VoIP. Everything was starting to come together.

Asterisk was a major factor in changing the perception of VoIP. It was also a way to tie the TDM and VoIP worlds together. At first in 2001 and 2002, Asterisk was shown at Open Source shows to Linux and FreeBSD groups. Then it was presented at Internet shows such as TMC’s ITEXPO. As the firstDigium distributor, my company, Cylogistics, has been able to watch Asterisk growth very closely. During the last half of 2004, Asterisk started to take off.

With the dot-com bust, Linux networking resellers were looking for the next gold mine. They soon came to realize that they had found it in telephony and VoIP. Asterisk enabled them to inexpensively deliver telephony to their existing networking customers as well as expand their customer base. Thus, the Linux networking reseller and Asterisk combined to put pressure on the major telephony providers to start moving to VoIP. By the end of 2005, the major telcos committed to moving to VoIP.

The Linux networking channel and Asterisk have had a profound impact on the telephony industry. Linux resellers have been on the VoIP bandwagon from the beginning. As indicated in the chart accompanying this column, the Linux resellers were early adopters. They really had no competition from the traditional telephony reseller until just recently. Even now, the interconnects are using VoIP solutions offered by the major telco providers.

This trend has been easy to monitor. The major manufacturers of traditional telephony equipment sell their products through national distributors. The new VoIP products do not meet the national distributor requirements and the manufacturers have had to find smaller regional distributors or VoIP specialty distributors like Cylogistics. Now that the interconnects are interested in Asterisk and VoIP, they must find suppliers of the emerging VoIP technology. Cylogistics, being one of those suppliers, is now getting a number of calls from the interconnect market segment and is seeing a significant increase in interconnect inquiries.

VoIP is now in full swing. The bandwidth is there. The infrastructure is there. Moreover, the channel is there for those that choose to use it.

VoIP vulnerabilities in Microsoft Communicator

esearchers at VoIPshield Labs have pinpointed a wide range of denial-of-service vulnerabilities in Microsoft Communicator, the unified communications that features business-grade instant messaging , voice, and video tools.

The flaws, rated “high severity,” could cripple VoIP-powered communications on Office Communications Server 2007, Office Communicator and Windows Live Messenger.

The skinny:

• Microsoft Communicator Emoticon: By issuing instant messages to a client which contain a very large number of emoticons it is possible to cause the Microsoft Communicator to become nonresponsive for a certain period of time. During this period of time the phone does not respond to incoming invite messages and can even be forced to go into an offline state, eventually requiring the phone to reregister.
• Microsoft Communicator INVITE Flood: Due to the manner in which sessions and authentication are managed it is possible to cause Microsoft Communicator to open a very large number of sessions resulting in the consumption of huge amounts of memory, potentially resulting in a Denial of Service.
• Microsoft Communicator Real-time Transport Control Protocol Report Block: Using a specially crafted RTCP receiver report packet it is possible cause a Denial of Service (DoS) against Microsoft Communicator, Office Communications Server (OCS) and Windows Live Messenger.

The company said Microsoft has acknowledged the issues.

Global VoIP keeps Eaton connected

Acquire 35 companies in five years, and you will quickly see the need to reduce the cost of communication across your entire organization.

That's what diversified manufacturing firm Eaton came to realize in 2007, when it decided to leverage its AT&T MPLS (Multiprotocol Label Switching) data network for VoIP -- a shift likely to be duplicated more frequently by enterprise-level companies in the years ahead.

Deployed at 220 of Eaton's 450 locations across the globe, the company's VoGAN (voice over global-area network) has saved Eaton nearly $3 million to date, allowing employees to make calls "on-net to on-net" anywhere in the world without charge, says William Blausey, senior vice president and CIO of Eaton.

"On-net to off-net" calls are billable, but the cost per minute goes way down, Blausey adds.

As anyone in IT might guess, integration proved to be the biggest challenge; Blausey and his team not only had to merge voice and data on the same AT&T network foundation, but also needed to integrate with myriad PBX and telephony infrastructures that the had company elected to continue using.

The result: a centralized infrastructure, with all voice and data streaming through two data centers in Cleveland. In other words, a setup for which data network reliability is critical -- a chief factor in Eaton's decision to go with AT&T, Blausey says.

"AT&T has Class of Service on the managed network," allowing Eaton to segment voice and data traffic on its network, Blausey says. VoGAN is designated Class of Service 1, followed by data, which Eaton designates Class of Service 2 through 4. Internet browsing is treated as a lower class of traffic.

By not completely recapitalizing Eaton's telephony environment, Blausey saved considerably on the project, which involved 12 IT staffers for engineering and deploying voice technologies. Eaton added two engineers with strong Avaya and network experience to help integrate its VoGAN with legacy Avaya, Siemens and Nortel systems, which took considerable work.

"We needed to figure out what the right cards were to put in the switches so they could talk to the AT&T network," Blausey says.

The project, which began in January 2007, prioritized sites that used long-distance calling the most in order to provide the quickest and largest return on investment. With nearly 230 offices yet to be transitioned, Blausey estimates that the company has already achieved about 75% of its anticipated cost savings.

Eaton is also now leveraging the VoGAN system as part of its move to unified communications -- a shift that includes voice-to-e-mail, e-mail-to-voice and the ability to talk to e-mail while on a cell phone.

Overall, Eaton's capital investment in communications capabilities has been reduced by 15% as a result of the project -- not bad, given the increased functionality its employees now enjoy.

Thanks to VoGAN, employees worldwide enjoy the same user experience wherever they travel, increasing productivity by reducing learning curves. Moreover, mobile workers now have a single phone number that can be used to contact them anywhere in the world.

Free Webinar: How Smaller Operators, ISPs Can Take Advantage of VoIP

Experts say that Internet telephony is poised to become a widely deployed technology among SMBs, highly profitable for vendors and service providers – yet the professionals behind VoIP systems must collaborate in order for their products to make money.

As TMCnet reported, officials from AudioCodes Ltd. – an Israel-based VoIP product provider with offices throughout the United States – say it’s time for Internet telephony to evolve from a visionary’s idea to a pragmatist’s business success.

More than half of what is now being sold on the market is Voice over IP, as larger cable and Internet service providers are embracing Internet telephony offerings as a way to bolster customer retention and increase revenues.

Bundled VoIP offerings are a large part of why AMI Partners Inc. predicts that SMB hosted VoIP spending will surpass $1.56 billion by 2010. As hosted VoIP companies themselves have told TMCnet, managed services are especially valuable in this slower economy, as they offer lower upfront and maintenance costs, and greater scalability.

As the quality of VoIP calls improves – such as with AudioCodes’ new “HD IP Phones for the Enterprise,” including the 350HD IP Phone Executive HD IP Phone, pictured right – as TMC Group Managing Editor Erik Linask describes in a video interview here, IP telephony solutions are becoming more and more prevalent across SMBs.

Yet in many ways, small and mid-tier operators, rural telecom companies and ISPs are being left out, put off the cost and technical complexity of creating a VoIP solution from scratch.

In two days, a panel of experts from IBM, Broadsoft and AudioCodes are delivering a free Webinar to help small and mid-tier operators learn how to offer VoIP services to customers.

Register here for “Small Operator, Are You Being Left Behind?” The Webinar will be held at 2 p.m. Eastern on Wednesday, Nov. 19.

Moderated by Linask, the Webinar will feature a panel of experts that includes: Alan Percy, director of market development at AudioCodes; Mike Wilkinson, director of European marketing at Broadsoft, and Scott R. Firth, director of telecommunications solutions forIBM systems and technology group.

Fring Trials Ads On Free Mobile Chat/VoIP Application

Fring is trialing something it should have implemented long ago if it ever planned on making money: ads.

Fring is essentially a mobile VoIP / chat service provider that works on the iPhone and any device running Windows Mobile or Symbian, with technology that enables users to make free calls using the Fring service itself, Skype, Live Messenger, Google Talk, and other communication services.

Up until now, the chat functionality was completely ad-free, but now Fring will gradually start rolling out banner display ads, beginning with a small number of randomly selected users.

From the Fring blog:

We wanted to give you the heads-up, as you may soon see small clickable advertising banners in the fring chat window, beneath the chat itself. Clicking the ad will open your browser and take you to the advertiser’s site; you may even find extra special offers, cool promos & other nice surprises behind the click from time to time And, more clicks mean happy advertisers; and happy advertisers mean more resources for us to develop cool new stuff for you to play with in fring!

The beta version of Fring was made publicly available in January 2007, and is now being used by millions of users across the globe. With $10 million in venture funding, the company was bound to come up with a monetization effort for all those users soon. Unlike competitors such as Jajah and Truphone, Fring is committed to keeping the costs of calling as low as possible and will try to make up for that revenue by slapping ads on chat screens.

Ribbit Rolls Out VoIP Developer Platform

Web-based telephone software provider Ribbit on Monday opened up its platform to developers, enterprises, and carriers.

The company, which markets itself as Silicon Valley's first phone company, enables calls to be made and answered across multiple communication networks, devices, and protocols. Most importantly, Ribbit said, it lets developers create Web applications that use voice without having special knowledge of programming communication apps.

The telephony platform already has been integrated into Salesforce .com's CRM software, and Ribbit said developers can use the communications platform to design, test, provision, deploy, monitor, and bill voice-powered Web applications. Developers will be able to freely market and sell their applications, but they will have to pay Ribbit a fee depending on usage.

"Our vision from the start was 'programmable telephony' -- a platform that enables developers around the globe to design, deploy, and monetize the next generation of telecommunication services," Ribbit CEO Ted Griggs said in a statement. "Now, just four months after BT's acquisition of Ribbit, the platform is live, and we are open for business with developers, systems integrators, and yes, other carriers. ... The platform is now open to anyone -- small businesses, large businesses, telecommunications vendors -- that are looking for ways to innovate with next-generation, Web-based services."

The company said it has more than 7,500 developers working with the platform, which is based on the SmartSwitch software that enables voice to move across landlines, mobile phones, and IM applications. To spur further development, the company is launching a $100,000 contest for the best business productivity, media, social network, and next-generation applications.

The company also is implementing a "Bring Your Own Network" program, which enables other carriers to use the Ribbit software for applications on their own voice networks. This move is part of BT's larger strategy to evolve from a traditional telecom into more of a software-focused telecom, Ribbit said.

In addition to Ribbit, InformationWeek has evaluated three hosted IP PBX systems, which offer small and midsize businesses all the benefits of voice-over-IP services without the cost of buying and maintaining their own switches.

Security tool for VoIP solutions released

A new tool which allows administrators to assess if their VoIP solutions are vulnerable has been released.

UCSniff, from Sipera Systems' VIPER Lab, is a free application which is designed to allow network managers find out whether their VoIP solutions can be eavesdropped on.

It allows them to find out how easy it is to imitate an enterprise VoIP phone, download a directory and then listen in on confidential calls.

"UCSniff is an assessment tool that helps demonstrate vulnerabilities in VoIP design and implementation," said VIPER Lab director Jason Ostrom.

"It was born from the concept of combining targeted attacks against VoIP users along with the corporate directory, intelligent VLAN support, and man-in-the-middle features."

The results of a survey released last month revealed that security was one of the top-five concerns for respondents when investing in VoIP solutions.

Performance, hardware reliability, cost and technical support completed the top five in the fifth annual Enterprise VoIP Survey, by IDC and InfoWorld magazine.

VoIP, UC network planning and management the focus at VoiceCon 2008

VoiceCon San Francisco 2008 opens this week with a flurry of product announcements and demonstrations, so in this week's newsletters we'd like to highlight a few news items that were released in advance of the show. Today, we'll focus on tools designed to improve VoIP and unified communications network planning and management from Mindsharp, NetIQ, NetQoS, and Psytechnics.

Mindsharp, a global education company that specializes in Microsoft enterprise products will be on hand at VoiceCon to discuss its 16-module, five-day comprehensive instructional program available for Microsoft Office Communications Server 2007 core components. The primary target audience for the course is “OCS administrators who intend to design, implement, and manage OCS 2007 as either a stand-alone implementation or as part of a larger unified communications strategy,” according to the company.

NetIQ, a provider in systems and security management, will showcase its latest release of Vivinet Diagnostics, an analysis tool designed to diagnose and troubleshoot voice quality issues. The latest features add “Layer 2 and 3 path tracing across VLAN configurations and deeper support for Nortel hybridized Ethernet, router and switch data gear,” according to the company’s pre-show disclosure.

NetQoS, a company that specializes in network performance management software and services is launching its latest tools for VoIP monitoring that will expand support for unified communications and provide video quality monitoring. The release also adds “enhanced diagnostics and reporting for Cisco IP telephony environments,” according to the company.

Psytechnics, a voice and video performance management supplier for telecom operators and enterprises will unveil its Experience Manager 4.0. The tool is designed to manage and diagnose video conferencing and voice issues.

Our observations: First, we should point out that management tools aren’t the only thing going on at VoiceCon - we’ll highlight other product announcements next time. But we’re encouraged to see a wide variety of alternatives that help network managers address everything from human factors (with Mindsharp) to unified communications and video performance management across multiple platforms because performance management continues to be a hot button issue for successful deployments. And we encourage enterprise IT managers to intelligently compare the available selection of these tools, deploying those that will best help them sleep a little better at night.

VoIP Phone Calls: Changing the Way of Inquiring People Around Us

The ability to transfer human voice into signals of digital nature and then sending them across networks in the form of data packets have led to the wonderful occurrence of VoIP calls all over the world with human beings reaping the advantages of this technology to its full potential.

Business dimensions of this technology have been understood and hence, the world now sees the emergence of VoIP service providers in large numbers in different countries and giving the customers are now being vested with advanced means to talk.

The primary reason for people preferring to make VoIP Phone calls http://www.youtring.com/mobile-calls.aspx is its price which has the primary feature of being quite cheap. Hence the inclination will always shift towards the VoIP phone service due to the chance of having to pay less by a mammoth degree when compared to the costs incurred while making local or international calls with the help of the normal telephone.

The features of this new technology are quite advanced enough to provide many useful features to the persons using it and the process of VoIP calling is now one, which is gaining an increasing degree of realism with large number of human beings making VoIP calls for staying in touch with their friends and relatives.

The process of making VoIP calls can be done with the help of a standard telephone. This is possible due to the fact that all the telephone requires for being able to handle the process of VoIP calling is an ATA or an Analogue Telephone Adaptor. He can also make calls with the help of VoIP phones which already have the necessary technology and hence both time and money is saved by not having to make the required installation in the case of a standard telephone.

The website has become a major tool for many businesses and is also giving its advantages to the service providers who give this technology of VoIP. The user is also able to do many wonderful things in order to find the most beneficial service for him. With business being the major drive behind the service of VoIP, hence innovations are constantly being made in this technology and all these are being made available to the common public in the form of different types of offers. The features of these offers are not only the basic feature of VoIP calling either with the help of a VoIP phone or a standard telephone attached with an ATA(Analogue Telephone Adaptor), but the user is also given a host of other services as well. Hence the user who wants to take the advantages which are associated with making VoIP calls http://www.youtring.com/mobile-calls.aspx , get many extra benefits and features. All these offers therefore, are available on the websites of all the service providers who are operating and hence, the user can compare the benefits given by these offers and select the one which serves his needs in the best possible way.

The VoIP phone service is thus proving to be a new facility for human beings and for businesses too with the ability to give low priced calls for international locations or national locations or even the wonderful prospect of absolutely free VoIP calls as well. The scenario of the communication features are now changed with the emergence of the process of VoIP calling and the future is quite an hallowed one as every technology is bound to see advancements and therefore, improved facilities.

South Korea introduces number portability to encourage VoIP

Charice Wang South Korea introduces number portability to encourage VoIP The Korean Communications Commission (KCC) introduced VoIP number portability between PSTN and VoIP service providers at the end of October. It allows fixed line users to switch to VoIP-based packages from alternative operators while retaining their fixed line number. This move will encourage take-up of VoIP in Korea.

Number portability changes the regulatory scene in Korea

Korea is known for its unique regulation of VoIP.
It is the only country so far to impose interconnection price control on facility-based VoIP operators. This is different to most European regulators, who have taken a 'wait-and-see' approach to VoIP interconnection regulation. The VoIP termination rate is W5.5 ($0.004) per minute, and VoIP operators pay W18 ($0.014) per minute for outgoing calls to PSTN.
However, this wholesale tariff regulation has had a limited effect on the development of VoIP. Currently 14 VoIP service providers (nine operators and five value-added service providers) are competing in the market of around 900,000 subscribers. This is relatively limited growth of VoIP in comparison to Japan (15 million as of 2Q07), given the similar situation of advanced broadband infrastructure and penetration.
The incumbent KT has taken a strong defensive stance on VoIP. KT currently dominates more than 90% of the fixed-line market. Hence it set the VoIP-to-fixed and VoIP-to-VoIP call retail tariff at around the same price as KT PSTN local calls. The cheap legacy telephone service prices and absence of number portability meant that VoIP providers have failed to disrupt the fixed market. It is therefore no surprise that the KCC decided to review the VoIP regulatory framework this year and proposed number portability.
Number portability will speed up the growth of VoIP services With the introduction of number portability, VoIP will experience a higher level of uptake and will soon become a mainstream service. The number portability will allow alternative operators to strengthen their competitiveness against incumbent KT by offering cheaper call options. These operators, such as SK Broadband (previously Hanaro Telecom) and LG Dacom, will see number portability as a strong opportunity. For incumbent KT, it is time for it to change its defensive strategies on VoIP; it should try to take the initiative in the VoIP market to protect its broadband subscriber base. Fixed line competition in Korea is set to heat up.

Choose a security-aware VoIP provider for conferencing

A major advantage of VoIP is that it allows employees to take part in meetings regardless of their location, but a security-aware VoIP provider should be chosen to deploy the system, an industry commentator has said.

Michelle Robart, from TMCnet, explained that VoIP solutions can let a number of users be connected on one conference bridge.

People working from home or other locations can enter the meetings via their telephone, computer or softphone using a process called IP audio conferencing.

She explained: "IP audio conferencing relies on packet switching to transmit data from one point to another."

However, she warned: "Those in the market for a business VoIP service should be aware that every audio-conferencing solution does not offer security options to protect against network intruders."

She recommends looking for a VoIP provider that has multilayered security systems in place to protect its IP infrastructure.

Ms Robart also advised businesses which want to purchase an IP audio conferencing system to be aware of the H.323 standard, which defines how information is sent over IP networks.

'Rapid cost-savings driving VoIP take-up'

Many businesses might be tightening their belts financially amid the economic downturn, but that does not mean investments in IT communications technologies are being pinched.

On the contrary, recent research has suggested that the credit crunch has merely prompted smaller firms to invest in IT solutions which can streamline communication options while also cutting costs and improving flexibility, by enabling telecommuting, reduced travel and virtual networking.

VoIP, which enables voice calls over an internet connection, is one of the IT solutions at the forefront of business' minds, it appears.

New research by Conjungo has revealed that VoIP is the most searched for single item on its UK IT channel.

The firm, which provides an archive of more than 15,000 IT technology suppliers, analysed the activities of website visitors in October and found that a tenth of all searches related to VoIP and IP telephony.

According to David Cruse, chief executive of Conjungo, ten per cent of users interested in just one area of the website's array of searchable online content constitutes a "huge" proportion.

He said: "We believe this is an indication of the potential for rapid cost savings that VoIP technology offers combined with a need for truly independent advice for small business on how to find and implement the best solution and supplier."

Indeed, VoIP's potential cost-savings have already been well documented in the US. Point Topic research last month showed that VoIP and related security services accounted for more than half (56 per cent) of the worldwide broadband value-added services market, which was predicted to be worth some $25.7 billion (£15.7 billion).

US-based VoIP provider Bandwidth.com recently said that smaller businesses in the US have already saved more than 50 per cent on their telephony costs through VoIP.

A further attraction of VoIP is its simplicity. A router, special phone, or standard phone with an adaptor box is all that is needed to get your business up and running, according to Dr Adam Le Gresley, head of operations at business and communications technology advisory group Technology Means Business.

He said recently: "Whether you have a physical work space, whether you're working from home or if it's a virtual organisation, you can have everything linked up to a relatively cheap voice-over-internet system."

Companies looking to improve communications between their branch locations, offices and with their supplies have driven the growth of the enterprise VoIP market, concluded Research and Markets' Enterprise Network Equipment & Network Management Services Market 2007-2010 Bundled Report.

It added that enterprise VoIP is also developing further trends in hosted solutions, internet security and networking equipment as firms are upgrading their IT technology so it is compatible with new technological developments for the next five to ten years.

Amid the ramifications of the credit crunch, the report also said: "Cost savings and robust feature sets are also expected to drive increased spending on IP telephony equipment."

So thanks to its proven cost savings and compatibility with emerging IT business trends, VoIP is well-placed at the front of a new wave of solutions - including hosted services, cloud computing, virtualisation and wide area networking - that continue to attract firms closer towards an e-business model of enterprise operations.The 8el CallPort is and IP Centrex solution developed as an alternative to a LAN based PBX. CallPort is differentiated from any other IP Centrex platform and has been designed to deliver a range of telephony features and benefits to the mid-enterprise market space.Says Justin Hamilton-Martin, Managing Director of 8el "While there are many VoIP offerings out there, no one is doing this in the same way as 8el: we are the only service of this kind, with the level of functionality and resilience that we are able to provide. It is suited to any company that wants to maintain control over their communications, while experiencing the benefits of VoIP, but without having to employ dedicated staff or make large investments in equipment."

VoIP vs dino technology

Cape Town - Voice over Internet Protocol (VoIP) solutions address the shortcomings inherent in the premicell or least cost routing (LCR) solutions, such as the lack of Caller-ID information on outgoing calls and the long contracts companies need to sign with service providers.

That's according to Greg Massel, managing director at Switch Telecom, a telecom company that operates an advanced VoIP and switched network.

He says that many enterprises that have been using premicell (a type of cellphone device that gets attached to your switchboard) to reduce their telephone bills, should be looking at moving across to VoIP-based solutions instead since they offer a range of functional benefits, in addition to the cost-savings.

One problem that many enterprises experience with premicells is that they generally block the sending of Caller ID information.

Consistent caller ID

Even when configured to send Caller ID, the multiple different numbers associated with each premicell are difficult to recognise. That means many of the people you are dialling will not answer their phones.

With VoIP, a consistent and recognisable Caller ID is displayed on the recipient's phone so that they know who is calling.

The result: you get in contact with more people on the first attempt, and without annoying them, saving you time and money, said Massel.

Another benefit of VoIP is that it is available on a month-by-month contract with no minimum call spend commitment.

By contrast, premicells are subject to 24-month contracts which means that one could be stuck paying for unneeded minutes if the company's call volumes dip.

Savings on all phone calls

Alternatively, if call volumes are increasing, one will need to constantly add capacity and refresh the contracts.

VoIP allows companies to achieve savings on all phone calls to fixed-line numbers as well as cellphone calls and even calls to special numbers, while premicell offerings address only cellphone calls.

While premicell technologies do deliver cost reductions on cellphone calls, the savings are almost always less than anticipated and come at the expense of 24 month contracts and difficulties connecting calls at peak call times, said Massel.

One problem with premicells is that each device and contract can carry only one call at a time, meaning that if two or more people in the organisation try to dial a cellphone number at the same time, only the first call will be routed through the premicell at a discounted rate.

Multiple calls

Although multiple premicells can be installed, companies need to strike a careful balance between having too few devices and contracts to cater for the volume of calls to cellphones and having too many, which means that they will not use all the minutes they pay for, Massel said.

"VoIP, by contrast, can handle multiple calls simultaneously. On the surface, savings on call rates to South African cellphones may not appear as impressive as those promised by premicells, but in reality, they usually add up to more since savings apply to every single cellphone call made from the switchboard," Massel added.

"In a nutshell, VoIP offers you savings on call types and across your entire call volume and without getting tied into a long-term contract.

"You don't need to worry about managing call volumes since a VoIP solution scales alongside your business," said Massel.

In addition, all calls are routed via direct interconnects resulting in superior call quality, faster connection times, and guaranteed delivery of Caller ID.

VoIP is a compelling and affordable solution for any company that is looking to save money on its monthly phone bill.
