Veraz Networks Intros New SIP Gateway; Discusses its Benefits

By Michelle Robart, TMCnet Editor

Veraz Networks, a provider of Multimedia Generation Network application, control, and bandwidth optimization products, today announced its latest media gateway solution, the I-Gate 4000 EDGE SIP Gateway (News - Alert) (GW).
This new SIP Gateway allows for seamlessly integration with existing PBX (News - Alert) and PSTN switches, thus enabling service providers to offer competitive services at an affordable cost without replacing their current equipment.
It also provides high voice compression while maintaining toll quality, significantly reducing bandwidth and routing resource expenses while the redundant architecture and high processing capacity delivers high reliability.
Gus Elmer, Corporate Marketing, Veraz Networks discusses this latest product release with Technology Marketing Corporation, explains its benefits and how it will change the VoIP landscape for many businesses.

TMCnet: What are some of the creative, real-world applications you’re seeing customers using VoIP for?
GE: VoIP technology is now becoming embedded in a wide array of applications well beyond person-to-person calling. Veraz expects VoIP to become standard on mobile handsets in the relatively near future and become increasingly a common capability on the Web. Gaming and dating services are two examples of Internet-based services in which VoIP has become embedded as a natural extension of the service.
TMCnet: What do you think is the main reason VoIP is gaining popularity among businesses for internal use?
GE: We see two fundamental drivers for enterprise VoIP adoption. The first is significantly lower cost relative to their existing legacy voice infrastructure. The second is the potential offered by VoIP for integration of voice calling with IT infrastructure to enable unified communications.
TMCnet: Why are most businesses continuing to rely on existing enterprise TDM equipment for voice services beyond the building?
GE: The initial focus for most business VoIP projects was focused on cost reduction through removal of legacy PBXs and integration of voice with IT infrastructure. Much of the benefits for these initiatives could be achieved without changing their voice services beyond the building. In almost every case, businesses continue to need connectivity to the PSTN and the easiest way to get that was through legacy (e.g. TDM) infrastructure.
We expect to see increasing demand though for SIP trunking as enterprises expand beyond the IP PBX look to leverage new SIP-based carrier services. At the same time, for many, the existing PBX works fine and SIP gateway products like the I-Gate 4000 EDGE SIP Gateway allow them to take advantage of lower cost SIP services without forklift upgrades of their internal network.
TMCnet: How does extending PBX functionality to remote locations using only IP gear save monthly expenses and infrastructure costs for companies?
GE: SIP Gateways like the I-GATE 4000 EDGE SIP Gateway enable remote sites to use lower cost IP phone solutions and tie them into rest of the enterprise through IP. The alternative is to use more expensive legacy TDM equipment and interconnect services. SIP Gateways therefore save enterprise customers money by both reducing their capital requirements within the building and reducing their monthly network services expenses.
TMCnet: Explain Veraz Networks’ new SIP Gateway for VoIP applications. What does it do and how will users benefit?
GE: The I-Gate 4000 EDGE SIP Gateway is a compact, feature-rich SIP gateway designed to interconnect TDM networks with SIP/IP for voice, fax and data services. While more and more businesses adopt VoIP technology internally, most businesses continue to rely on the large embedded base of enterprise TDM equipment for voice services. SIP PRI gateways like the I-Gate 4000 EDGE SIP gateway allow service providers to reduce the cost to provide service to these customers as well as cost effectively reach new customers through IP instead of costly TDM infrastructure. In addition, SIP PRI gateways enable enterprise customers to extend their PBX functionality to remote locations using IP without deploying additional TDM/PBX infrastructure.
The I-Gate 4000’s key differentiators include:
Six 9’s reliability to ensure high availability. No other comparable product supports full system redundancy which means their availability figures will be below five 9s. High reliability is especially important because this product will typically be placed on the customer premises and not a service provider building which means getting access to it in the event of a failure may be difficult and time-consuming.

30 – 50 percent reduction in size for the same maximum traffic load. The I-Gate 4000 EDGE SIP Gateway provides sustained high call-handling performance independent of traffic load. Other products of similar size and capacity cannot support their claimed maximum performance (e.g. call setups per second) when close to their maximum capacity (e.g. simultaneous calls).

Easy to use and comprehensive digital handling and call routing features. Relative to competitive products, the I-Gate 4000 EDGE SIP GW configuration process is straightforward for the operator. In addition, it supports a comprehensive set of digit handling and call routing capabilities.

Demonstrated multi-vendor interoperability. We have already demonstrated live interoperability with a widely deployed 3rd party softswitch and expect based on our experience with media gateways that the I-Gate 4000 EDGE SIP GW will be easy to interwork with other vendors products.

Industry-leading compression with toll-quality voice. The I-Gate 4000 EDGE SIP GW leverages the compression technology behind the I-Gate 4000 media gateway family to provide industry leading compression levels without sacrificing voice quality.
TMCnet: Where do you see VoIP technology in the next 10 years?
GE: Over the next 10 years, Veraz believes that VoIP will become the dominant way for people to connect and talk.
