A webinar, entitled “Making VoIP Secure, Efficient and Seamless Across Enterprise and Service Provider Networks,” will be held March 29, at 11 a.m. EST and 8 a.m. PST, and 4 p.m. in London, England.

Today’s VoIP networks, Webinar officials say, “are gradually superseding circuit-switched networks in meeting the communication needs of enterprises and service providers. A wide range of hybrid networks is emerging that require interoperability of IP-based and circuit-switched network components.”

As the presentation will discuss, this may result in complex network interconnections at the network edge. The advent of all-IP communications creates a fresh set of needs in this environment.

Presenting is James Rafferty, product line director for Integrated Media Gateways at Dialogic (News - Alert). In this role, he is responsible for VoIP Gateway products sold to carriers and related market strategies.

The webinar includes an overview of the changing network edge and shows how media gateways are evolving and incorporating session border control functions: “A new generation of SBCs and Border Elements that integrate signaling, transcoding and security functions can be used to reduce cost, introduce network flexibility and enable new communication capabilities for voice and other media.”

Among other topics, the presentation will discuss how enterprise and service provider networks are evolving and connecting to support VoIP, why media gateways are evolving to support hybrid and pure-IP networks in the same product, how media gateways, border elements and session border controllers can share duties to reduce overall network costs, how new IP communication scenarios are enabled between enterprises and service providers and how to reduce CAPEX and OPEX (News - Alert) costs when implementing a hybrid network transition strategy.

Rafferty has managed a variety of VoIP, SS7 and voice products as a senior product manager for Cantata and Brooktrout (News - Alert) Technology. Previously, he was president of Human Communications, a leading technology consulting firm for telecommunications companies. He was also one of the pioneers for computer based fax and related standards when working for Fujitsu Imaging Systems (News - Alert) in a variety of R&D and Product Line Management roles.
