SIP Trunking a Hot Topic at VoiceCon

“Among the best-attended sessions on the first day of VoiceCon 2010, in San Francisco [sic], was one entitled ‘SIP Trunking: Who’s Offering What.’ The panel featured speakers from AT&T Inc. (T), Sprint Nextel Corp. (S), Verizon Communications Inc. (VZ) and Global Crossing Ltd. (GLBC), and it offered an overview of what has become one of the most important areas of focus for enterprise IT and communications directors, and the vendors and carriers who serve them,” writes Richard Martin on

“Heading into the show, Verizon Business said that it has been named a Microsoft SIP Trunking partner, meaning that the carrier’s SIP trunking offering, called Verizon IP Trunking, has been certified for the latest version of Microsoft’s Office Communications Server. Verizon thus becomes the latest carrier to release a comprehensive SIP-trunking product to support UC applications across far-flung and heterogeneous networks.”

“Smaller vendors are also hastening to release SIP trunking products: Grandstream Networks, a supplier of IP voice/video telephony equipment, said today that its IP PBX, known as the GXE502x series, and its gateways, are now interoperable with Skype for SIP, offering sizeable cost savings for outbound calls via Skype,” Martin writes.
