SIP-enabled products grab spotlight

FRAMINGHAM (09/26/2003) - Session Initiation Protocol was on the minds of vendors introducing products at this week's Voice on the Net conference in Boston. Nortel Networks Corp. introduced software that works with its Multimedia Communications' Server 5100 and 5200 designed to help companies build applications that combine voice, video and instant messaging. The servers are IP- and SIP-based phone switches for enterprise and carrier networks.

The company's Media Application Server software could support an application such as a handheld-based client that uses presence features to set up an IP conference based on voice, video, instant messaging or a mix, Nortel said. The software runs on a Windows-based IBM Corp. X335 Server, starting at about US$700 per client.

Separately, Spectel Inc. announced its Open IP-Enabled Conferencing suite of applications, based on SIP. Spectel said the product lets service providers offer lower-cost IP-based multimedia conferencing and presence management services to customers. The company said the software also can be deployed with SIP-based IP PBXs or IP-enabled PBXs, from companies such as Avaya, for deploying IP conferencing applications as an alternative to public switched telephone network conferencing inside large companies. Pricing was not released.

On the security front, InGate Systems AB aired its SIParator 20 appliance. The box, which supports 10 to 400 users, would sit at the edge of an enterprise network in front of a firewall and process SIP traffic that would otherwise be blocked. InGate says its box could help businesses secure SIP-based conferencing applications without opening holes in a corporate firewall.
