Nortel/SIPcomm/Columbia co-operation in IP Telephony Henning Schulzrinne (Columbia University) Joe Flicek (SIPcomm)
Columbia/SIPcomm Technology • Complete SIP-enabled communications infrastructure: • SIP proxy server for call routing, programmable services using cgi, Java servlets and CPL (XML-based call processing language) • SIP conferencing server for large conferences (up to 100 participants) • SIP unified messaging server • SIP-to-H.323 gateway • SIP user agent (Windows, Linux, …), including instant messaging, events and presence
Scope of Project • Seamlessly integrate SIP-based open IP telephony infrastructure with Nortel Meridian PBX • Several alternatives: • (1) Add SIP to Nortel Ethernet board • (2) Stimulus-to-SIP translator, making SIP terminals appear like I2004 terminals • (3) Integrate with any Nortel SIP-based linecards
Value to Nortel • Add new capabilities to existing and new Meridian installations • Programmable features -> integration with corporate databases, calendars, off-site phones • More cost-effective incremental transition for installed base • New services, e.g., integration with presence/IM
Resources Needed • Resources depend on project variant: • (1) Development environment for board • (2) I2004 phones and protocol description • (3) Access to Nortel Meridian expertise and possibly a PRI/Ethernet interface (for CLID) • Student support ($50k/year/student) • SIPcomm developer support
