2. 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

4. 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

5. 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

6. 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
