Projects 

SIP Performance Benchmarks: Methodology, Terminology for finding the "performance knee" of a SIP Proxy instance. Draft at IETF BMWG. Test tool conformant with the drafts.

NG9-1-1: NENA Industry Collaboration Events: Collaboration with the National Emergency Numbers Association to support interoperability of functional elements of the NG9-1-1 architecture. Maintainance and growth of three Emergency Services IP backbone networks on the two IIT campuses.

Network Transport and Performance Testbed: STUN and TURN servers as well as SIP servers and WebRTC-enabled Web Servers are deployed in various configurations of this test bed whose nine domains and sub-domains can be used to test the behavior of Web-RTC-based and SIP-based applications as they traverse the domains with the help of the STUN and TURN services.

Voice over IIT: This on-going lab project is a working SIP-based IP-Telephony system using Kamailio ad Asterisk servers and connected to the PSTN by a SIP Trunk.
