SIP Is Interoperable 2 Successful Bake-offs

15 companies

Began with basic call set up (2 Vendors)

Elevated testing to more advanced features such as; authenticated registrations, multi-hop proxy and media transport

Communication Between Endpoints Two vendor demo - PingTel

Moving Forward with Interop Testing Bake-off needs to focus on three-way testing between vendors to better

model the needs of a commercial network

Documented SIP Performance Exists Ability to scale to 500,000 BHCA

Moving Forward with Scalability Develop performance benchmark

Continued SIP performance from multiple vendors to eliminate any speculation that SIP is ready for deployment NOW

SIP is Extendable SIP-T - SIP for Telephony Interworking

SIP for intra-softswitch communications

Allows for the bridging of the PSTN and IP networks

CPL - Call Processing Language Network edge service creation

Allows for the Proxy Server to handle service requests

DCS - Distributed Call State SIP for cable telephony

Allows for service intelligence to be decentralized
