Public SIP Interoperability Event »International SIP 2004«

Public SIP Interoperability Event »International SIP 2004«

Goals Combination of private hotstaging and public interoperability demonstration The private event improves SIP interoperability capabilities of the evaluated devices. The public event showcases the solution to conference visitors and confirms that participant is efficiently addressing SIP interoperability issues.

MSF Collaboration “A number of service providers have recently announced SIP-based voice over IP services, and many more are about to follow. This showcase highlights the forum’s goal to advance the SIP technology as part of an open multiservice architecture.” Roger Ward, President

SIP Forum Collaboration “This public multi-vendor showcase complements the private SIP Forum test events and is very important for us to demonstrate the advancement of the SIP technology to network operators in Europe”. Jay Batson, Chairman

Testplan Design Participants and EANTC created an individual test plan for the hotstaging, based on: MSF Implementation Agreements SIP Forum test suites EANTC service provider test experience. Test plan Participan ts

Public Show Case Here at the conference, just opposite this room

Conclusion I advance public SIP multi-vendor interoperability demonstrations to the next level proved that SIP is a mature technology in many areas and is ready for deployment in a larger scale industry forums involved have proactively created necessary documents and tools to improve multivendor interoperability wealth options in SIP standards, ongoing standardization work and vaguely defined operator requirements may lead to interoperability issues continue interoperability and security verification regularly

Conclusion II Future interoperability events focusing carrier infrastructure will need to evaluate scalability issues, specifically for media gateways While most of the deployed SIP networks are homogeneous right now — and thus not affected by interoperability issues — the power of SIP technology in service provider environments will increase with the number of vendors committed to interoperability of common feature sets
