Public SIP Interoperability Event »International SIP 2004«

1. Public SIP Interoperability Event • »International SIP 2004«

2. Goals • Combination of private hotstaging and public interoperability demonstration • The private event improvesSIP interoperability capabilitiesof the evaluated devices. • The public event showcasesthe solution to conference visitorsand confirms that participant isefficiently addressing SIPinteroperability issues.

3. 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

4. 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

5. 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 Participants

6. Reference Documents • MSF-IA-SIP.001-FINAL, Implementation Agreement for SIP Profile, for Voice over IP, betweena line-side Media Gateway Controller and a Trunks Media Gateway Controller. • SIP: Session Initiation Protocol, RFC 3261 • STUN - Simple Traversal of User Datagram Protocol (UDP) Through Network AddressTranslators (NATs), RFC 3489 • Session Initiation Protocol (SIP) Basic Call Flow Examples, RFC 3665 • draft-ietf-sipping-service-examples-05.txt • draft-ietf-sipping-torture-tests-02.txt • PROTOS Test-Suite: c07-sip

7. Testplan Contents • Infrastructure and Scalability Tests • SIP-to-SIP Calls: One Proxy and Proxy Chaining • Calls via a Firewall with NAT and STUN • SIP-to-PSTN Calls • Services and Applications Tests • Unattended Call Transfer and Unconditional Call Forwarding • Codec Negotiation • Security and Robustness Tests • Digest Proxy Authentication • Robustness Tests

8. Private Hotstaging • Prior to the public show case in January 2004 • Took place at EANTC in Berlin, Germany • Four days of in-depth,any-to-any testing • Result: Internal test reportunder NDAcompiled by EANTC • Public documentation:White paper

11. Evaluation Results I

12. Evaluation Results II

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

14. Conclusion I • advance public SIP multi-vendor interoperabilitydemonstrations to the nextlevel • proved that SIP is a mature technology in many areas and is ready for deployment in a largerscale • industry forums involved have proactively created necessary documents and tools to improve multi-vendor interoperability • wealth options in SIP standards, ongoing standardization work and vaguelydefined operator requirements may lead to interoperability issues • continue interoperability and security verification regularly

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