Public SIP Interoperability Event

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.

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 forums goal to advance the SIP
  technology as part of an open multiservice
  architecture.

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.

Public Show Case

• Here at the conference, just opposite this room

14
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
  multi-vendor 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

15
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
