Session Initiation Protocol (SIP) — Client Service Offerings Project

Background and Overview

Session Initiation Protocol (SIP) and Open Source for Voice and associated Data applications is fast becoming a priority pursuit for IT organizations to explore and develop their own host of innovative applications and services by using SIP. The attraction to SIP is that telephony becomes another converged application and integrates easily into other applications and services. Basically, SIP enables the opportunity to easily bridge Voice and Data applications and services together to provide a host of collaborative service offerings.

Stanford ITS recognizes that SIP is a powerful influence for the industry’s next generation Voice and associated Multi-Media product development roadmaps. Therefore, Stanford ITS sees great potential and opportunity in establishing Stanford’s own SIP Open Source suite of service offerings with a goal to ultimately identify attractive, fully integrated Voice and Data applications that the Stanford community will want to use. The scope of this discovery-level project will be to identify and pilot select SIP clients within the Stanford University environment and make a recommendation on how to proceed with SIP as a part of the ITS service portfolio. This project will not include a production offering phase, but that may be recommended as a future phase based upon the pilot findings.

Risks of Not Doing Project

  1. With SIP being the telecom industry’s next generation protocol of choice, Stanford will lose momentum in exploring, developing, and leveraging next generation VoIP and Multi-Media technology application and client service offerings.
  2. This effort is key to delivering on the promise of Work Anywhere. Without this effort, IT Services will be unable to deliver services required for Stanford telecommuting and mobility.

Issues, Risks, and Mitigating Factors

Issue/Risk Likeli-hood (HML) Impact (HML) Mitigation
Network Infrastructure Quality of Service (QoS) readiness H H Required to deliver service offerings.
Organizational Risk — Voice and Data Network will not settle current ownership and strategic direction conflict, which will hamper project teamwork. H H SIP Strategy and roadmap needs to be clearly defined prior to project initiation. This may require high-level organizational directive.
