Helping the SIP Forum Accomplish Its Mission

The SIP Forum is a non-profit organization dedicated to the adoption of SIP and promotion of interoperable product and service implementations. Our principal activities include:

• Organizing SIPit and SIMPLEt interoperability test events;
• Organizing and providing a forum for our various Working Groups to accomplish the mission of the Forum;
• Creating Recommendations (mostly technical) to guide implementers on how to implement SIP functionality in ways to insure high-interoperability for functions not defined by other standards bodies (such as the IETF);
• Act as an authoritative voice to the industry on SIP-related matters, through speaking engagements, and other personal activities by our leadership and membership, as well as this website.

By joining as a Full member, your primary benefit is the assurance that these important functions will continue to be accomplished for the benefit of our industry.

To do so, we rely on the generosity of organizations to become Full Members and pay their dues to help us pay our extremely modest annual operating costs. (Our operating budget is small - around €250,000/year.)
