Mission
The SIP Forum performs a variety of activities to accomplish its mission.- Technical activities. While the IETF is the body that establishes the core SIP protocol definitions in Internet standardInternet standardIn computer network engineering, an Internet Standard is a normative specification of a technology or methodology applicable to the Internet. Internet Standards are created and published by the Internet Engineering Task Force .-Overview:...
documents (RFCs), the SIP Forum performs ancillary technical activities.- SIPit events.http://www.sipforum.org/content/view/29/184/ Previously called Bake-offs, these events are held at least two times a year in various venues around the world. Vendors of products and services that implement and use SIP send engineers and products to the event, and all participants spend a week making their products interoperate with each other. These events have been held since 1998, and have been one of the single most important industry events to help further standards-compliant products. The SipXSipXsipXecs is an open source voice over IP telephony server. Its main feature is a software implementation of the Session Initiation Protocol , which makes it an IP based communications system . Featurewise, it is not unlike Asterisk, a very popular open source PBX, but the design of sipXecs deviates...
ECS system serves as a reference implementation for the SIP standard. - SIMPLEt events. These are like SIPit events, but are held specifically to test the interoperability of products that implement the instant messaging and presence components of SIP.
- Technical working group Recommendations.http://www.sipforum.org/content/view/28/139/ While the IETF standardizes SIP and ancillary protocols, the IETF is not the right organization to create documents with the force of standards, but which are application-level and use-level documents. The SIP Forum works with the IETF to determine which of these are best handled outside the IETF, and the Forum acts as the technical body to create such Recommendations. (The Forum's process mirrors that of the IETF.)

- Marketing activities. The SIP Forum maintains a website and a Wiki devoted to providing information about SIP, primarily to a technical audience. It also sponsors booths in relevant trade shows, and does other marketing to advance the adoption and use of SIP.
Members
The SIP Forum has two types of members:- Participant Members. Any interested individual can become a Participant Member at no cost simply by signing up at the Forum website. This allows users to participate in email discussions and other online activities. As of mid-2005, the Forum has over 4,000 Participant Members.
- Full members. Organizations can pay €5000 per year to become a Full Member. Primarily, this gives the Full Member the ability to vote for Forum Board of Director members (as well as list its logo on the Forum page.) As of mid-2005, the Forum has 53 Full Members.
