The SIP Forum SIPit(SIP Interoperability Test) is the premier international test event for real-time IP communication using the Session Initiation Protocol. Twice a year, around one hundred companies engage at the SIPit for a week of testing to refine both the specification and implementation of the world's next communication infrastructure.

The purpose of the SIPit event - SIP interoperability test event - is to test for interoperability of SIP implementations, to determine the source of incompatibilities and if necessary to prepare a revision of the specification.

This event is open only to implementers with working SIP implementations. It is not a trade show, public demonstration, conference or workshop.

The individual results of the event are kept confidential.
By participating in this testing event, you agree not to separately disclose, comment on, or otherwise characterize the results of the testing event, or the operation of any individual vendor's equipment.
