Until September 1999, discussion about SIP took place on the MMUSIC mailing list. The working group and mailing list is still the appropriate place for discussions related to SDP, SAP and RTSP, among other topics.

SIP standardization has now moved to the SIP working group, with its own mailing list. The SIP Forum at http://www.sipforum.org also provides information about SIP.
