Where is defined SIP 1.0? maybe you mean RFC 2543 (also SIP 2.0) ? :) > That's often a reason why we have to send one thing, but accept other > syntaxes as well. At least RFC 2543 states the same: http://tools.ietf.org/html/rfc2543#section-4.3.1 4.3.1 SIP Version Both request and response messages include the version of SIP in use, and follow [H3.1] (with HTTP replaced by SIP, and HTTP/1.1 replaced by SIP/2.0) regarding version ordering, compliance requirements, and upgrading of version numbers. To be compliant with this specification, applications sending SIP messages MUST include a SIP- Version of "SIP/2.0". -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
