Hi, I'm doing college work on SIP and reading RFC2543 and the book "Understanding the Session Initiation Protocol" (Alan B. Johnston). On page 56 it lists the Contact header field of an INVITE Request as being mandatory but this doesn't seem to be the case according to the RFC. Could anyone please confirm if this is a mistake in the book.
Thanks for your time, David Cawley _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
