No. It allows the uas to provide the offer. This can be an offer to keep the call on hold, or an offer to take the call off hold, or an offer to add more media, etcetera. > Is this behavior mentioned somewhere in RFC. RFC 3261 section 14.1: "Of course, a UAC MAY send a re-INVITE with no session description, in which case the first reliable non-failure response to the re-INVITE will contain the offer (in this specification, that is a 2xx response)." _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
