How exactly do the two parties to a SIP phone call negotiate the media format? I see that the INVITE message contains a list of the inviter's supported formats, and the Status: 200 message contains a list of the responder's supported formats but RFC 3261 doesn't explain how this results in a negotiated protocol.
Many thanks. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
