No, that's not at all the main reason. RFC4474 is already not end-to-end. It's signed by a middlebox in the originating domain, and verified by a middlebox in the terminating domain. There is ample opportunity to change the SDP at either of those domains to perform lawful intercept. The main reason to change SDP is to steer the media, for numerous reasons. -hadriel _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [email protected] for questions on current sip Use [email protected] for new developments on the application of sip
