What makes you think that INFO goes end to end? An SBC can absorb it if it wants to. But this handling is not a bug, it's a feature. Since the SBC is call- stateful, it knows about the outgoing call, and thus can authoritatively say "Yes, this call was from Dan" without having to congest your low-rate end-link. -- dean _______________________________________________ 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
