Yes, it makes sense. However I sitll think there would be some issues related to RTP timeout (the time the UAC waits until it decides there is no incoming audio). Such time would be at least a few seconds, enough fot the human who wouldn't hear ringing... -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
