There is no limits. Usually PSTN providers terminates the call after 60-120 seconds ringing. A proxy can also terminate the INVITE transaction by sending a CANCEL to the ringing branches and a 408 to the UAC. Also, most of the UA's can be configured to cancel a call after N seconds ringing. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
