Hi,
For a basic call, when the UAS does not send a 200 within approx 4
seconds, the OpenSER has a timer fire and sends a 408 to the UAC and a
Cancel to the UAS. This only allows one ring on the terminating phone
before the call is dropped.. I'm attaching the log and Wireshark/snoop
capture file. I'll put the openser config file inline here. Please
advise:
