I have a cisco as5400 as voip gateway, when call coming in from PSTN T1, the gateway send invite to our sip server, the sip server send back 100 trying, but didn't send back 180 trying within about 10 seconds, the cisco send cancel to sip server to end the call, how can i change the cisco configuration to let wait cisco wait longer for the 180 ring back?
