I am new to asterisk. I have connected PSTN landline to asterisk via Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface (elastix UI detected as Wildcard TDM400P REV I Board 5) card. Problem is when call is disconnected from landline, ivr is still playing. asterisk is not detecting the call disconnection. I have set the busypattern=400/750,0/750 from the World Tone Database. but still no luck. surprisingly only one time asterisk detected the call disconnection and prints log to console as -User disconnected
-Hanging up dhadi.
i have noticed that the call connection has some noise and audio is not loud and clear. is that problem with board or landline connection or with wrong configuration. Please help me to fix Call Disconnection Detection problem.
