I have Telephony setup based in Saudi Arabia,Qassim, 1 VG-4331 with FXO card and two analog lines, CUCM-12, CUC-12.
Everything is working fine, except two issues
If i call from outside after greetings is played, if i disconnect the call with out any input, FXO hangs.
while if i transfer call to operator or extension, call is established and when far user disconnects the call , FXO shows still busy and on ip phone call is still active and if i end the call on ip phone fxo port is released.
Outgoing Call - call get disconnects after 1min automatically.
Below is my router config
