Hi everybody. I have installed an UC 320 to a client. There is a small issue with the disconnect tone. We have 3 FXO lines connected with 2 different telco. FXO2 and 3 correctly detect the disconnect tone from one telco, but the FXO1 that is connected to another telco does not recognize the disconnect tone and the VM records 10 mins of tones...
The tone after disconnection on FXO1 is similar to the busy tone, so I would like it to disconnect after some 6/7 seconds (this in order the line to not be immediately disconnected also when somebody calls a busy number). I also recorded a bit of the tone in case needed. Is it possible to regulate the disconnect tone detection just for FXO1?
