Call disconnecting in exactly 60 minutes. Getting an announcement “you have only 10 seconds remaining” @59 minutes and 50 seconds.
Asterisk doesn’t do this by default, although it can be configured to do so. An upstream carrier could also do such a thing. You’ll need to provide further information such as configuration and console output.
Thanks for the suggestion. I shall once look into the termination as well.
You should also check your call logs and see if there is anything in your dialplan playing this announcement and disconnecting the call.
