I have a running asterisk now server for a long time without any issue. My server record the call and it play a “beep” tone every 30 second time interval. The feature is enabled on sip general setting globally. Now I need is I want to disable that “beep” tone for specific trunk. I saw with macro-dialout-trunk-pre-hook i can do this job. But couldnt find a good source, how i can do it.
Any one have a clue.
