      A user is complaining that after the broadcast module launches a call and the call is answered by the PBX , the call is never sent to the desired destination. It remains in silence for 30 seconds and then hangs.

      I searched through our Jira tickets and found this one: https://issues.freepbx.org/browse/FREEPBX-15897
      This Jira describes a similar behavior the customer is having.

      Si looking at the logs, the calls that are failing show the following:

      This call’s log is here:

      This is the original part of the dialplan in Asterisk set by the broadcast module: https://pastebin.freepbx.org/view/f1d2dd89

      In the mentioned Jira, Lorne suggests adding the following entry to the dialplan:

      exten => s,n,Playback(silence/50ms)

      This can be seen here: https://pastebin.freepbx.org/view/87ea337b#L9

      After reloading the dialplan, the call is answered successfully with two-way audio and it is transferred to the right destination:
