Scheduled broadcast dialplan application​

<action application="sched_broadcast" data="+10 playback::/tmp/foo.wav"/> 
<action application="sched_broadcast" data="+10 playback::/tmp/foo.wav bleg"/> 
<action application="sched_broadcast" data="+10 playback::/tmp/foo.wav both"/> 
<action application="sched_broadcast" data="+10 playback!normal_clearing::/tmp/foo.wav"/>
<action application="sched_broadcast" data="+10 phrase::warning"/> 
<action application="sched_broadcast" data="+10 phrase!normal_clearing::goodbye"/>
  • The optional !<cause_code> can be added to make the channel hangup after broadcasting the file.
  • The optional bleg/both parameter specifies which leg of the call to broadcast the file on. If not specified, the broadcast only occurs on the a-leg.

sched_broadcast +10 <uuid_str> playback!normal_clearing::/tmp/foo.wav
  • The optional !<cause_code> can be added to make the channel hangup after broadcasting the file.
