hi i have a call file as below. it sends the call to context
exten => 21,1,Answer()
exten => 21,n,Wait(5)
exten => 21,n,Playback(custom/basalam)
exten => 21,n,AGI(khareji.php)
when call file is running the playback executes before the pair answer the call. i used wait application to postpone the playback app. what should i do to play the sound after answering the person.
thanks in advance
