Exec playback app on an active call

First of all, sorry for my english, is not my mother language. i am new in this scene.

I would like to know if it is possible to use playback application on an active call ,

i use AMI to originate a call, first call SIP/9999999@out-trunk , then bridge with exten=1004,contex=internal-trunk,prior=1.

in this active call i can exec playback app ??

thx 4 all

Playback app runs on a channel. Bridge and the implied bridges in Dial and Queue, run on channels. You cannot run more than one application at a time on a channel.

You would need to run Playback on a local channel, and either connect in using the chanspy mechanism to the other channels, or redirect the two originals and the local channel into a conference bridge.
