I want to be able to allow a caller to dial a DDI system to verify identity etc (this is all done), I then want them to sit listening to music, until an event happens.
When this (external) event happens, I want to play a certain file to the caller, using playback (so that they have ff / rw etc), and when finished, go back to the music.
1) I thought of redirecting to an extension that played the file, and then jump back to the original Asterisk dialplan entry to start again. However, If I want to redirect, then this external event would need to know their channel.
2) I thought of a meetme / conference, but then they would not be able to control the playback of the file, right ?
Anyone got any other thoughts ?
