asterisk users - Nov 2006 - MeetMe, background agi and playing sounds

Hello everyone!

I have created an background agi which responds to dtmf 0-9, each key
should playback a sound, and it does, but here is the problem.

The sound which is played is just played to the person who touches the
key, not to everyone else in the conference, does anyone know how i
can do so the sound is heard by everyone?

One more thing, is there a way to mute/unmute a channel within the AGI?

Thank you!
