[HELP] MeetMe: Need to play audio file to all users

I have looked all over the Internet for a solution like this but I have found nothing substancial to help solve this problem.

I would like to play an audio file to all members of a MeetMe conference, like a notification. Does anyone have any idea about how to do this? I was thinking that it would be nice if i could just open a new channel, redirect that channel to the conference room, play the file, leave the conference room, and hangup the channel. Maybe my logic is way off so I am open to all suggestions.

Thanks!!!

I was able to come up with a solution that works adequately.

This solution uses local channels, which I didn’t even know existed until 15 minutes ago.

Basically, you create a context and extension that will be used to playback the file you want everyone to hear. Then using the Asterisk Manager you originate a call from that context using a local channel like this:
local/extension@context.

Thats it!
