I'm having a lot of fun with the Asterisk Manager Interface (AMI). Where I previously relied on .call scripts to start stream the conversation in the conference room, I now have a button on the conf. mgr. interface (pic below).
The Kick and Mute/Unmute buttons are kinda obvious. The "Muzak" button starts playing music into the conference room. The stream button starts streaming the conference room to a local Icecast server. The "trick" behind these last two buttons is the "Originate" function call in the AMI.
Next up: being able to edit the caller's name and their topic (can you guess where I'm going with this?) and being able to push callers back and forth between queues and conference rooms. Maybe a bridge between conference rooms?
