Indeed, and that's what we're using. We find this to give better 
performance than the manager interface.

To get back to the original question, we need to tell the current caller 
(the one this AGI is connected to) whether another caller is still 
connected. The AGI has an array of other uniqueids it pulls from a 
database, but it needs to verify these with Asterisk as the database can 
be out of date.

 From what I'm hearing so far, it sounds like we're going to have to use 
the managaer interface.
