More than that, they have no capacity to use any AGI script at all. If they
try to, they get no audio.

I have no experience of actually trying to use AGI, but Zap channels can
use an AGI script.

It certainly looks from the app_meetme.c code that each Zap channel runs its
own copy of the AGI script.

Looks like it.

Note that using an AGI script loses other built-in functionality too, like
mute/unmute, kick, and MOH while there is only one user.

I can't see a reason why Zap and SIP channels couldn't use different
extensions to get to the same MeetMe room with different flags and (for the
Zap channels) different AGI scripts .

I'd be interested to hear how you get on!
