[Asterisk-Users] MeetMe conference

[JKNUTSEN at UP.COM]

I am attempting to add a bit more functionality to the MeetMe conferences
hosted on my Asterisk PBX.  I have found where I can add options as a user
enters the conference such as |p, which allows them to exit the conference
when they dial a "#", or |m, which allows them to enter the conference
where they can monitor only (their audio is muted).  The problem that I am
having is that once a user enters the conference under the option monitor
only, they are unable to leave the conference via the "#", even when option
"p" is included.  Does the monitor only option cause Asterisk to stop
receiving all audio from that channel, or is there something that should
still be able to detect the DTMF?

Also, I would like to set some sort of variable for when a user enters the
"#" key and leaves a conference that would store the confnum that they were
in.  This way they could enter "#" followed by some digit, a 5 for example,
that would bring them right back into the same conference, but this time
they are monitor only.  I think it would look something like this in
extensions.conf

exten => 4000,1,MeetMe,|pqs

exten => 5,1,MeetMe,confnum|mpqs
exten => 6,1,MeetMe,confnum|pqs

With this set up, a caller could enter #5 in a call to mute themselves, and
#6 to unmute themselves.

I think I have found in app_meetme.c where I could set this variable, but
what other file(s) would I need to touch to make this happen?

Thanks in advance,
