[asterisk-users] Newbie MeetMe: How to control max users in conference?

Thanks Tony for your advice.
Below is a working version of a Meetme extension which a) check the
conference room number and b) restrict the max size of the attendees of
each conference room.
The good thing is that we only need to program one extension for all
conference room instead of one for each.
The down side is that I have to hard code the conference room numbers
and the max size (which is not good from a good programmer's point of
view).
