No, what is happening there is that you are fetching a (empty) value
from the non-existent variable ROOM and substituting it into the command.
The same with PIN. So the command that is actually being invoked is:

MeetMe(,rsxA,)

You seem to be expecting Meetme to populate those variables, but in fact
it doesn't even know you had them in your dialplan statement.

If you want MeetMe to populate a variable with the chosen room, you will
need to modify the source to do so. Alternatively, you can put in some
dialplan logic to ask the user for the room number before calling MeetMe,
and putting the chosen number in ROOM using Read() or similar. Then if
your caller has chosen room 1234 for example, the call to MeetMe would
be like this:

MeetMe(1234,rsxA,)

and MeetMe would then go straight to that room without asking.

The channel does still exist, but in the hung up state. The channel structure
and variables don't disappear until the 'h' extension is finished.

Hope this helps
