Would this work?

Hack up meetme to add an option to time out after x seconds, set 
MEETME_STATUS to "TIMEOUT" and return to the dialplan. You can follow the 
"w" option to figure out how to pass the seconds. Then in meetme's main 
loop (in conf_run()), just check for when its time to leave.

Use dial()'s G option to put both the caller (with the timeout) and the 
callee into a meetme.

When the caller times out, the callee will hear the music on hold ("please 
wait until the other party returns").

The caller can top up and then return to the meetme. You can accumulate 
the time the caller is in the meetme.

What happens if the caller can't top up and hangs up. Who pays for the 
callee leg? Would you need a second timer to abort the callee?

Thanks in advance,
