If you look at the following page:
http://www.voip-info.org/wiki/index.php?page=Asterisk+cmd+Congestion
You can see there the following:
"Sends a signal to inform the channel of congestion. This command waits
for the user to hang up; it does not continue execution of further
commands."
"new in asterisk 1.2: Now this app supports an optional 'timeout'
argument. If the optional timeout is specified, the calling channel
will be hung up after the specified number of seconds. Otherwise, this
application will wait until the calling channel hangs up."
A little google or a search on the above site will answer most of your
questions.
