asterisk users - Feb 2007 - Rules about congestion

On my wild learning curve, I encountered numerous occasions when a channel 
remained in "Congestion" state after a Congestion() step without going
to
the next step, which is Hangup().  I couldn't find a definite pattern but it
seems to happen when a channel is hung up by the other party or by some 
other action.  Any recommendation about preventing such?

	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.
