[Asterisk-Dev] clearing 'stuck' channels

[Jared Mauch]

	I'm seeing a case where I get a large number of 'stuck'
channels as it relates to users that sit behind poorly behaving
nat devices.

	these calls tend to be initiated and have unidirectional
voice (eg: we can hear the user behind the nat, but not the
other way around ..)

	this means that messages can't be sent to them (and get ACK)
saying that they will terminate the call, etc..

	is there a way that i'm unaware of to time these out, or
is this what I think it is which is a bug where the call/channel gets
stuck until such time as it can be terminated?
