[Asterisk-Users] Sip channel remains active indefinitely

[Sharon]

Hello,

In our company we are using Asterisk-cvs-Head with realtime. I am not
able to figure out a issue wherein the sip channel stays active
indefinitely.This happens when a call is in progress and the person
who called doesn't hangup normally but in between the conversation his
ATA gets unregistered or becomes unresponsive.The channel stays active
indefinitely and is seen as a active channel in sip show channels.
Doing a soft hangup on that channel I am able to kill it but looking
for a better solution to avoid this from happening.

Any suggestions would be appreciated.
Thanks,
AG
