[asterisk-users] Hung channel problem with 1.4.26.2

Hi,
I have a case where SIP channels will not be destroyed, resulting in
further calls to ChanIsAvail() to fail.
The process (I believe) to replicate this is the following:

- Make a call to another SIP phone that is an "intercom" call (Auto-Answer)
- For whatever reason, the phone happens to go UNREACHABLE during this call
- Phone comes back REACHABLE, but channel still exists in "core show channels"

As an example, here's 3 stuck calls from today:

root at hades:~# asterisk -rx "core show channels"
Channel              Location             State   Application(Data)
SIP/6296-a2298 (None)               Up      AppDial((Outgoing Line))
SIP/6315-a0906 *806296 at ext-in Up Dial(SIP/6296|5|A(beep))
SIP/6333-a131e (None)               Up      AppDial((Outgoing Line))
SIP/6294-a24fc *806333 at ext-in Up Dial(SIP/6333|5|A(beep))
SIP/6297-a1cb7 (None)               Up      AppDial((Outgoing Line))
SIP/6315-adc5d *806297 at ext-in Up Dial(SIP/6297|5|A(beep))
....

I don't know if this has been fixed in a later 1.4.x version, though
after reading some of the
DTMF relaying problems with 1.4.27 and beyond, I don't think I would
want to upgrade...

Thanks.
