The phones in question are configured with one line that will
except only one call. The device itself does not think it is in-
use because it will accept another call. Something in the SIP
channel driver is not clearing the state when a call is completed.
There is definitely no correlation between this and Asterisk
restarting. In fact, if a device is 'stuck' on in-use,
restarting Asterisk will clear the state.
I've been working on this for a week now. It only started for
us because I just implemented the call-limit option in the
sip.conf in Asterisk for the devices. See my posts with subject
'Queue and Interface time out'.
I believe there is/was a bug relating to call-limit. Buddy Watch
doesn't work if you use call-limit and if a call from a queue is
transfered, the call-limit is not released until the original
call is terminated. I do not know if these issues have been
fixed or not.
Again, a relation to call transfer. I think the bug is that we
don't handle call-limits properly during a call transfer. That needs
to be verified and fixed.
There may be, but transfers are not the cause of the issue I
describe. SIP interfaces that are members of a Queue, will
erratically not be released from 'in-use' when a call is
completed. I have tested with both caller terminated and agent
terminated calls and both will cause this behavior. It happens on
approximately 20% of all calls the queue members receive. Dialing
the SIP device with another device will immediately free the status.
I wonder if this only happens on calls sent to the SIP device by
the Queue application. I will test that today.
If you are using chan_agent as a proxy channel, check if that changes
things.
