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.
