Summary:                    Avoiding deadlock for channel problem
Description: 
Hello, 

I have HP Proliant server with 1 E1 and 8 BRI Sangoma cards installed. I
have noticed that in period of one day I have and error, when user calls,
hears 'ringing' alert, agent answers, but user still hears 'ringing' tone.

I set debug mode in logger.conf and I noticed that when calls enters the
queue, and starts ringing 'Avoinding deadlock for channel' errors appears
and repeats many times.

All debug information is attached.
