I use c3845 as SBC. During peak hours when it is serving about 600 concurrent calls often following error occurs:
Dec 2 20:08:03: %CALL_CONTROL-6-CALL_LOOP: The incoming call has a global identfier already present in the list of currently handled calls. It is being refused.
After it appear many calls are dropped.
I know that call identifier number is limited, but limit is 65535 so I do not think we reach it. I can not find any solution for this error. Did you ever meat such problem? What is your solution?
