Dear Sir,
I did 2 calls from the same endpoint to the same number and get 2 different
IDs but still forwarding the calls to X.X.X.X as follow:
Call1:
call-id for this call 56549e09d94c1430Jul 30 17:00:32 [10607]
DBG:carrierroute:get_route_tree_by_id: searching in carrier default, id 5

Any suggestions?
