Btw, I'm not sure 27 DESTINATION_OUT_OF_ORDER is the best cause in this case. Two other options I see suitable are 102 RECOVERY_ON_TIMER_EXPIRE and 604 MEDIA_TIMEOUT. Does anyone know is there an official mapping between Q.850 codes and various GSM cause codes?
Another useful change here would be to propagate information about which timer expired. That would help to gather information about issues with the network.
