When I use the Transparent Server to register an IP extension, make or receive a call, the system will crash.
It always happens after "LinphoneCallStreamsRunning", in ms_filter_process().
2. call 219
After "219" accepts the call, the system will crash, the probability of occurrence is very high.
linphonec> call 219
2017-04-20 18:43:27:282 ortp-error-LinphoneCore has video disabled for both capture and display, but video policy is to start the call with video. This is a possible mis-use of the API. In this case, video is disabled in default LinphoneCallParams
linphonec> Remote ringing.
linphonec> Remote ringing...
