[Linphone-developers] When use the Transparent Server to register an IP extension, make or receive a call, the system will crash

[cloud]

Hi All,

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().

steps: 1. register an IP extension through transparent server, e.g. address@hidden:5090

           2. call 219

After "219" accepts the call, the system will crash, the probability of occurrence is very high.

           

 

Here are some logs and information:

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
