Re: [Linphone-developers] Linphone for Windows Phone Crash - System.Exce

I assume the crash is caused by some message received from the server after success registration. Could some invalid message from Asterix server (maybe in HTTP header params) cause this crash? Are there any invalid chars that are not accepted?

Any advice is welcome. 

Thank you,

This means there has been a crash in the background process. Could you try again setting the debug mode to Native for the project. You should get a more useful backtrace then.

I get the git source code for Windows Phone (linphone-wp). I pass all steps from readme file and successfully compiled the project. I'm using Visual Studio 2013. I deploy the application. I can access any screen, but after I enter valid connection data for a real SIP account and after success register with a SIP account I receive this error and application crash:

I tried on emulators and also on real device (Lumia 640 XL WP8.1 Update 2) and I get the same error.

The log on the phone does not contain any error message.

If I enter, let say wrong password, a "bad credentials" message is received. The crash happen only after success registration on SIP server.

Please help me to fix this issue. Any advice is welcome.
