Missing UI notification when calling with ZRTP to a client that doesn't support it
Hello!
If we set the media encryption ZRTP and we make it mandatory and then we call someone who doesn't support it like thetestcall@sip.linphone.org the call is established but there's no sound.
I believe this behaviour is correct but it should be improved: 1- Since there's no point in having a call without sound (my opinion), the call shouldn't be established, and the initiator should be informed that it was not possible to use encription, to disable it and start a new call.
2- if having a call with no sound is required, the user should be asked prior the call establishment how he wants to proceed. If he wants to terminate, or to continue to establish the call even without sound. In the last case there should be a warning in the screen informing that there's no sound because there's no zrtp
