Here is the log. Pushed the button on 12:48, and picked up with softphone couple of seconds later. In the softphone I looked like it connected, but no sound or video. The doorbell on the other hand keeps ringing. Doorbell timed out one minute later.

Hello
I bought the DS-KD8003-IME door bell.
I was able to get it up and running (and updated) and changed the netword protocol to SIP because I don't want to have a hikvision indoor station with its limited functionality.
I then made a SIP server with FreePBX, witch only the ulaw and x264...
