There's an issue with SDP/media stream with iOS SDK.

Here's the SDP which sends the OpenWebRTCWebView on iOS simulator:

Here's the SDP from same web app working correctly on the same machine with Chrome browser:

The webrtc handling in web app is done by newest version of sip.js library.

Hi @urbaniak could you share some more info on what does not work? All I see above is two similar SDPs.
