Greetings,

I am trying to get a call working with webrtc, but getting below error upon answer.

Failed to set remote answer sdp: The order of m-lines in answer doesn't match order in offer. Rejecting answer.

I have examined the both invite and 200 ok sdp, and i don't see the m= line order being changed between them.

So seeking expert help on this one.

Pasting whole console logging below.
