Hello.
I am trying to make a call with Zoiper between my android phone and desktop, but when I call from the android app to the desktop it rings for a moment and then ends the call and says "Unparsable SDP (code: 28)".
Then if I try calling from the desktop to the android app it appears to ring on the desktop, but the phone doesn't get the call.
All audio codecs are enabled. Any suggestions?
