Summary: This document is ready for publication as a Proposed Standard RFC.  I have a few minor comments that should be considered s they may improve future understanding of the document.

Major issues: None

Minor issues:
    In reading section 4.2 and 4.3, I believe I can guess at certain intended behaviors, but it is not as clearly stated as I think is desirable.  There is also one odd statement in section 4.3

    Taking the odd statement first, the text in section 4.3 refers the active answerer "towards
   the IP address and port of the offerer".  But when WebSockets is used, one does not connect to the IP address and port, but to the URI specified.

    I believe that the intent in 4.2 and 4.3 is that whichever side will be "passive" is required to provide an a=ws-uri or a=wss-uri so that the other side can establish the connection to the URI.  But section 4.2 does not say that.  And the text in section4.3 that talks about providing the URI in the a= does not qualify whether it is required with active, passive, or both.  

Nits/editorial comments:  N/A
