Summary: This draft is almost ready for publication as a Proposed
Standard, but has some minor issues that need to be fixed as identified
in my last call review dated 2013/04/16. One of the issues I raised was
clarified as common practice in the RAI wgs and I have removed it from
the list. The authors had agreed to fix the following issues but I have
not seen an updated draft yet.


* Section 4.1

There is no error handling specified. i.e. What happens if the server
does not send a 101 reply with sip in the Sec-WebSocket-Protocol header?

* Section 5.2.2

RFC4168 does not update transport-param. Is this a copy and paste error?

* Section 5.2.4

Maybe it is just me, but the way I read it, this section leaves the
client without any mandatory to implement transport protocol for SIP
since it relaxes the need to implement UDP and TCP, as well as allowing
the implementation of the websocket transport using a MAY.
