Summary:
This draft is basically ready for publication, but has nits that should be fixed before publication.

Comments:
This is a well-written document about using SIP through a NAT, including handling information that needs to flow inbound through a NAT towards a User Agent and keep-alive techniques for connections that may pass through a NAT.

The only nits worth mentioning are a couple of RFC reference issues found by idnits 2.11.11:

  ** Obsolete normative reference: RFC 3489 (Obsoleted by RFC 5389)

  -- Obsolete informational reference (is this intentional?): RFC 4346
     (Obsoleted by RFC 5246)
