Last Call Review of draft-ietf-bliss-call-completion-18
review-ietf-bliss-call-completion-18-secdir-lc-atkins-2012-12-20-00

Hi,

I have reviewed this document as part of the security directorate's 
ongoing effort to review all IETF documents being processed by the 
IESG.  These comments were written primarily for the benefit of the 
security area directors.  Document editors and WG chairs should treat 
these comments just like any other last call comments.

   The call completion feature defined in this specification allows the
   caller of a failed call to be notified when the callee becomes
   available to receive a call.

The Security Considerations section mentions 'SPIT' but nowhere does
the document define the term.  What does it mean?

The SC section also mentions a "DoD" attack -- is the US Department of
Defence actually going to attack something?  Or does DoD mean
something else?  It's never defined.  Was this perhaps a typo of
"DoS", Denial of Service?  If so, I recommend you fix the typo but
also expand the acronym for those not necessarily familiar with the
term "DoS".
