[Ieprep] Diffserv Code Point for Emergency calls

Hello,

I understand this might have already been discussed (a lot) on the list
but I would like to voice my feedback.

I read
http://www.ietf.org/internet-drafts/draft-ietf-ieprep-framework-10.txt
and was somewhat puzzled at section 4.1.2. I understand that the IETF
wants to be conservative in standardizing new DSCP, but it seems to an
emergency call DSCP would be accepted by the community (am I wrong?).

I am talking to customers and facing an implementation dilemma on "how
to convey better than EF treatment in a standardized manner since normal
voice calls already use EF?" Should normal voice calls be demoted to use
AFXY DSCP?

Yes, I know, customers can define their own DSCP, map to a specific
queue in their routers, etc, etc. All this is good. However, the
feedback I am getting is that they would like a standardized DSCP for
emergency. The recent tragedies accentuated the need for such
standardization.

I understand there are several levels of emergency calls, etc but maybe
we could start conservative and define _one_ DSCP for emergency calls?

Thanks,

Reinaldo
