Hi,
In 3GPP, it is true that the UE inserts the service URN into the
Request-URI.
But, in the current specification the E-CSCF converts the URN into a
routable PSAP address, i.e. the mechanism in the loose-route draft is
not used.
Why was this done? Do you expect that the call uses a different
emergency call marking technique went it enters the PSAP operator network?
Do you expect that the call is directly sent from the E-CSCF to the PSAP
and that there are no other hops in between?
Regards,
Christer

Hi Dean,
in ECRIT we assumed that the Request URI contains the service
URN. We put that stuff into the Phone BCP document (which
unfortunately still contains an error I just noticed).
That's what we told the 3GPP in the past as well. Hence, they
wrote it in their specs. See TS 24.229, Section 5.1.6.8.3, bullet (1).
Within the ECRIT group we weren't aware that this issue has
not been decided and hence we are a bit concerned about the
recent change given that other SDOs followed our suggestion already.
Do you have an idea what we should do now?
Ciao

Dear SIP WG members,
during the ECRIT meeting we learned that the SIP working group
"rejected" the concept described in
draft-rosenberg-sip-ua-loose-route-01.txt.
Could someone please give us more information about this
decision as
it impacts the work we do in ECRIT?
I wouldn't say that UA Loose Route was "rejected" so much
as "does not
yet have consensus".
This is in part influenced by "WG doesn't seem to have a compelling
reason to make such a significant change."
Perhaps ECRIT has a compelling reason?
