Francois, Thanks for your comments. Concerning your point about phone-context, I am not sure that this parameter is defined for a SIP URI (as opposed to a Tel URL). The only reference I can find in RFC3261 is an example at the end of 19.1.6. I agree that your proposed use of this parameter might be useful, but I am reluctant to propose anything without a clearer indication that this is indeed a standard part of the SIP URI. Any other opinions?

In any case, I've got a few comments: - I would like to see a mention of how to relate SIP URIs and tel URIs for QSIG phone numbers by putting an explicit reference to section 19.1.6 of RFC 3261. This could be somewhere in your draft, perhaps in section 11.2.2. - There doesn't seem to be much guidance in your draft of how to indicate QSIG type of number information using the phone-context. This is precisely the type of thing that the phone-context was created to do for "local" numbers (i.e., within a private domain). For example, a enterprise foo.com might decide to use the following mapping for NPI/TON to phone-context: NPI=Private ISO/IEC 11571, TON= phone-context= ----------------------------------------------------- level 2 regional number level2.foo.com level 1 regional number level1.foo.com local (level 0) number level0.foo.com PISN-specific number special.foo.com unknown number unknown.foo.com Of course, an enterprise could choose to use a phone-context of foo.com as the highest level of the phone number hierarchy, be it Level 2 or Level 1. Also, the host could be diffent that the domain in the phone-context: you could have foo.com in the phone-context and serviceprovider.net as the host domain. Also, this is just an example: the idea is that the enterprise would assign diffent phone contextes to different QSIG types of number. This would yield SIP URIs like sip:53756;phone-context=level0.foo.com@foo.com;user=phone sip:265-3756;phone-context=level1.foo.com@foo.com;user=phone sip:6-911;phone-context=secial.foo.com@foo.com;user=phone This is probably something that should also go in section 11.2.2. All this is very much in line with draft-antti-rfc2806bis-08. > -----Original Message----- > From: Elwell, John [ mailto:john.elwell@siemens.com <mailto:john.elwell@siemens.com> ] > Sent: Thursday, May 29, 2003 07:38 > To: 'sipping@ietf.org' > Subject: RE: [Sipping] I-D > ACTION:draft-elwell-sipping-identity-interworki ng-00.txt > > > This document has been produced in ECMA, and comments of the > SIP community are invited prior to finalisation of the ECMA > publication during the coming weeks. > > john.elwell@siemens.com > > > > -----Original Message----- > > From: Internet-Drafts@ietf.org [ mailto:Internet-Drafts@ietf.org <mailto:Internet-Drafts@ietf.org> ] > > Sent: 29 May 2003 12:20 > > Cc: sipping@ietf.org > > Subject: [Sipping] I-D > > ACTION:draft-elwell-sipping-identity-interworking-00.txt > > > > > > A New Internet-Draft is available from the on-line > > Internet-Drafts directories. > > > > > > Title : User identification in a SIP/QSIG environment > > Author(s) : J.
