Why two UA instance? What is the use case? If UA want's to register with 2 flow say 2 proxies we can have same Instance-id and vary the reg-id value. Regards, Karthikeyan.G -----Original Message----- From: sip-bounces@ietf.org [mailto:sip-bounces@ietf.org] On Behalf Of Bob Penfield Sent: Tuesday, October 14, 2008 11:08 PM To: Elwell, John; Christer Holmberg; Juha Heinanen; sip@ietf.org; Paul Kyzivat; Dean Willis Subject: Re: [Sip] Dual registration without Outbound I guess the problem arises when you want to do a single REGISTER request for both instances. If I the use case correctly, the UA would send two REGISTER requests (one on each interface) and both REGISTERs would have the two Contacts (one for each instance-id). Something like this: First REGISTER to Outbound-proxy #1 REGISTER sip:example.com SIP/2.0 Via: SIP/2.0/TCP 1.1.1.1;branch=z9hG4bKnashds7-1 From: Bob <sip:bob@example.com>;tag=7F94778B653B-1 To: Bob <sip:bob@example.com> Call-ID: 16CB75F21C70-1 CSeq: 1 REGISTER Supported: path, outbound Route: <sip:ep1.example.com;lr> Contact: <sip:bob@1.1.1.1;transport=tcp>;reg-id=1 ;+sip.instance="<urn:uuid:00000000-0000-1000-8000-AABBCCDDEEFF>" Contact: <sip:bob@2.2.2.2;transport=tcp>;reg-id=2 ;+sip.instance="<urn:uuid:00000000-0000-1000-8000-BBCCDDEEFF00>" Second REGISTER to Outbound-proxy #2 REGISTER sip:example.com SIP/2.0 Via: SIP/2.0/TCP 2.2.2.2;branch=z9hG4bKnashds7-2 From: Bob <sip:bob@example.com>;tag=7F94778B653B-2 To: Bob <sip:bob@example.com> Call-ID: 16CB75F21C70-2 CSeq: 1 REGISTER Supported: path, outbound Route: <sip:ep2.example.com;lr> Contact: <sip:bob@2.2.2.2;transport=tcp>;reg-id=1 ;+sip.instance="<urn:uuid:00000000-0000-1000-8000-BBCCDDEEFF00>" Contact: <sip:bob@1.1.1.1;transport=tcp>;reg-id=2 ;+sip.instance="<urn:uuid:00000000-0000-1000-8000-AABBCCDDEEFF>" Thus the UA could receive requests for either Contact on either of the two outbound flows. Is having two UA instances in the same request legal with the current text? cheers, (-:bob -----Original Message----- From: Elwell, John [mailto:john.elwell@siemens.com] Sent: Tuesday, October 14, 2008 11:02 AM To: Bob Penfield; Christer Holmberg; Juha Heinanen; sip@ietf.org; Paul Kyzivat; Dean Willis Subject: RE: [Sip] Dual registration without Outbound > -----Original Message----- > From: sip-bounces@ietf.org [mailto:sip-bounces@ietf.org] On > Behalf Of Bob Penfield > Sent: 14 October 2008 15:41 > To: Christer Holmberg; Juha Heinanen; sip@ietf.org; Paul > Kyzivat; Dean Willis > Subject: Re: [Sip] Dual registration without Outbound > > For both GRUU and Outbound a given instance-id > (+sip-instance) actually represents a single UA contact > instance rather than just a single User Agent.

[JRE] In an earlier email I was trying to say roughly the same thing, except the way I looked at it was that a device with multiple interfaces would logically contain a UA for each interface, and each UA would than have a single instance ID. In that case the text in section 4.1 still works.
