Folks, I've just submitted an update to the GRUU specification. Until it appears in the archives, you can find it at: http://www.jdrosen.net/papers/draft-ietf-sip-gruu-01.txt The differences are: * removed requirement that the gruu be constructed in such a way that the contact and/or AOR can be determined from it * indicate that a gruu can be obtained by the register mechanisms in the specification, but that other mechanisms are also possible * The gruu is now associated with the instance ID of the UA. The instance ID is defined as a callee capability parameter. The specification now includes a UML diagram showing the relationships between GRUU, AOR, Contact URI and instance ID. * Added registration of the sip.instance media feature tag The biggest change is the third. Indeed, it seems like we have three drafts this round that discuss instance identifiers in SIP: http://www.jdrosen.net/papers/draft-ietf-sip-gruu-01.txt http://www.ietf.org/internet-drafts/draft-jennings-sipping-instance-id-00.txt http://www.ietf.org/internet-drafts/draft-stucker-sip-guid-00.txt all three are similar. Mine uses a contact header field parameter, and uses the callee capabilities framework to enable caller preferences routing based on instance iDs. Cullen also uses a contact parameter, but not within the callee caps framework. Brian defines a header field. I'll post a separate not starting a thread on the pros and cons of the various approaches. Thanks, Jonathan R. -- Jonathan D.
