At the time I wrote the message you responded to, I had forgotten that for the registrar to construct a GRUU, the phone must provide an instance ID (although the phone does not need to support GRUU per se). So I omitted the unknown-param element. But as you point out, if pub-gruu is present, then unknown-param/+sip.instance will be present. > > The recipient of this document can access this UA via > > "sip:[EMAIL PROTECTED];gr=hha9s8d-999a", or > > "sip:[EMAIL PROTECTED]:my.path.com", or > > "sip:[EMAIL PROTECTED]", depending on which components of reginfo it > > understands.

The usual terminology is that "sip:[EMAIL PROTECTED];gr=hha9s8d-999a" is the GRUU (since a GRUU is always a URI). "hha9s8d-999a" would be called "the gr parameter value". In principle, the registrar (or whatever) is allowed to construct GRUUs pretty much however it wants, with the single restriction that the "gr" URI parameter must be present (with or without a value). The "gr" parameter is what marks the URI as a GRUU. But in our case, its presence as the content of the pub-gruu element also ensures that it is a GRUU.
