All,
If a UAC performs multiple outbound registrations (reg-id=1 & reg-id=2)
and uses GRUU, the outbound examples show it uses different Call-IDs.
Does that mean that the second registration invalidates the temporary
GRUU returned in the first 200 OK?
Based on the GRUU spec, it would. I believe that the UA has to use the
same Call-ID for both reg-id.
In other words: should the temporary GRUU returned for the first Contact
be the same, or different?
Well, it should be different no matter what. The registrar is supposed
to generate a new temporary GRUU on every register.
Should outbound recommend to use the same Call-ID for multiple
registrations? (and different from-tags)?
Yes.
