Hi Francoise, So, how would the registrar know whether a GRUU is requested or not in the case described by Georg? Based on whether the gruu option-tag is present?
It would be good to clarify this in the outbound spec.

In GRUU only the instance-ID is needed to generate a GRUU. >For Outbound both, instance-ID and reg-ID are needed. > >My question now is, whether a GRUU will be generated when a REGISTER is received at the registrar, which indicates both reg-ID and instance-ID in the Contact >header. Reading outbound, it seems like instance-ID + reg-ID are *only* used for outbound purposes. > >Thanks a lot for your help. > >Best regards >Georg
