This feature provides support for Globally Routable User Agent (UA) URI (GRUU), according to RFC 5627. This is used for obtaining a GRUU from a registrar and for communicating a GRUU to a peer within a dialog. This support is provided by the existing parameter EnableGRUU.

A GRUU is a SIP URI that routes to an instance-specific UA and can be reachable from anywhere. There are a number of contexts in which it is desirable to have an identifier that addresses a single UA (using GRUU) rather than the group of UA’s indicated by an Address of Record (AOR). For example, in call transfer where user A is talking to user B, and user A wants to transfer the call to user C. User A sends a REFER to user C:

REFER sip:C@domain.com SIP/2.0

From: sip:A@domain.com;tag=99asd

To: sip:C@domain.com

Refer-To: (URI that identifies B's UA)

The Refer-To header needs to contain a URI that user C can use to place a call to user B. This call needs to route to the specific UA instance that user B is using to talk to user A. User B should provide user A with a URI that has to be usable by anyone. It needs to be a GRUU.
