The GRUU SIP extension  has been recently added to OpenSIPS trunk and
it will be present in the 1.8 release.
A GRUU ( Globally Routable User Agent URI ) is specifically designed to
implement reliable routing to a specific device for an end user. While a
plain SIP URI, such as username at opensips.org, is a URI that refers to a
user, a GRUU is a URI that refers to a specific device.
Certain SIP scenarios ( REFER for example ) rely on the fact that a
given URI will route to the specific device, but prior to the GRUU
extension there was no mechanism to reliably do this.
The Registrar and Usrloc modules have been enhanced to support GRUU at
the server side, so OpenSIPS will be able to generate public and
temporary GRUUs to phones that support the GRUU extension, and it will
also be able to properly route requests that target a GRUU.
