GRUU (Globally Routable User Agent URI) support
The VCS has implemented the Public GRUU element of RFC 5627: Obtaining and Using Globally Routable
User Agent URIs (GRUUs) in the Session Initiation Protocol (SIP).
A GRUU is a SIP URI that can be used anywhere on the internet to route a request to a specific AOR
instance. Note that the registering domain must be globally routable in order for the VCS to support GRUU.
