I've updated an Internet-Draft giving condensed instructions for UA implementors on how to implement GRUU support. (This is updated for version -11 of the GRUU I-D, but it only discusses "public GRUUs", which is what we need for our environment.) In our product's environment (a "true SIP", proxy-based PBX), we've found that to do call control well, the UAs need to implement (public) GRUU. This I-D summarizes what UAs need to do
Guidelines for Implementing the GRUU Support in User Agents draft-worley-sip-gruu-implement-02 http://www.ietf.org/internet-drafts/draft-worley-sip-gruu-implement-02.txt Abstract Several applications of the Session Initiation Protocol (SIP) require a user agent (UA) to construct and distribute a URI which can be used by anyone on the Internet to route a request to that specific UA instance. A URI which routes to a specific UA instance is called a Globally Routable UA URI (GRUU). An Internet-Draft is progressing toward standardization that specifies procedures for proxies and UAs by which proxies can construct and delver GRUUs to UAs that request them. This document summarizes for UA implementors how to obtain "public" GRUUs and gives guidance on effectively using public GRUUs. Feel free to contact me with any comments.
