Introduction This document analyse those kind of services which allow user to allocate its extention address which can be used as indications to route to its currently associated UA. Different from GRUU, this requirment is in service level and is controlled by the user himself Xu Expires August 31, 2006 [Page 3] Internet-Draft The User-registered Routable UA URL February 2006 2. Terminology In this document, the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in RFC 2119 [1] and indicate requirement levels for compliant implementations. Xu Expires August 31, 2006 [Page 4] Internet-Draft The User-registered Routable UA URL February 2006 3. Analyse This is the typical user experience requirements for these kind of servicec: Req 1: One user have multiple SIP UAs which share the same AOR. Req 2: The user can dynamically allocate its prefered extention id for each UA which are all associated with the same AOR. Req 3: The other caller can make use fo the AOR and extention id to route to the associated UA. Req 4: The extention id is allocated by User itself, not controled by the network.
