1 Introduction


The Session Initiation Protocol (SIP) Registration Extensions protocol specifies proprietary extensions to Session Initiation Protocol (SIP) registration procedures. It also defines a provisioning protocol to enable SIP clients to obtain server provisioning data from SIP servers compliant to this specification. It is expected that the provisioning protocol sequence is performed during the client bootstrap process and that the data obtained is used for subsequent protocol operations attempted on the network.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
