Several newly developed languages and interfaces, such as the CPL and SIP CGI, allow users or administrators to specify how Internet telephony servers should process calls. There needs to be a method of transporting scripts for such languages between a client and a server. This document proposes using the payload of SIP REGISTER messages, and their responses, as one method to transport them.
