Call Processing Language : A Language for User Control of Internet Telephony Services
RFC 3880, “Call Processing Language : A Language for User Control of Internet Telephony Services”, is a Proposed Standard document published in November 2004 by J. Lennox, X. Wu, H. Schulzrinne. The canonical text is published by the RFC Editor.
Abstract
This document defines the Call Processing Language (CPL), a language to describe and control Internet telephony services. It is designed to be implementable on either network servers or user agents. It is meant to be simple, extensible, easily edited by graphical clients, and independent of operating system or signalling protocol. It is suitable for running on a server where users may not be allowed to execute arbitrary programs, as it has no variables, loops, or ability to run external programs. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
