Technical Summary The Call Processing Language (CPL) is a language that can be used to describ and control Internet telephony services. It is designed to be implementable on either network servers or user agent servers. 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. Working Group Summary The IPTEL WG supported the advancement of this document. Protocol Quality This document was reviewed for the IESG by Scott Bradner and Jon Peterson.
