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.

This document is a product of the IP Telephony Working Goup of the
IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.

This announcement is sent to the IETF list and the RFC-DIST list.
Requests to be added to or deleted from the IETF distribution list
should be sent to IETF-REQUEST at IETF.ORG.  Requests to be
added to or deleted from the RFC-DIST distribution list should
be sent to RFC-DIST-REQUEST at RFC-EDITOR.ORG.
