Distributed Call Signaling is a set of proposals by the PacketCable Consortium for extending SIP:

DCS draft May 2000.

Architectural Considerations for Providing Carrier Class Telephony Services Utilizing SIP-based Distributed Call Control Mechanisms

W. Marshall et al.
March 2001.

This document provides an overview of a SIP-based Distributed Call Signaling (DCS) architecture to support carrier class packet-based voice, video, and other real time multimedia services. Companion documents address a specific set of SIP 2.0 protocol extensions and usage rules that are necessary to implement the DCS architecture in an interoperable fashion.

SIP proxy-to-proxy extensions for supporting Distributed Call State

W. Marshall et al.
November 2000

In order to deploy a residential telephone service at very large scale across different domains, it is necessary for trusted elements owned by different service providers to exchange trusted information that conveys customer-specific information and expectations about the parties involved in the call. This document describes extensions to the Session Initiation Protocol (RFC2543) for supporting the exchange of customer information and billing information between trusted entities in the architecture described in (draft-dcsgroup- sip-arch-00.txt).
