Session Initiation Protocol for Telephones : Context and Architectures
RFC 3372, “Session Initiation Protocol for Telephones : Context and Architectures”, is a Best Current Practice document published in September 2002 by A. Vemuri, J. Peterson. The canonical text is published by the RFC Editor.
Abstract
The popularity of gateways that interwork between the PSTN (Public Switched Telephone Network) and SIP networks has motivated the publication of a set ofcommon practices that can assure consistent behavior across implementations. This document taxonomizes the uses of PSTN-SIP gateways, provides uses cases, and identifies mechanisms necessary for interworking. The mechanisms detail how SIP provides for both 'encapsulation' (carriage of PSTN signaling across a SIP network) and 'translation' (protocol mapping).
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
