BCPs are stable identifiers for Best Current Practices. A BCP may consist of a single RFC or a group of RFCs related to a specific IETF process or recommended guidelines. The collection may become empty as the BCP evolves.

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).
