  "abstract": "The popularity of gateways that interwork between the PSTN (Public\r\nSwitched Telephone Network) and SIP networks has motivated the\r\npublication of a set ofcommon practices that can assure consistent\r\nbehavior across implementations.  This document taxonomizes the uses\r\nof PSTN-SIP gateways, provides uses  cases, and identifies mechanisms\r\nnecessary for interworking.  The mechanisms detail how SIP provides\r\nfor both 'encapsulation' (carriage of PSTN signaling across a SIP\r\nnetwork) and 'translation' (protocol mapping).",
