A Telephony Gateway REgistration Protocol
RFC 5140, “A Telephony Gateway REgistration Protocol”, is a Proposed Standard document published in March 2008 by M. Bangalore, R. Kumar, J. Rosenberg, H. Salama, D.N. Shah. The canonical text is published by the RFC Editor.
Abstract
This document describes the Telephony Gateway Registration Protocol (TGREP) for registration of telephony prefixes supported by telephony gateways and soft switches. The registration mechanism can also be used to export resource information. The prefix and resource information can then be passed on to a Telephony Routing over IP (TRIP) Location Server, which in turn can propagate that routing information within and between Internet Telephony Administrative Domains (ITADs). TGREP shares a lot of similarities with the TRIP protocol. It has similar procedures and finite state machine for session establishment. It also shares the same format for messages and a subset of attributes with TRIP. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
