TRIP

This memo updates the IANA registry rules for the Telephony Routing over IP (TRIP) protocol, by no longer requiring that postal addresses be included in contact information.

This memo updates RFC 3219.

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]

This document defines a new attribute for the Telephony Routing over IP (TRIP) protocol. The attribute associates protocols/services in the PSTN offering authorized prioritization during call setup that are reachable through a TRIP gateway. Current examples of preferential service in the Public Switched Telephone Network (PSTN) are Government Emergency Telecommunications Service (GETS) in the U.S. and Government Telephone Preference Scheme (GTPS) in the U.K. The proposed attribute for TRIP is based on the NameSpace.Value tuple defined for the SIP Resource-Priority field.

This memo defines a portion of the Management Information Base (MIB) module for use with network management protocols in the Internet community. In particular, it describes a set of managed objects that are used to manage Telephony Routing over IP (TRIP) devices. [STANDARDS-TRACK]

This document presents the Telephony Routing over IP (TRIP). TRIP is a policy driven inter-administrative domain protocol for advertising the reachability of telephony destinations between location servers, and for advertising attributes of the routes to those destinations. TRIP's operation is independent of any signaling protocol, hence TRIP can serve as the telephony routing protocol for any signaling protocol. [STANDARDS-TRACK]

This document serves as a framework for Telephony Routing over IP (TRIP), which supports the discovery and exchange of IP telephony gateway routing tables between providers. This memo provides information for the Internet community.
