RFC2824 - Call Processing Language Framework and Requirements
This document describes an architectural framework we call a processing language, as a simple and standardized way for implementing and deploying Internet telephony. A large number of the services we wish to make possible for Internet telephony require fairly elaborate combinations of signalling operations, often in network devices, to complete. It also outlines requirements for such a language. This memo provides information for the Internet community.
RFC2871 - A Framework for Telephony Routing over IP
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.
RFC3219 - Telephony Routing over IP (TRIP)
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]
RFC3872 - Management Information Base for Telephony Routing over IP (TRIP)
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]
RFC3880 - Call Processing Language (CPL): A Language for User Control of Internet Telephony Services
This document defines the Call Processing Language (CPL), a language to describe and control Internet telephony services. It is designed to be implementable on either network servers or user agents. It is meant to be simple, extensible, easily edited by graphical clients, and independent of operating system or signalling protocol. It is suitable for running on a server where users may not be allowed to execute arbitrary programs, as it has no variables, loops, or ability to run external programs. [STANDARDS-TRACK]
RFC3966 - The tel URI for Telephone Numbers
This document specifies the URI (Uniform Resource Identifier) scheme "tel". The "tel" URI describes resources identified by telephone numbers. This document obsoletes RFC 2806. [STANDARDS-TRACK]
RFC4694 - Number Portability Parameters for the "tel" URI
This document defines five parameters in the "tel" Uniform Resource Identifier (URI) to carry the number portability (NP)-related information. Those parameters can be passed to the next-hop network node after an NP database dip has been performed. [STANDARDS-TRACK]
RFC4759 - The ENUM Dip Indicator Parameter for the "tel" URI
This document defines a new parameter "enumdi" for the "tel" Uniform Resource Identifier (URI) to support the handling of ENUM queries in Voice over Internet Protocol (VoIP) network elements. A VoIP network element may receive a URI containing an E.164 number, where that URI contains an "enumdi" parameter. The presence of the "enumdi" parameter indicates that an ENUM query has already been performed on the E.164 number by a previous VoIP network element. Equally, if a VoIP network element sends such a URI, it asserts that an ENUM query has been carried out on this number. [STANDARDS-TRACK]
RFC4904 - Representing Trunk Groups in tel/sip Uniform Resource Identifiers (URIs)
This document describes a standardized mechanism to convey trunk group parameters in sip and tel Uniform Resource Identifiers (URIs). An extension to the tel URI is defined for this purpose. [STANDARDS-TRACK]
RFC5140 - A Telephony Gateway REgistration Protocol (TGREP)
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]
RFC5341 - The Internet Assigned Number Authority (IANA) tel Uniform Resource Identifier (URI) Parameter Registry
This document creates an Internet Assigned Number Authority (IANA) registry for tel Uniform Resource Identifier (URI) parameters and their values. It populates the registry with the parameters defined in the tel URI specification, along with the parameters in tel URI extensions defined for number portability and trunk groups. [STANDARDS-TRACK]
