enumdi: Supporting ENUM Queries in VoIP Network Elements

This document defines a new parameter "enumdi" in the "tel" URI to support handling ENUM queries in SIP proxies, H.323 gatekeepers, and other VoIP network elements. The presence of the "enumdi" parameter indicates that an ENUM query has already been performed on the E.164 number indicated.

  2. Abstract • This document defines a new parameter "enumdi" in the "tel" Uniform Resource Identifier (URI) as defined in RFC3966 to support the handling of ENUM queries in SIP proxies, H.323 gatekeepers and other VoIP network elements. • The presence of the "enumdi" parameter indicates to the VoIP network element receiving an URI containing an E.164 number that an ENUM query as defined in RFC3761 has already been performed on the E.164 number indicated by the previous VoIP network element. Richard Stastny

  3. Formal Syntax • The following syntax specification uses the augmented Backus-Naur Form (BNF) as described in RFC2234. enumdi = *1(enum-dip-indicator) enum-dip-indicator = ";enumdi" The "enum-dip-indicator" can appear in the "tel" URI at most once. Richard Stastny

  4. changed • from draft-stastny-iptel-enumdi-00 • Minor edits • If a VoIP network element receives a "tel" URI containing the "enumdi" parameter, the VoIP network element SHOULD NOT retrieve the related information for this number from ENUM in e164.arpa even if it would normally do so. • Changed domain in examples from:provider.net to example.com Richard Stastny
