Technical Summary ENUM provides a way for a communication system to lookup a tel URI and see if alternative processing or routing can be applied to it. In some cases, such as when there is no entry in DNS for the ENUM lookup on that tel URI, each network element that processed the tel URI could end up repeating the lookup. This is inefficient. This specification defines an new "enumdi" parameter for the tel URI that indicates that an ENUM query has already been performed by a previous network element. This allows more efficient processing. Working Group Summary The working group reached consensus on this document. Protocol Quality This document received working group review over an extended period of time and was also reviewed by the ENUM WG. Alex Mayrhofer did a NITs review of the document.
