本文介绍了一种用于统一电话号码系统E.164与互联网地址系统DNS的技术——ENUM。通过使用间接查找方法，ENUM能够实现从IP和PSTN网络拨打VoIP用户的便利。尽管如此，ENUM并非VoIP功能，不应将其与基于SIP、H.323或IAX等协议的常见VoIP路由混淆。

Telephone Number Mapping (ENUM or Enum, from TElephone NUmber Mapping) is a suite of protocols to unify the telephone numbering system E.164 with the Internet addressing system DNS by using an indirect lookup method, to obtain NAPTR records. The records are stored at a DNS database.

Although it facilitates calling VoIP users from IP and PSTN networks, ENUM is not a VoIP function and should not be confused with common VoIP routing based on SIP, H.323 or IAX protocols with a Uniform Resource Identifier (URI).
