The goal of ENUM is to make available different addresses, numbers and URL's under one single number.
In this way, the private home telephone, the work telephone, the fax number, cell phone numbers, business and private E-Mail addresses, video conference addresses, personal website and all other conceivable communication addresses can be summarized under one single ENUM number.
Depending on whatever application is currently being used (e.g. telephone, E-Mail program etc.) this searches under the given ENUM number for the actual target address.
