ENUM in a nutshell
ENUM is a new technology that links the world of telephony with the world of the Internet. By doing so, ENUM can revolutionise the way that individuals, businesses and other organisations communicate with one another.
More important than how ENUM works is what it can mean for you, the end user. With ENUM, all you need is someone's phone number to send them an e-mail or text message, to call them over the Internet or to visit their website. And vice versa: if someone has your phone number they can contact you through a variety channels. But only if you have chosen to make yourself contactable via those channels, and set things up accordingly.
The system opens up all sorts of possibilities. You can have your e-mail sent to your mobile while you're away. Or have incoming text messages delivered as e-mail. Thanks to ENUM, communication is no longer tied to any single location or mode.
You are in total control of the way you are contacted.
