Let’s migrate to ENUM
The development of information technology and telecommunications makes more and more electronic services available. These services (SMS, MMS, e-mail, instant messaging) facilitate an advanced communication between users. MMS, e-mail, fax, etc. define points of presence of a user. These points can be reached via different addressing schemes. If someone wants to present all his/her contact information on the same phisical medium, it is quite inconvenient when one of these information changes. In this case all pieces of the business cards (for example) must be reprinted. Using ENUM, this problem can be solved – one should print only one identifier on the businiess card, that wouldn’t change over time. The question occurs, hovever: If ENUM is such useful, why is it not widely used? Present article tries to answer this question.
