The addressing scheme is one of the fundamental differences between traditional telephony and IP-based communication. While traditional telephony uses phone number to address endpoints on the public switched telephony network (PSTN), IP-based communication protocols use uniform resource identifiers (URLs) to address internet based endpoints. Typical examples for such URLs are:
For seamless convergence between traditional and IP-based communication, a mapping between phone numbers and URLs is needed. ENUM (Electronic Number Mapping) was developed to provide such a mapping between phone numbers and the respective URLs. For example the phone number of IPCom GmbH is linked to IPCom's web-, email and VoIP address (see ENUM-Lookup).
Therefore, ENUM is the addressing scheme link between the PSTN and IP-based communication services like VoIP. ENUM enables a common addressing, and allows to use phone numbers seamlessly for IP-based communication services.
