The IMG supports ENUM E2U+sip to resolve an ENUM telephone number into a SIP URI.  With ENUM native SIP users, even at different VoIP service providers, can call each other directly without ever touching a PSTN service which can result in faster connection times and lower phone charges.

ENUM facilitates the interconnection of systems that rely on telephone numbers with those that use URIs to route transactions. E.164 is the ITU-T standard international numbering plan, under which all globally-reachable telephone numbers are organized.
