TEMPORARY ENUM GATEWAY Russian patent published in 2011 - IPC H04M7/00 

FIELD: information technology.

SUBSTANCE: temporary ENUM architecture assigns a temporary ENUM at call time. For the arising communication requiring routing to a party which needs a particular callback format not supported, the TempENUM provides compatibility with the specific format required by the receiving party. The TempENUM is assigned for the duration of the call or communication, or for a given amount of time thereafter. The TempENUM service gateway includes a TempENUM database, a module which assigns a suitable TempENUM at the time of call routing, and a module which handles search in the TempENUM database, and maps the assigned TempENUM to a calling party identifier (CgPID). The TempENUM database stores a TempENUM from a coordination system and relates the actual calling party identifier (CgPID) for use in callback attempts. Either during the initial call or communication, or shortly thereafter, the receiving party uses the TempENUM number to return communication to the initial caller.

EFFECT: high reliability of providing information on callback number.
