  • Patent number: 9667802
    Abstract: An IP telephony system obtains control over a group of telephone numbers that can be assigned to its customers' telephony devices under a contract with a first local exchange carrier that originally controlled the group of telephone numbers. The first local exchange carrier assigns one or more location routing numbers to the group of telephone numbers, and the one or more location routing numbers are for the exclusive use of the IP telephony system. The one or more location routing numbers are then recorded against the group of telephone numbers in a local number portability database. Other exchange carriers are then caused to route calls directed to the any telephony number associated with the one or more location routing numbers directly to the IP telephony system. As a result, a second local exchange carrier can terminate telephony communications directly to the IP telephony system, bypassing the first local exchange carrier.

  • Patent number: 9407774
    Abstract: A temporary ENUM architecture assigns a temporary ENUM at call time. For an originated communication requiring routing to a party which needs a particular callback format not supported, the TempENUM provides consistency 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 that assigns a suitable TempENUM at the time of call routing, and a module that handles a lookup in the TempENUM database, and maps the assigned TempENUM to a calling party identifier (CgPID). The TempENUM database stores a TempENUM from a coordinator 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 the initial caller.

  • Patent number: 8891750
    Abstract: An automated method begins by receiving a list of numbers that have been de-activated by a carrier. Periodically, and for each number, a request is made to identify a current carrier for the number. If the current carrier matches the carrier that provided the de-activation information, the mobile number is considered to be in a first state, i.e., shut off and returned to a pool of numbers that are available to this same carrier. Upon a determination that the number is in the first state, the provider issues a request to any opt-in database to delete any express consent or other similar data associated with the number. If, however, the number does not match the carrier of deactivation, the number is considered to be in a second state, i.e., likely to have been ported by the same user to a new carrier. This state is logged in an audit trail.
