ANI based routing
First Claim
Patent Images
1. A method of routing calls, comprising the steps of:
- receiving a code indicative of the calling party in a switch controlled by a first carrier;
passing said code to an external database engine coupled to said switch;
determining an identity of a second carrier based on said code;
retrieving routing information based on said identity of said second carrier in said database engine;
sending said routing information to said switch.

Abstract
An ISP 10 provides enhanced features compatible with non-AIN switches to allow service providers to provide customers with features such as voice prompting, DTMF number collection, fax on demand and similar features. In one embodiment, the ISP can also be configured as an IP. Enhanced features can be accomplished using the ISP, such as advanced routing of long distance calls based on ANI, authorization codes, type of call, time of day, origination of call and destination of call.

determining the identity of the second carrier based on an automatic number identification associated with the calling party. -
4. The method of claim 1 wherein said step of retrieving routing information comprises the step of retrieving routing information responsive to said identity of the second carrier and to type of call information.
-
5. The method of claim 4 wherein said type of call is from a set of call types including direct dial, operator, operator assisted, international direct dial and operated assisted international direct dial call types.
-
6. The method of claim 1 wherein said step of retrieving routing information comprises the step of retrieving routing information responsive to said identity of the second carrier and to a called number.
-
7. The method of claim 6 wherein said retrieving step comprises the step of retrieving routing information based on said identity of said second carrier and a predetermined set of digits in said called number.
-
8. The call control circuitry of claim 6 wherein said external database engine comprises circuitry for retrieving routing information based on said identity of said second carrier and a predetermined set of digits in said called number.
-
9. The method of claim 1 wherein said step of retrieving routing information comprises the step of retrieving routing information responsive to said the identity of said second carrier and to time of day information.
-
10. The method of claim 1 wherein said retrieving step comprises the step of retrieving routing information based on said identity of said second carrier and an identifier associated with said switch.
-
11. The method of claim 1 and further comprising the step of inhibiting calls to one or more numbers associated with said code.
-
-
12. Call control circuitry, comprising:
-
a switch controlled by a first carrier for receiving calling information including a code indicative of a calling party;
an external database engine coupled to said switch for receiving said calling information, determining an identity of a second carrier based on said code, and retrieving routing information based on identity of said second carrier;
circuitry for routing the call based on the routing information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
