Abstract

A system and method for routing calls based on the different fee structure between voice and data is disclosed. The origination type for an incoming call is determined. When the incoming call is a VoIP call then the call is routed based, in part, on selecting the minimum fee required to terminate the call.

Claims

1. A method of call routing, the method comprising:

receiving an incoming call in a switch;

determining whether or not an origination type for the call is voice over internet protocol (VoIP);

when the origination type is VoIP then;

determining a numbering plan area (NPA) for a destination number;

when the destination number NPA comprises a predetermined NPA then routing the call to a local exchange carrier (LEC) through a competitive local exchange carrier (CLEC);

when the destination number NPA does not comprise a predetermined NPA then routing the call to the LEC without routing through the CLEC; and

when the origination type is not VoIP then terminating the call to the LEC without routing through the CLEC.

2. The method of claim 1 further comprising:

when the call is a local call then routing the call directly through the LEC without routing through the CLEC.

3. The method of claim 1 where there are a plurality of predetermined NPA'"'"'s.

4. The method of claim 1 where the predetermined NPA indicates an intra-state call.

5. The method of claim 1 further comprising:

first determining if the incoming call is a 1+ call;

when the incoming call is not a 1+ call then routing the call using the LEC.

6. An apparatus, comprising:

a switch;

a service control point (SCP);

the switch is configured to detect an incoming call, determine whether or not an origination type for the call is voice over internet protocol (VoIP), and when the origination type for the call is not VoIP, terminate the call to a local exchange carrier (LEC) without routing through a competitive local exchange carrier (CLEC);

the switch is configured to, when the origination type for the call is VoIP, transfer a query for delivery to the SCP for routing instructions for the call;

the SCP is configured to, in response to the query, determine whether a destination number of the call comprises a predetermined destination number;

the SCP is configured to, when the destination number comprises the predetermined destination number, determine the routing instructions to route the call to the LEC through the CLEC;

the SCP is configured to, when the destination number does not comprise the predetermined destination number, determine the routing instructions to route the call to the LEC without routing through the CLEC; and

the switch is configured to receive the routing instructions in response to the query and route the call based on the routing instructions.

7. The apparatus of claim 6 where the predetermined destination number indicates an intra-state call.

8. The apparatus of claim 6 where the switch is a soft switch.

9. The apparatus of claim 6 where the SCP uses only part of the destination number when determining whether the destination number comprises the predetermined destination number.

10. The apparatus of claim 9 where only a prefix of the destination number is used when determining whether the destination number comprises the predetermined destination number.

11. The apparatus of claim 9 where only an area code of the destination number is used when determining whether the destination number comprises the predetermined destination number.

12. An apparatus, comprising:

a switch;

a service control point (SCP);

the switch configured to detect an incoming call, determine whether or nor if the incoming call comprises a 1+ call, and when the call does not comprise the 1+ call, terminate the call to a local exchange carrier (LEC) without routing through a competitive local exchange carrier (CLEC);

the switch configured to, when the call comprises the 1+ call, determine whether or not an origination type for the call is voice internet protocol (VoIP), and when the origination type for the call is not VoIP terminate the call to the LEC without routing through the CLEC;

the switch configured to, when the origination type for the call is VoIP, transfer a query for delivery to the SCP for routing instructions for the call;

the SCP configured to, in response to the query, determine whether a numbering plan area (NPA) for a destination number of the call comprises a predetermined NPA;

the SCP configured to, when the destination number NPA comprises the predetermined NPA, determine the routing instructions to route the call to the LEC through the CLEC;

the SCP configured to, when the destination number NPA does not comprise the predetermined NPA, determine the routing instructions to route the call to the LEC without routing through the CLEC; and

the switch configured to receive the routing instructions in response to the query and route the call based on the routing instructions.

13. The apparatus of claim 12 where the predetermined NPA indicates a reduced cost for terminating the call based on both an equipment cost for routing the call and a lowest available legal regulatory termination fee.

14. The method of claim 12 where the predetermined NPA indicates an intra-state call.
