Abstract

Methods and apparatus to measure market share for VoIP carriers is disclosed. An example method includes querying a plurality of VoIP carrier servers to determine the VoIP carrier server that owns the telephone subscriber number (SN), in response to the querying, receiving a plurality of messages operable to determine whether the telephone SN is found within any one of the plurality of VoIP carrier servers, when the received plurality of messages is at least one of inconclusive or when the telephone SN is not found within any one of the plurality of VoIP carrier servers, placing a first partial call to the telephone SN from a first VoIP number within a first VoIP carrier network, receiving a first signal from the first VoIP carrier network, and based on the first received signal, determining whether the telephone SN belongs to the first VoIP carrier network.

(4) in response to placing the partial call, determining whether the telephone subscriber number belongs to the selected VoIP carrier network based on a signaling parameter retrieved from the selected VoIP carrier network;

(5) repeating (3) and (4) for another selected VoIP carrier network when the telephone subscriber number does not belong to the selected VoIP carrier network;

(6) associating a VoIP carrier with the telephone subscriber number when the telephone subscriber number does belong to the selected VoIP carrier network;

(7) repeating (1) to (6) when a total number of telephone subscriber numbers queried is less than a sample size; and

(8) determining market share of a first VoIP carrier based on a first number of telephone subscriber numbers associated with the first VoIP carrier with respect to the sample size.

2. A method as defined in claim 1, further comprising:

in response to determining the telephone subscriber number is found within any one of the plurality of VoIP carrier servers, identifying a VoIP carrier server where the telephone subscriber number is found; and

associating the telephone subscriber number with a VoIP carrier corresponding to the identified VoIP carrier server.

3. A method as defined in claim 1, wherein determining the telephone subscriber number is not found within any one of the plurality of VoIP carrier servers includes obtaining an inconclusive message from the plurality of VoIP carrier servers.

4. A method as defined in claim 3, wherein the inconclusive message indicates at least one of an incorrect password or the telephone subscriber number is incorrect.

5. A method as defined in claim 1, wherein the signaling parameter corresponds to a period between placing the partial call and retrieving the signaling parameter.

6. A method as defined in claim 1, further comprising determining market share of a second VoIP carrier based on a second number of telephone subscriber numbers associated with the second VoIP carrier with respect to the sample size.

7. A method as defined in claim 1, wherein repeating (3) and (4) for another selected VoIP carrier network further comprises repeating the placing the partial call for a number of VoIP carriers until the telephone subscriber number is associated with a VoIP carrier.

8. A method as defined in claim 7, further comprising associating the telephone subscriber number with a group category when the telephone subscriber number is unassociated with a VoIP carrier after repeating the placing the partial call for the number of VoIP carriers.

9. An apparatus to estimate market share of a Voice Over Internet Protocol (VoIP) carrier, comprising:

a server query unit to;

query a plurality of VoIP carrier servers to determine the VoIP carrier server that owns a telephone subscriber number; and

obtain a plurality of messages in response to the querying; and

a processor to;

determine whether the telephone subscriber number is found within any one of the plurality of VoIP carrier servers or when the received plurality of messages is at least one of inconclusive or when the telephone subscriber number is not found within any one of the plurality of VoIP carrier servers;

cause a partial call initiator to place a partial call to the telephone subscriber number from a VoIP number within a first VoIP carrier network when the telephone subscriber number is not found within any one of the plurality of VoIP carrier servers;

determine whether the telephone subscriber number belongs to the first VoIP carrier network based on a signaling parameter retrieved from the first VoIP carrier network in response to placing the partial call;

cause the partial call initiator to place a partial call to the telephone subscriber number from a second VoIP number within a second VoIP carrier network when the telephone subscriber number does not belong to the first VoIP carrier network;

associate a corresponding VoIP carrier with the telephone subscriber number when the telephone subscriber number does belong to a VoIP carrier network; and

determine market share of a first VoIP carrier based on a first number of telephone subscriber numbers associated with the first VoIP carrier with respect to a total number of telephone subscriber numbers queried.

10. An apparatus as defined in claim 9, wherein the server query unit is to:

identify a VoIP carrier server in response to determining the telephone subscriber number is found within any one of the plurality of VoIP carrier servers; and

associate the telephone subscriber number with a VoIP carrier corresponding to the identified VoIP carrier server.

11. An apparatus as defined in claim 9, wherein the server query unit is to determine the telephone subscriber number is not found within any one of the plurality of VoIP carrier servers by obtaining an inconclusive message from the plurality of VoIP carrier servers, wherein the inconclusive message is indicative of at least one of an incorrect password or that the telephone subscriber number is incorrect.

12. An apparatus as defined in claim 9, wherein the signaling parameter is to correspond to a period between the partial call placement and the signaling parameter retrieval.

13. An apparatus as defined in claim 9, wherein the processor is to determine market share of a second VoIP carrier based on a second number of telephone subscriber numbers associated with the second VoIP carrier with respect to the total number of telephone subscriber numbers queried.

14. An apparatus as defined in claim 9, wherein the partial call initiator is to repeat placing the partial call for a number of VoIP carriers when the telephone subscriber number does not belong to the selected VoIP carrier network, the partial call initiator to repeat placing the partial call until the telephone subscriber number is associated with a VoIP carrier.

15. An apparatus as defined in claim 14, wherein the processor is to associate the telephone subscriber number with a group category when the telephone subscriber number is unassociated with a VoIP carrier after repeating the placing the partial call for the number of VoIP carriers.

16. A tangible machine readable storage device or storage disk comprising machine accessible instructions that, when executed, cause a machine to at least:

(1) query a plurality of VoIP carrier servers to determine the VoIP carrier server that owns a telephone subscriber number;

(2) in response to the querying, obtain a plurality of messages operable to determine whether the telephone subscriber number is found within any one of the plurality of VoIP carrier servers;
