Abstract

Methods, devices, and storage media provide for receiving a message pertaining to a telephone call set-up; identifying in the message a called telephone number; selecting a calling telephone number based on the called telephone number; replacing a calling telephone number included in the message with the selected calling telephone number; and transmitting the message that includes the selected calling telephone number.

Claims

1. A method comprising:

receiving, by a network device, a message pertaining to a telephone call set-up;

identifying in the message, by the network device, a called telephone number;

selecting, by the network device, a calling telephone number based on the called telephone number;

replacing, by the network device, a calling telephone number included in the message with the selected calling telephone number; and

transmitting, by the network device, the message that includes the selected calling telephone number.

2. The method of claim 1, further comprising:

selecting a billing telephone number based on the called telephone number; and

inserting the billing telephone number in the message.

3. The method of claim 1, wherein the selecting includes:

generating billing information based on the billing telephone number.

4. The method of claim 1, wherein the message includes a Session Initiation Protocol invite message.

5. The method of claim 1, further comprising:

generating billing information based on the selected calling telephone number.

6. The method of claim 1, wherein the calling telephone number has an area code that is different from an area code of the selected calling telephone number.

7. The method of claim 1, wherein the selected calling telephone number has an area code that is the same as an area code of the called telephone number.

8. A device comprising:

a communication interface;

one or more memories that store instructions; and

one or more processors to execute the instructions to;

receive, via the communication interface, a message pertaining to a telephone call set-up;

identify a called telephone number included in the message;

select a calling telephone number based on the called telephone number;

replace a calling telephone number included in the message with the selected calling telephone number; and

transmit, via the communication interface, the message that includes the selected calling telephone number.

9. The device of claim 8, wherein the one or more processors further execute the instructions to:

select a billing telephone number based on the called telephone number; and

insert the billing telephone number in the message.

10. The device of claim 9, wherein the one or more processors further execute the instructions to:

determine whether the message includes a Diversion header; and

11. The device of claim 8, further comprising:

a database that maps a portion of the called telephone number to the selected telephone number,

wherein the one or more processors further execute the instructions to;

use the database to select the calling telephone number.

12. The device of claim 11, wherein the message includes a Session Initiation Protocol invite message.

13. The device of claim 8, wherein the one or more processors further execute the instructions to:

generate billing information based on the selected calling telephone number; and

transmit, via the communication interface, to a billing device.

14. The device of claim 8, wherein the calling telephone number has an area code that is different from an area code of the selected calling telephone number.

15. The device of claim 14, wherein the selected calling telephone number has an area code that is the same as the area code of the called telephone number.

16. The device of claim 14, comprising an application server that provides a Session Initiation Protocol trunking service for Voice over Internet Protocol (VoIP).

17. A non-transitory storage medium storing instructions executable by a computational device to:

receive a message pertaining to a telephone call set-up;

identify a called telephone number included in the message;

select a calling telephone number based on the called telephone number;

replace a calling telephone number included in the message with the selected calling telephone number; and

transmit the message that includes the selected calling telephone number.

18. The non-transitory storage medium of claim 17, wherein the calling telephone number has an area code that is different from an area code of the selected calling telephone number.

19. The non-transitory storage medium of claim 17, further storing instructions executable by the computational device to:

select a billing telephone number based on the called telephone number; and

insert the billing telephone number in the message.

20. A method comprising:

receiving, by a network device, a message pertaining to setting up a telephone call;

identifying, by the network device, a called telephone number in the message;

identifying, by the network device, a format of the message;

selecting, by the network device, a calling telephone number based on the called telephone number or a calling telephone number and a billing telephone number based on the called telephone number, in response to identifying the format;

replacing, by the network device, a calling telephone number included in the message with the selected calling telephone number or with the selected calling telephone number and the selected billing telephone number; and

transmitting, by the network device, the message that includes the selected calling telephone number or the selected calling telephone number and the selected billing telephone number.
