Third party call control application program interface
View Patent ↗A third party call control (3PCC) application program interface (API) permits for users to use a web browser or other Internet capable software to place a call. The third party call control application program interface includes a first uniform resource locator operable over the Internet to effect a call between first and telephonic devices to be completed. The first uniform resource locator includes identification of the first telephonic device and identification of the second telephonic device.
1. A computer-implemented method of telephone call completion comprising:
(a) receiving a uniform resource locator (URL) including call setup information having an indication of a telephone call to be completed from a first telephonic device to a second telephonic device, wherein the call setup information includes an identification of the first telephonic device and an identification of the second telephonic device;
(b) initiating a call to the first telephonic device or the second telephonic device using a session initiation protocol (SIP) INVITE method and the received call setup information; and
(c) transferring the call using a SIP REFER method and the received call setup information in response to an answer of the call to establish the telephone call from the first telephonic device to the second telephonic device.
2. The computer-implemented method of claim 1 , wherein at least one of the identification of the first telephonic device or the identification of the second telephonic device comprises a telephone number.
3. The computer-implemented method of claim 1 , wherein the indication of the telephone call to be completed comprises at least one telephone number selected from among a plurality of telephone numbers.
4. The computer-implemented method of claim 1 , wherein the URL is generated from a selection of contact information relating to the telephone call to be completed.
5. The computer-implemented method of claim 4 , wherein the contact information relating to the telephone call that may be completed includes a telephone number.
6. The computer-implemented method of claim 4 , wherein the contact information includes information relating to a plurality of telephone calls.
7. The computer-implemented method of claim 6 , wherein the indication of the telephone call to be completed includes information relating to at least one of the plurality of telephone calls.
8. The computer-implemented method of claim 7 , wherein the information relating to the plurality of telephone calls includes a plurality of telephone numbers.
9. The computer-implemented method of claim 7 , wherein at least one of the identification of the first telephonic device or the identification of the second telephonic device includes the at least one telephone number.
10. A non-transitory machine-readable medium having machine-executable instructions stored thereon, which when executed by a machine or computer cause the machine or computer to perform a method, the method comprising:
(a) receiving a uniform resource locator (URL) including call setup information having an indication of a telephone call to be completed from a first telephonic device to a second telephonic device, wherein the call setup information includes an identification of the first telephonic device and an identification of the second telephonic device;
(b) initiating a call to the first telephonic device or the second telephonic device using a session initiation protocol (SIP) INVITE method and the received call setup information; and
(c) transferring the call using a SIP REFER method in response to an answer of the call to establish the telephone call from the first telephonic device to the second telephonic device and the received call setup information.
11. The non-transitory machine-readable medium of claim 10 , wherein at least one of the identification of the first telephonic device or the identification of the second telephonic device comprises a telephone number.
12. The non-transitory machine-readable medium of claim 10 , wherein the indication of the telephone call to be completed comprises at least one telephone number selected from among a plurality of telephone numbers.
13. The non-transitory machine-readable medium of claim 10 , wherein the URL is generated from a selection of contact information relating to the telephone call to be completed.
14. The non-transitory machine-readable medium of claim 13 , wherein the contact information relating to the telephone call that may be completed includes a telephone number.
15. The non-transitory machine-readable medium of claim 13 , wherein the contact information includes information relating to a plurality of telephone calls.
16. The non-transitory machine-readable medium of claim 15 , wherein the indication of the telephone call to be completed includes information relating to at least one of the plurality of telephone calls.
17. The non-transitory machine-readable medium of claim 16 , wherein the information relating to the plurality of telephone calls includes a plurality of telephone numbers.
18. The non-transitory machine-readable medium of claim 16 , wherein at least one of the identification of the first telephonic device or the identification of the second telephonic device includes the at least one telephone number.
19. A computer-implemented method of telephone call completion comprising:
(a) receiving a uniform resource locator (URL) including call setup information having an indication of the telephone call to be completed from a first telephonic device to a second telephonic device, wherein the call setup information includes an identification of the first telephonic device and an identification of the second telephonic device;
(b) initiating a call to the first telephonic device or the second telephonic device using a session initiation protocol (SIP) INVITE method and the received call setup information;
(c) transferring the call using a SIP REFER method and the received call setup information in response to an answer of the call to establish the telephone call from the first telephonic device to the second telephonic device; and
(d) billing the telephone call to an appropriate account, wherein billing information is derived from a “bill to” number supplied in the URL.
20. The computer-implemented method of claim 19 , wherein billing information is further derived from information consisting of a “from” number and a “to” number.
