Method and system for processing interactive voice response input in a call setup message

1. A computer-implemented method for processing interactive voice response (IVR) input in a call setup request, comprising:

receiving at an IVR system a call setup message including information associated with one or more data fields;

parsing the information included in the call setup message; and

directing a call based solely on the information included in the call setup message.

2. The method of claim 1 , further comprising transmitting a message including one or more data fields that are accepted by the IVR system.

3. The method of claim 1 , wherein directing comprises routing the call through one or more IVR menus of the IVR system.

4. The method of claim 1 , wherein the information associated with the one or more data fields is received in one or more headers of the call setup message.

5. The method of claim 1 , wherein the data fields include at least one of a location, a personal identification number (PIN), a telephone extension, a user name, a conference PIN, credit card information, a telephone number to which a call can be returned, a zip code, an area code, an account number, or one or more answers to security questions.

6. The method of claim 1 , further comprising:

identifying additional information required by the IVR system to route the call;

sending a request for the additional information;

receiving the additional information;

parsing the additional information; and

further directing the call based on the additional information.

7. The method of claim 6 , wherein the additional information is provided by a user.

8. The method of claim 6 , further comprising receiving the additional information in one of a SIP INVITE, SIP UPDATE, SIP NOTIFY, or SIP INFO message.

9. A system for processing interactive voice response (IVR) input in a call setup message, comprising:

a header parser configured to receive at an IVR system a call setup message including information associated with one or more data fields; and parse the information included in the call setup message; and

a call router configured to direct a call based solely on the information included in the call setup message.

10. The system of claim 9 , further comprising a field publisher configured to transmit a message including one or more data fields that are accepted by the IVR system.

11. The system of claim 9 , wherein directing comprises routing the call through one or more IVR menus of the IVR system.

12. The system of claim 9 , wherein the information associated with one or more data fields is received in one or more headers of the call setup message.

13. The system of claim 9 , wherein the data fields include at least one of a location, a personal identification number (PIN), a telephone extension, a user name, a conference PIN, credit card information, a telephone number to which a call can be returned, a zip code, an area code, an account number, or one or more answers to security questions.

14. The system of claim 9 , further comprising an information requestor configured to

identify additional information required by the IVR system to route the call;

send a request for the additional information

receive the additional information;

parse the additional information; and

further direct the call based on the additional information.

15. The system of claim 14 , wherein the additional information is received in one of a SIP INVITE, SIP UPDATE, SIP NOTIFY, or SIP INFO message.
