Abstract

In some embodiments, a do not redirect or reject call management system may include one or more of the following features: (a) a memory comprising, (i) a do not redirect or reject application that allows a caller to prevent a call recipient from redirecting or rejecting a call, and (b) a processor coupled to the memory that executes the do not redirect or reject application.

Claims

1. A do not redirect or reject call management system comprising:

a memory comprising;

a do not redirect or reject application that allows a caller to prevent a call recipient from redirecting or rejecting a call; and

a processor coupled to the memory that executes the do not redirect or reject application, the call being placed on a SIP network, wherein the application determines if a redirect recipient is reachable, if the redirect recipient is unreachable, the application instructs a call recipient'"'"'s phone to answer the call, if the redirect recipient is reachable, the application routes the call to the redirect recipient.

6. The system of claim 1, wherein a do not redirect or reject instruction is present in a call request.

7. The system of claim 6, wherein the do not redirect or reject instruction is within a SIP header.

2-5. -5. (canceled)

8. A method for preventing calls from being redirected or rejected, the method comprising the steps of:

initiating a call to a recipient having do not redirect or reject instructions;

routing the call through an SIP network;

receiving redirect or reject instructions from a recipient'"'"'s phone;

determining if a redirect recipient is available to take a redirected call;

redirecting the call if the redirect recipient is available; and

instructing the recipient'"'"'s phone that it must accept the call if the redirect recipient is unavailable based upon the do not redirect or reject instructions.

13. The method of claim 8, further comprising the step of sending the call directly to the recipient and instructing the recipient to answer the call based on a caller'"'"'s priority or seniority.

9-12. -12. (canceled)

14. A machine readable medium comprising machine executable instructions, including:

call instructions that route a call to a recipient, the call occurring over a SIP network;

redirect instructions that determine if the recipient has a redirect or reject instructions on their phone; and

do not redirect or reject instructions that override the redirect or reject instructions to route the call to the recipient, wherein the do not redirect or reject instructions determine if a redirect recipient is available to receive the call, the do not redirect or reject instructions route the call to the redirect recipient if the redirect recipient is available and the do not redirect or reject instructions force a recipient'"'"'s oh one to accept the call if the redirect recipient is not available.

20. The medium of claim 14, wherein the do not redirect or reject instructions place a do not redirect or reject command in an SIP header.

15. (canceled)

16. The medium of claim 15, wherein the call is made from a SIP enabled device.
