Patent ID: 8862109

Claim:
A method for canceling call forwarding instructions that have previously been implemented by a native telephony service provider that provides a telephony device with its native telephony service, the telephony device having a native telephone number, where the call forwarding instructions resulted in incoming telephony communications directed to the native telephone number being directed to a forwarding access number, the method comprising: determining whether previously implemented call forwarding instructions for the telephony device should be canceled, wherein the determining step is performed by at least one processor of a computing device; and causing, when the previously implemented call forwarding instructions should be canceled, the native telephony service provider to cancel the previously implemented call forwarding instructions such that incoming telephony communications directed to the native telephone number are no longer directed to the forwarding access number and are instead routed to the native telephone number by: determining a character string that can be dialed from the telephony device to cause the native telephony service provider to cancel the call forwarding instructions; and providing the determined character string to the telephony device.
