Abstract

A system, method and non-transitory computer readable storage medium comprising instructions that when read by a processor perform receiving a telephony connection request at a location in a telephony network, the location separated from an intended recipient of the telephony connection request by a target telephony network, determining addressing information regarding the intended recipient, the addressing information including at least routing information or a phone number, determining a status characteristic of the intended recipient based on the addressing information, based on the status characteristic, and determining whether the intended recipient would successfully receive the telephony connection request if the telephony connection request was forwarded to the intended recipient.

First claim

What is claimed is:

1. A method, comprising:
receiving, from a sender, a telephony connection request at a location in a telephony network, the telephony connection request directed toward an intended recipient;
identifying a type of the sender and a type of the intended recipient;
identifying a compatibility of the sender and the intended recipient based on a comparison of the type of the sender and the type of the intended recipient;
determining a status characteristic of the intended recipient based on addressing information, wherein the status characteristic is based on active network registration; and
sending a spoofed reply to the sender based on the type of the sender and the type of the intended recipient being identified as incompatible.

2. The method of claim 1 , wherein the telephony connection request includes at least one of:
a fax telephony connection request and the intended recipient is not configured to receive faxes;
a voice telephony connection request and the intended recipient is not configured to receive voice calls; and
a text telephony connection request and the intended recipient is not configured to receive text messages.

3. The method of claim 1 , wherein the determining the status characteristic of the intended recipient includes at least one of:
determining whether a telephony number associated with the intended recipient is valid;
determining that the intended recipient is a wireless recipient;
determining whether the telephony number associated with the intended recipient is registered with a wireless network; and
determining whether a device associated with the intended recipient is active on the wireless network.

4. The method of claim 3 , wherein the determining whether a telephony number associated with the intended recipient is valid includes accessing a line information database using the telephony number.

5. The method of claim 1 , further comprising,
sending a reply in response to the telephony connection request, wherein:
forwarding the telephony connection request to the intended recipient would result in a system response; and
the reply differs from the system response.

6. The method of claim 1 , further comprising at least one of:
forwarding the received telephony connection request; and
denying the received telephony connection request.

7. A non-transitory computer readable storage medium comprising instructions that when read by a processor cause the processor to perform:
receiving, from a sender, a telephony connection request at a location in a telephony network, the telephony connection request directed toward an intended recipient;
identifying a type of the sender and a type of the intended recipient;
identifying a compatibility of the sender and the intended recipient based on a comparison of the type of the sender and the type of the intended recipient;
determining a status characteristic of the intended recipient based on addressing information, wherein the status characteristic is based on active network registration; and
sending a spoofed reply to the sender based on the type of the sender and the type of the intended recipient being identified as incompatible.

8. The non-transitory computer readable storage medium of claim 7 , wherein the telephony connection request includes at least one of:
a fax telephony connection request and the intended recipient is not configured to receive faxes;
a voice telephony connection request and the intended recipient is not configured to receive voice calls; and
a text telephony connection request and the intended recipient is not configured to receive text messages.

9. The non-transitory computer readable storage medium of claim 7 , wherein the determining the status characteristic of the intended recipient includes at least one of:
determining whether a telephony number associated with the intended recipient is valid;
determining that the intended recipient is a wireless recipient;
determining whether the telephony number associated with the intended recipient is registered with a wireless network; and
determining whether a device associated with the intended recipient is active on the wireless network.

10. The non-transitory computer readable storage medium of claim 9 , wherein the determining whether a telephony number associated with the intended recipient is valid includes accessing a line information database using the telephony number.

11. The non-transitory computer readable storage medium of claim 7 , comprising instructions that when read by the processor cause the processor to perform:
sending a reply in response to the telephony connection request, wherein:
forwarding the telephony connection request to the intended recipient would result in a system response; and
the reply differs from the system response.

12. The non-transitory computer readable storage medium of claim 7 , comprising instructions that when read by the processor cause the processor to perform at least one of:
forwarding the received telephony connection request; and
denying the received telephony connection request.

13. A system, comprising:
a processor; and
a memory storing instructions that when executed by the processor cause the processor to:
receive, from a sender, a telephony connection request at a location in a telephony network, the telephony connection request directed toward an intended recipient;
identify a type of the sender and a type of the intended recipient;
identify a compatibility of the sender and the intended recipient based on a comparison of the type of the sender and the type of the intended recipient;
determine a status characteristic of the intended recipient based on addressing information, wherein the status characteristic is based on active network registration; and
send a spoofed reply to the sender based on the type of the sender and the type of the intended recipient being identified as incompatible.

14. The system of claim 13 , wherein the telephony connection request includes at least one of:
a fax telephony connection request and the intended recipient is not configured to receive faxes;
a voice telephony connection request and the intended recipient is not configured to receive voice calls; and
a text telephony connection request and the intended recipient is not configured to receive text messages.

15. The system of claim 13 , wherein the determination of the status characteristic of the intended recipient status characteristic includes at least one of:
a determination whether a telephony number associated with the intended recipient is valid;
a determination that the intended recipient is a wireless recipient;
a determination whether the telephony number associated with the intended recipient is registered with a wireless network; and
a determination whether a device associated with the intended recipient is active on the wireless network.

16. The system of claim 15 , wherein the determination whether a telephony number associated with the intended recipient is valid includes accessing a line information data base using the telephony number.

17. The system of claim 13 , wherein the processor is to:
send sends a reply in response to the telephony connection request, wherein:
the telephony connection request forwarded to the intended recipient would result in a system response; and
the reply differs from the system response.
