8X8 Gets Virtual Telephone Extension Patent, "A method for routing telephone calls to communication devices using telephone networks"

8X8 Gets Virtual Telephone Extension Patent http://snapvoip.blogspot.com
This is the second time I am mentioning USPTO, as I just read that it has awarded a patent for Virtual Telephone Extension to 8X8.

"A method for routing telephone calls to communication devices using telephone networks, each communication device having a unique device identifier, the method comprising: assigning identifier data to each of a plurality of users, the identifier data for each user including at least two unique telephone numbers and at least one unique device identifier; and in response to receiving a call through one of the telephone networks, matching a telephone number in the call with one of the at least two telephone numbers assigned to a particular user, and switching the call to a destination communication device designated by the device identifier in the identifier data for the particular user."

But the funny thing is, Andy Abramson alerted that it looks very similar to the patent issued to Vonage for Virtual Numbers, "Method and Apparatus for Placing a Long Distance Call Based on a Virtual Phone Number," a few days ago, 
I am begining to love USPTO, by issuing multiple patents for the same method or product, sueing will take a different path, perhaps they will sue USPTO?
