1. A system comprising:
- a location server configured to monitor a register message associated with an Internet Protocol (IP) device, wherein the register message includes a source IP address and a second IP address; and
a location database configured to store physical location information and a plurality of IP addresses associated with the IP device, wherein the location server determines whether at least one of the source IP address and the second IP address of a selected message corresponds with any of the plurality of IP addresses associated with the IP device;
acquires, based on the determination, physical location information corresponding to at least one of the source IP address and the second IP address; and
transmits a message using a number associated with the at least one of the source IP address and the second IP address, wherein the transmitted message requests the location of the IP device.

20. A method comprising:
-
providing a plurality of Internet Protocol (IP) addresses that have a stored association with an IP device; receiving a query for physical location information, wherein the query is a result of at least one of a source IP address and a second IP address, both of which are provided by a register message originating from the IP device, not corresponding with any of the plurality of IP addresses that have the stored association with the IP device and wherein the at least one of the source IP address and the second IP address are not associated with a current physical location information of the IP device; and indicating to a server that the current physical information of the IP device is unknown, wherein the indication notifies the server to transmit a message using a number associated with the at least one of the source IP address and the second IP address and wherein the transmitted message requests the location of the IP device.
