Abstract
The present invention includes a system and method for using Local Area Network (LAN) switch information of an internet protocol phone to determine the location of the internet protocol phone. The internet protocol phone communicates with a server and receives a dynamic internet protocol address. The internet protocol phone further communicates with a second server to receive LAN switch information for the internet protocol phone. The internet protocol phone transmits the dynamic internet protocol address and LAN switch information to a phone management module. The phone management module queries a LAN switch in order to gather further LAN switch information for the internet protocol phone. The phone management module transmits the dynamic internet protocol address and LAN switch information to a third party in order to more accurately determine the location of a user using the internet protocol phone.
