The videoconferencing endpoint searches a location database using an identity of the callee provided by the caller, where the location database can store dialing information of a videoconferencing endpoint where the callee is known to be located. The videoconferencing endpoint can collect biometric data from a user and determine the identity of the user by matching the collected biometric data to biometric data stored in a biometric database. If a match is found, the videoconferencing endpoint updates the location database such that the location database indicates the videoconferencing endpoint as the current location of the user. ## Claims ### Claim 1 A method comprising: receiving, using a first videoconferencing endpoint from amongst a plurality of videoconferencing endpoints, first biometric data corresponding to a callee;
