Abstract

A method for communicating media based on location of media source includes receiving communications from a plurality of endpoints. Each communication comprises a media message and location information identifying a location of its transmitting endpoint. The method includes receiving a selection of a geographical area and comparing the location information of each communication with the selected geographical area. The method also includes presenting to a user each message received from each endpoint of the plurality of endpoints located within the selected geographical area.
