The server receives, from applications running on the endpoint devices, location updates identifying geographic locations of the endpoint devices. The server may modify a location database to include entries specifying the geographic locations of the endpoint devices. Data/telephone calls are routed based upon the entries specifying geographic locations of the plurality of endpoint devices. Based upon input parameters, a set of periodic update timings are generated and sent to the endpoint devices. ## Claims ### Claim 1 A system comprising: a data-communications server that is configured to provide data-communications services, including Voice over Internet Protocol (VoIP) services, to a plurality of data-communicative endpoint devices, the server including one or more computer processor circuits and memory circuits that are configured to provide the services to the plurality of endpoint devices by: receiving, at the server and from applications running on the plurality of endpoint devices, location updates identifying geographic locations of the plurality of endpoint devices;
