Patent attributes
In one example, a Voice over Internet Protocol (VoIP) endpoint device such as a smart phone or other CPU device interfaces with a data communications server which provides VoIP services to a plurality of VoIP-capable endpoint devices. The VoIP endpoint device includes at least one computer processor circuit and memory circuit that are configured to obtain current geolocation data. The VoIP endpoint device retrieves previously-reported geolocation data from the memory circuit and determines, based upon the previously-reported geolocation data and the current geolocation data, that a mismatch trigger event has occurred. The VoIP endpoint device sends, in response to the determining, the current geolocation data from the particular endpoint device to the VoIP server. The current geolocation data is stored in the memory circuit.
