Z-axis information for voice over Internet Protocol (VoIP)

A method, comprising:

• receiving, by a voice over Internet protocol (“VoIP”) telephone and from a computing system, a first z-axis data signal containing first z-axis data corresponding to a location of the computing system that is proximate to a current location of the VoIP telephone, based on z-axis data obtained from a z-axis data source associated with the computing system;
• when a VoIP connection has been established with a 911 or E911 address database system over a network, sending, by the VoIP telephone and to the 911 or E911 address database system, a second z-axis data signal containing the first z-axis data that is extracted from the first z-axis data signal;
• receiving, by the VoIP telephone and from the 911 or E911 address database system, a confirmation signal including second z-axis data;
• and
• sending, by the VoIP telephone and to the computing system, the confirmation signal for comparing the first z-axis data with the second z-axis data contained in or derivable from the confirmation signal.

A z-axis data updating system, comprising:

• a z-axis data source that is configured to obtain current z-axis data;
• a data storage system that is configured to store z-axis data;
• a signal generator that is configured to generate signals containing or encoded with z-axis data;
• a transceiver;
• and
• a computing system that is configured to:
• generate, using the signal generator, a first z-axis data signal containing first z-axis data corresponding to a location of the z-axis data updating system, based on current z-axis data obtained from at least one of the z-axis data source or the data storage system;
• and
• send, using the transceiver, a first z-axis data signal to a voice over Internet protocol (“VoIP”) telephone that is proximate to the z-axis data updating system, for transmission as a second z-axis data signal via the VoIP telephone over a VoIP connection over a network to a 911 or E911 address database system for decoding the second z-axis data signal to obtain the first z-axis data and for updating a first 911 or E911 address with the first z-axis data, the first 911 or E911 address being associated with a telephone number of the VoIP telephone.
