in response to the current address associated with the mobile VoIP device being different from the registered address, substituting the current address for the registered address, sending the current address with the emergency call, and storing the current address associated with the mobile VoIP device; and

in response to the current address associated with the mobile VoIP device matching the registered address, sending the registered address with the emergency call.

14. The system of claim 13 , wherein sending the current address with the emergency call further comprises:

sending a Short Message Service (SMS) message containing the current address to a VoIP service switching center over an IP connection, the IP connection one of an 802.11 WiFi connection or a cellular IP data connection.

15. The system of claim 13 , wherein sending the current address with the emergency call further comprises:

sending a Message Queue Telemetry Transport (MQTT) message containing the current address to a VoIP service switching center over an IP connection, the IP connection one of an 802.11 WiFi connection or a cellular IP data connection.

16. The system of claim 12 , further comprising:

in response to the user response indicating acceptance of the presented current address, using the current address to place the emergency call, and storing the current address; and
