Abstract
A system and method for placing an emergency call using a initiating device. A initiating device receives a request to place an emergency call. Upon determining that a VoIP-based emergency call cannot be placed, the initiating device identifies a proximate proxy device. The initiating device directs the proxy device to place the emergency call.
Claims20
An initiating device capable of placing VoIP calls comprising:
- a processor;
- a memory device containing machine-readable instructions that control the device to:
- detect a request for emergency services;
- determine whether the initiating device is or is not confirmably present at a registered location;
- upon determining the initiating device is not confirmably present at the registered location, confirm a proximity within a range of a proxy device to the initiating device;
- and
- upon confirming the proximity within a range of the proxy device, route the request for emergency services through the proxy device.
A storage device containing instructions that direct an initiating device capable of placing VoIP calls to:
- detect a request for emergency services;
- determine whether the initiating device is or is not confirmably present at a registered location;
- upon determining the initiating device is not confirmably present at the registered location, confirming a proximity within a range of a proxy device to the initiating device;
- and
- upon confirming the proximity within a range of the proxy device, route the request for emergency services through the proxy device.
A method of placing an emergency call from an initiating device capable of placing VoIP calls, the method comprising:
- detecting, by the initiating device, a request for emergency services;
- determining, by the initiating device, whether the initiating device is or is not confirmably present at a registered location;
- upon determining the initiating device is not confirmably present at the registered location, confirming, by the initiating device, a proximity within a range of a proxy device to the initiating device;
- and
- upon confirming the proximity within a range of the proxy device, routing, by the initiating device, the request for emergency services through the proxy device.
