ABSTRACT:
A method and system for setting up an emergency services call (ESC) to an emergency services network (ESN), where the method involves receiving a request to set up an ESC between a calling device and an ESN, determining whether the calling device is a fixed device or a mobile device, setting up the ESC to a wireless telephone number of the ESN if the calling device is a fixed device, and setting up the ESC to a wireless telephone number of the ESN if the calling device is a mobile device. In the case of the calling device being a fixed device, an ESC conversation is sent to the wireless telephone number of the ESN via a wireless air interface, and location determination information for determining the location of the calling device is sent to a landline signaling interface of the ESN using out-of-band signaling.
