ABSTRACT:
A vehicle user can request emergency or roadside assistance from a response center by activating a button in the vehicle. The global positioning system is used to continuously store the vehicle location. A cellular telephone network is used to contact a response center and transfer a data string via modem containing information to assist the response center in acting on the request. If a first attempt to contact the response center at a phone number for receiving a data transfer is unsuccessful, a second call is made to a different number bypassing the data transfer and immediately placing the cellular phone into an unmuted condition. This allows the user to hear and interact with a cellular operator, if necessary, prior to being connected to the response center.
