Abstract
A system and method of communicating data between a vehicle and call center via a voice channel of a wireless communication system. The method carried out by the system includes the steps of: establishing a voice channel connection between a vehicle telematics unit and call center via a wireless cellular network; generating a modem signaling carrier comprising a prefix followed by a single frequency tone; sending the modem signaling carrier over the voice channel connection using an EVRC-B vocoder; establishing a data communication session over the voice channel connection in response to the modem signaling carrier; and thereafter carrying out data communications between the vehicle telematics unit and call center during the data communication session.
