Abstract
A method for recognizing an attempted data connection in a wireless network between a telematics unit and a call center using a modem. During the connection attempt, a determination is made whether frequencies received through the modem are audio frequencies or data frequencies. The connection is abandoned prior to a time-out if frequencies received through the modem are audio frequencies.
