Abstract
The invention provides a method of transitioning between voice and data communications with a mobile vehicle. A switch-to-voice command signal is sent from a call center modem pool to the mobile vehicle, and a vehicle switch-to-voice acknowledgement signal is received at the call center. A call from the call center modem pool is switched to a call center advisor in response to the vehicle switch-to-voice acknowledgement signal.
