Abstract:
1. A method of obtaining vehicle data during a multi-way call involving a vehicle telematics unit, call center, and at least one third party, comprising the steps of: conducting a multi-way voice call involving at least three different phone terminal units which include a vehicle telematics unit, a call center terminal, and a third party terminal, wherein the multi-way voice call involves a telephone connection to the telematics unit and a telephone connection to the third party terminal; separating the multi-way voice call into a two-way call and a second multi-way call, wherein the two-way call is switched from a voice transmission mode to a data transition mode when vehicle data is sent between the call center and the vehicle telematics unit while maintaining voice communications between the call center and the third party; receiving, at a data receiver, vehicle data sent from the telematics unit over the two-way call; and ending the two-way call with the data receiver and reconnecting the telematics unit to the multi-way voice call without ending the telephone connection to the telematics unit.
