Abstract
A telecommunication system and method that allow a data exchange to be initiated while a user is engaged in a voice communication using a non-class A endpoint (e.g., cellular telephone, personal digital assistant, etc.) with another party. One example method maintains a first voice communication leg to the wireless device and a second voice communication leg to the second device, inputs a request for the data exchange during the voice communication, disconnects the first voice communication leg, parks the second voice communication leg and waits for data to be transmitted to or from the wireless device. Once it is determined that the data exchange is complete, the method establishes a third voice communication leg to the wireless device, unparks the second voice communication leg and connects the second and third voice communication legs.
