A telecommunication system (10a) and method (100) that allow a data exchange (100h) to be initiated while a user is engaged in a voice communication (100a) using a non-class A endpoint (e.g., cellular telephone, personal digital assistant, etc.) with another party. One example method (100) maintains a first voice communication leg (100a) to the wireless device and a second voice communication leg (100b) to the second device, inputs a request for the data exchange during the voice communication (100c), disconnects the first voice communication leg (100f), parks the second voice communication leg (100g) and waits for data to be transmitted to or from the wireless device (100h). Once it is determined that the data exchange is complete (100i), the method establishes a third voice communication leg to the wireless device (100j), unparks the second voice communication leg and connects the second and third voice communication legs (100k, 100l).
