Abstract
A method and apparatus for allowing a transparent service option transition between at least two wireless communication devices (WCDs). A first communication between a first WCD and a second WCD is established using a first service option. At some point during the first communication, a transition to a second service option, such as an asynchronous data service option, is initiated. At least one of the WCDs provides an identification code to the other WCD using a signaling protocol over the first service option. The first communication is then terminated. A second communication using the second service option is then initiated by one of the WCDs, resulting in a seamless transition to the second service option.
