A mobile communication device (100) uses a local wireless transceiver (108) to establish an asynchronous link (202) with a remote audio processor (110) which is typically operated in a low power mode and that maintains an association between the mobile communication device and remote audio processor. When the mobile communication device receives an incoming call page (210), the mobile communication device initiates a synchronous link with the remote audio processor, and responds to the incoming call page at a time when the call will be connected only after the synchronous link is established.
