A mobile wireless terminal is provided. The mobile wireless terminal includes a wireless unit, an audio codec, and a processor unit. The wireless unit is configured to connect to a wireless relay to make a voice communication with a phone network via the wireless relay, which is coupled between the mobile wireless terminal and the phone network. The audio codec is configured to process the voice communication. Further, the processor unit is coupled to the wireless unit and is configured to obtain a phone number from a user for an outgoing call to an external party in the phone network, and to connect to the wireless relay over a short-range wireless link. When the connection to the wireless relay is successful, the processor unit is configured to establish a signaling connection on an asynchronous connection-oriented logical (ACL) transport channel, and a voice connection on a synchronous connection oriented (SCO) channel between the mobile wireless terminal and the wireless relay. Further, the processor unit is configured to send the dialed outgoing call to the wireless relay via the signaling connection, and to communicate with the external party via the wireless relay over the voice connection.
