A telephone call on a remote line (190) is initiated by establishing simultaneous voice and data connection with a slave processor (180) tied to the remote line. The slave processor is responsive to commands received on the data connection, including an off hook command signaling the slave processor to go off-hook on both the voice connection and remote line. Thereafter, the slave processor (180) bridges the voice connection and remote line. Upon receipt of the digits of a telephone number entered on the voice connection, the slave processor, in turn will dial the digits on the remote line, thereby initiating a call on that line.
