A multi-line modem interface circuit includes a processor and a sensing circuit coupled to the processor. The sensing circuit is operable to identify a status of one or more external lines and communicate the status to the processor. A control circuit is coupled to the processor, and the processor is operable to automatically configure a line connection configuration for either incoming or outgoing voice or data communications in accordance with programmed, user-defined preferences associated with the processor. The interface circuit is operable to automatically monitor a line to determine if it's ringing, determine whether it's allowed and couple the line to the modem for potential answer. The interface circuit line monitoring is non-invasive and keeps the modem from interfering with calls in progress. A method of interfacing multiple external phone lines with one or more internal lines and a modem for incoming or outgoing voice or data transmissions includes the step of monitoring a modem to determine whether the modem is attempting to initiate a transmission via an external line. In addition, the method includes determining whether the external lines are available or allowed for the outgoing transmission and coupling an external line to the modem in response to the determination.
