An autodialer including a DTMF transceiver for connection between a user telephone device and the telephone line. The DTMF transceiver is connected in a double isolation mode to allow for monitoring of DTMF tones from either the telephone line or from the user telephone device. The DTMF transceiver is connected to a microprocessor for processing a plurality of program instructions stored in a memory device. The autodialer uses its program instructions to determine how to handle outgoing dial sequences. At the start of an outgoing call, the digit sequences and outgoing dial sequences. At the start of an outgoing call, the autodialer monitors the DTMF tones generated by the user telephone device looking for an intercept digit sequence. If an intercept digit sequence occurs, the autodialer hangs up on the telephone line and begins an outgoing dial sequence while continuing to capture the additional DTMF tones from the user telephone device. When the autodialer completes the outgoing sequence, it performs a cut-through to connect the user telephone device to the telephone line.
