ABSTRACT:
Telephone calls from an extension (32) on a private branch exchange (PBX) (14) are directed by an automatic telephone dialer (12a) to an outside line (18) of a local operating company or to a dedicated line (22) connected to the facilities of a specialized common carrier. The dialer is connected to an extension line (36) simply as another extension. A call from an extension (32) requesting an outside line is directed to the extension occupied by the dialer (12a), and a ring detector (40) detects the resultant ringing signal and alerts a controller (44). The controller sends a dial tone to the calling extension (32) and records the resultant dialed digits. It then momentarily interrupts its off-hook signal to cause the PBX to place the calling station (32) on hold and dials the appropriate destination. Once the dial has been replaced, it "hangs up," causing the PBX to connect the calling extension (32) to the destination that the automatic dialer has called.
