ABSTRACT:
A control circuit for a telephone answering device provides the capability of disconnecting the telephone answering device from a telephone line and powering a microphone contained within a telephone handset connected to the telephone answering device. Recording of outgoing messages can then be done through the telephone set thus reducing background and tape noise. The control circuit also provides the capability of disabling the functions of the telephone answering device when any telephone set, connected to the same telephone line as the telephone answering device, is taken off-hook.
