How do I set up a answering machine (TAD) to work on the same line as the fax?

When you have an external telephone answering device (TAD) on the same telephone line as the fax machine, the TAD answers all calls and the fax machine "listens" for fax calling (CNG) tones. If it hears them, the fax machine takes over the call and receives the fax. If it doesn't hear CNG tones, the fax machine lets the TAD continue playing your outgoing message so your caller can leave you a voice message.


The TAD must answer within four rings (the recommended setting is two rings). The fax machine cannot hear CNG tones until the TAD has answered the call, and with four rings there are only 8 to 10 seconds of CNG tones left for the fax "handshake". Make sure you carefully follow the instructions below for recording your outgoing message. We do not recommend using the toll saver feature on your external answering machine if it exceeds four rings.

If you do not receive all your faxes, you must reset the setting on your external TAD to four rings or less.

  • Limit your speaking to 20 seconds.


  1. Set the TAD to answer calls.
  2. Set the Receive Mode to
