|The Fax Jack allows your fax or modem to conveniently share your existing voice line.
Voice calls continue to ring to your phone, but automatic faxes will be sent directly to your fax machine. If someone sends a manual fax, the call can also be instantly transferred to the fax machine from your Touch Tone telephone.
If your office is unoccupied, all calls can be sent directly to your fax machine or they can be screened for voice messages by your answering machine.
If your phone company provides distinctive ringing, the Fax Jack will also automatically route all fax calls to the fax machine and voice calls to the telephone.
