I am using Voice Over Internet Protocol (VoIP) and cannot send and/or receive faxes. What can I do?

Voice Over Internet Protocol (VoIP) is not a marketed feature of your Brother machine; however there is a "Compatibility" setting available with this machine that may assist with sending and receiving faxes when using VoIP (Voice Over Internet Protocol). Adjusting this setting lowers the baud rate (modem speed) and turns ECM (Error Correction Mode) Off. To adjust the "Compatibility" setting follow the steps listed below:


  1. Press Menu or Menu/Set key, Fax, Miscellaneous, and Compatibility.
  2. Press the up or down arrow key to select Basic.
    Basic reduces the modem speed to 9600 bps.
  3. Press OK or Menu/Set or Set key.
  4. Press Stop/Exit.

    Although VoIP is not a marketed feature of this machine, Brother will continue to monitor customer requests for possible future products.
