Telephone Line Interference/VoIP.
If you are having issues sending or receiving a fax due to possible interference on the telephone line or if you are using a VoIP system, we recommend changing the modem speed to minimise errors in fax operations.
-
Press (Settings) > All Settings > Initial Setup > Compatibility.
-
Press the option you want.
-
Basic(for VoIP) reduces the modem speed to 9,600 bps and turns off color fax receiving(*) and Error Correction Mode (ECM), except for color fax-sending(*). Unless interference is a recurring issue on your telephone line, you may prefer use it only when needed.
To improve compatibility with most VoIP services, Brother recommends changing the compatibility setting to Basic(for VoIP).
