Set Telephone Line Compatibility for Interference and VoIP Systems

Related Models: MFC-B7715DW
Problems sending and receiving faxes due to possible interference on the telephone line may be solved by
reducing the modem speed to minimise errors in fax transmission. If you are using a Voice over IP (VoIP)
service, Brother recommends changing the compatibility to Basic (for VoIP).
VoIP is a type of phone system that uses an Internet connection, rather than a traditional phone line.
Telephone providers frequently bundle VoIP together with Internet and cable services.
1. Press Menu.
2. Press a or b to display the [Initial Setup] option, and then press OK.
3. Press a or b to display the [Compatibility] option, and then press OK.
4. Press a or b to display the [High], [Normal], or [Basic(for VoIP)] option, and then press OK.

Select High to set the modem speed at 33600 bps.
Select Normal to set the modem speed at 14400 bps.
Select Basic(for VoIP) to reduce the modem speed to 9600 bps and turn off Error
Correction Mode (ECM). Unless interference is a recurring problem on your telephone
line, you may prefer to use it only when needed.
To improve compatibility with most VoIP services, Brother recommends changing the
