Telephone and external devices

If you have questions about how to
connect your machine to the VoIP
system, contact your VoIP provider.
After you have connected your machine to
the VoIP system, check for a dial tone. Lift the
external telephone's handset and listen for a
dial tone. If there is no dial tone, call your
VoIP provider.
If you are having problems sending or
receiving faxes over a VoIP system, we
recommend changing the machine’s modem
speed to the Basic(for VoIP) setting
(see Telephone line interference / VoIP
on page 91).
• VoIP (Voice over IP) is a type of phone
system that uses an Internet connection,
rather than a traditional phone line.
• Brother does not recommend the use of a
VoIP line. VoIP limitations in general can
cause some functions of the fax machine
not to work correctly.
Connecting an external
TAD (telephone
answering device)
7
You may choose to connect an external
answering device. However, when you have
an external TAD on the same telephone line
as the machine, the TAD answers all calls
and the machine “listens” for fax-calling
(CNG) tones. If it hears them, the machine
takes over the call and receives the fax. If it
does not hear CNG tones, the machine lets
the TAD continue playing your outgoing
message so your caller can leave a voice
message.
The TAD must answer within two rings (the
recommended setting is two rings). The
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 in this
guide for recording your outgoing message.
We do not recommend using the toll saver
feature on your external answering machine if
it exceeds five rings.
If you do not receive all your faxes,
shorten the Ring Delay setting on your
external TAD.
