Q
I cannot make a call using an extension line.
A
In general, the dial tone of a PBX or a digital
phone switching system is not a continuous
one, unlike that of a trunk line.
Therefore, the modem may not make a call because
the modem mistakes the dial tone from a PBX or a
digital phone switching system as a busy tone. In this
case, complete the following procedures.
▶
Using an AT command
As an initialization command, use the command,
ATX3. Otherwise, enter the ATX3 command
manually before making a call.
It can correct this problem by skipping the dial tone
check step.
▶
Configuring the Modem through the Control
Panel

Internet Connections

Q
How do I use my modem when dialing from
overseas?
A1
Check that the modem is correctly
configured according to the current country.
Because the values for communication may differ
according to the country, you may not be able to
connect via the modem due to an incorrect modem
configuration.

Internet Connections

Because the shape of the telephone plug
may differ according to the country, you
have to purchase and use the appropriate
telephone plug for that particular country.
