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
 Click Start > Control Panel > Network and
Internet Connections.
 Under See Also, click Phone and Modem
Options.
 In the Modems tab, select the installed modem,
and click Properties.
 In the Modem tab of the Modem Properties
window, clear the “Wait for dial tone before
dialing” check box.
 When the configuration is completed, click OK.
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.
 Click Start > Control Panel > Network and
Internet Connections.
 Under See Also, click Phone and Modem
Options.
 In the Dialing Rules tab, click Edit.
 In the General tab in the Edit Location window,
select the current country from the Country/
region radio box, specify the Area code, and
click OK.
A2 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.
