Q
When you are unable to make a call when using a
switchboard
A
In general, the dial tone of a switchboard or a digital
phone switching system is not continuous unlike that
of a PSTN line. Therefore, the modem may not make
a phone call as it misreads the dial tone as a busy
tone. In this case, perform the following.
Use the AT Command
Add the ATX3 command for initialization.
Alternatively, enter the ATX3 command first before
make a phone call.
The modem will not check the dial tone before
making a phone call.
Configuring the Model in the Control Panel
Click
Start > Control Panel > Hardware and
Sound
.
Click on
Phone and Modem Options
.
In the
Modem
tab, select an installed modem
and click
Properties
.
In the
Modem
tab of the Modem Properties
window, unselect the
Make a phone call after
waiting for a dial tone
option.
When the settings are complete, click the
OK
button.
If you cannot make a phone call starting with
a 0, such as 01432, 01421, 01433, etc., this is
because the private switching system is set to block
long distance calls. Ask your switching system
administrator.
Q
When using the modem overseas
A1
Check if the country setting of the modem is set to
the current country.
Since each country has slightly different
telecommunication values, if the location is not set
to the corresponding country, the modem may fail to
make a phone call.
Click
Start > Control Panel > Hardware and
Sound
.
Click on
Phone and Modem Options
.
In the
Dialing Rules
tab, click
Edit
.
In the
General
tab of the Edit Location window,
set the Country/Region to your current country,
enter the region code and then click the
OK
button.
A2
Since the shape of the phone line connector may
differ depending on the country you are in, you may
have to buy a phone line connector to make a phone
call from that country.
