QWhen you are unable to make a call when using a switchboard
AIn 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.
QWhen 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.
