Samsung NP-X22A009/SEF 158, QI cannot make a call using an extension line, Using an AT command

QI cannot make a call using an extension line.

AIn 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.

QHow 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.
