win-
dow to diagnose the modem.
No message in either of Command and Response in the

Diagnose the modem again after restarting the system or reinstalling the driver.

Q2 I cannot make a call using an extension line.
A In general, the dial tone of a PABX 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 PABX 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
