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.

make a phone call.
The modem will not check the dial tone before
making a phone call.

because the private switching system is set to block
long distance calls. Ask your switching system
