■ If the modem shares the telephone line with another device, make sure
that the telephone line is not in use (for example, someone is on the
telephone, or another modem is in use).
■ Use the modem cable that came with your notebook. Some telephone
cables do not meet required cable standards and may cause problems
with the modem connection.
■ Shut down and restart your notebook.
■ Run Windows modem diagnostics.

The modem is noisy when it dials and connects
When your modem tries to connect to another modem, it begins handshaking.
Handshaking is a digital “getting acquainted” conversation between the two
modems that establishes connection speeds and communication protocols.

the handshaking sounds are too loud, you can turn down the modem volume.

your Control Panel is in Category View, click Printers and Other
Hardware.
