Zoom V.34 Plus Quick Start Manual page 19

Problem: The faxmodem does not automatically dial a call
when you use your software to dial a number.
Solution: Make sure the modem speaker is turned on and the
volume setting is turned up in your software so that you
can hear dialing sounds. Also make sure that the phone
line is plugged in. If you are using tone dialing on a line
that requires pulse dialing, the line may not be able to
accept tone-dialed calls. Select pulse dialing in your
software.
