Transfer of unidentified incoming calls
(Express Modem only)
Your modem identifies the type of incoming call by
detecting the calling tones sent by modems and fax
machines. Since not all devices use calling tones, some calls
cannot be identified. To enable the modem to answer
unidentified calls—when calling tone detection is
unsuccessful—use the “Transfer incoming calls” buttons to
choose the program to answer unidentified calls.
If you are going to receive voice calls, choose “Voice.” If you
are going to receive data calls, choose “Data.” If you expect
to receive both voice and data calls, ask your callers to send a
data calling tone when calling your machine.
Make sure you set the program designated to handle
unidentified calls (voice, fax, or data) to auto-answer.
Note: Transfer of unidentified calls is performed
automatically in the Apple Serial Modem software, but for fax
and voice calls only.
Ignore dial tone when dialing
When the “Ignore dial tone when dialing” checkbox (known
as blind dialing) is selected, the modem dials even though a
dial tone cannot be detected. This is a useful feature for
locations with a PBX system, such as hotels, where the
modem may have difficulty recognizing the PBX dial tone.
Selecting the checkbox has the same effect as setting the AT
command ATX3 for all programs.
Leaving “Ignore dial tone when dialing” deselected allows
you to control blind dialing at the program level.
