If you are experiencing “Failed, Line unavailable” errors, or if the DVR is not connecting
to the DVR service, you may have a low-voltage phone system that the DVR cannot
detect. In this case, it’s best to have ‘Phone Avail.’ Detection off.
Set Dial Tone Detection.
This setting is on by default. If you leave it on, the DVR will
check for a dial tone before it starts dialing. However, if you have a non-standard dial
tone, or a stuttering dial tone (as some voice messaging systems have), the DVR will be
unable to detect the dial tone and will not make its call.
Restore previous options.
The DVR must make a successful test phone call before it will
accept changes to Phone Dialing Options. If you want to restore your previous dialing
options and continue past this screen without making a test phone call, select “Restore
previous options.”
With Dial Tone Detection and
‘Phone Avail.’ Detection both
turned off, if you happen to be talking on
the phone when the DVR tries to call you
will hear the modem dial and try to
communicate with the DVR service.
