AUTO LINC UP
3. After the dial tone expires, you should hear one
of the following:
a. Recorded Operator message—this message will
usually be “If you’d like to make a call, please hang
up and try again...”
b. Error Tone—the error tone may sound like a fast
busy signal, an alternating high–low tone, or dead
silence.
If the result of the DTT is the recorded operator
message, there is a 95% probability that the phone
system will support autodialing with the Linc Up. If
the result of the DTT is an error tone, there is a 95%
probability that the phone system will not support
autodialing with the Linc Up.
Approximately 65% of the phone systems that require
the dialing of a prefix such as a “9” or some other
number to dial out of the building will require the
prefix to be dialed manually (using the keypad of the
phone) before having the modem/fax dialing the rest
of the number.
