56 LINGO TECHNICIAN’S GUIDE
Learning call progress tones
The tones used to identify the status of
a call vary from one telephone system to
another. These tones include dial tone,
busy tone, and ring back tone. Some tele-
phone systems also provide disconnect (or
reorder) tone and do-not-disturb tone. For
Lingo to correctly handle calls, it must
recognize how each of these tones sounds
with your telephone system. Lingo learns
these tones when you use the learn call
progress tones feature.
After system initialization, Lingo must learn
call progress tones for the site, before
handling calls.
To learn call progress tones
1 Confirm that the transfer and recall
sequences are indicated correctly in
the system options.
2 Analyze tone delays by using the Tone
Analysis Worksheet.
3 Adjust the tone delay system options
if indicated by the worksheet.
4 Conduct the tests to learn call
progress tones on Lingo.
Note To program your telephone system,
refer to the telephone system documenta-
tion. The Telephone System Guide provides
some programming information for many
telephone systems.
