Confirming transfer and recall
sequences
Different telephone systems vary in the
sequences that must be dialed to transfer
a caller and to return to a caller if an exten-
sion does not answer an attempted transfer.
For Lingo to learn tones correctly, it must
know the correct dialing sequences for
these two functions.
To confirm the transfer and recall sequences
1
Determine the transfer and recall
sequences for your telephone system.
Your telephone system documentation
provides this information.
2
Using three single-line telephones,
verify that these sequences work cor-
rectly by simulating a transfer and a
recall.
3
Access the technician’s conversation.
4
Select action 5 to change system
options.
5
Press 370 to confirm or change the
transfer sequence.
6
Press 372 to confirm or change the recall
sequence.
Analyzing tone delays
Different telephone systems vary in the
length of time elapsed before providing
a tone, as well as the duration of the tone
itself. To ensure that Lingo learns the cor-
rect tone and that it has enough time to
learn it completely, you must first simulate
each tone and then answer the questions in
the Tone Analysis Worksheet.
Complete the worksheet before initiating
the call progress tone tests on Lingo.
To complete the worksheet, you need:
• Two analog extensions from the tele-
phone system
• Two single-line sets with no forwarding,
second-line ringing, or camp-on
enabled
• A clock or watch that can measure
seconds
