60 4600 Series IP Telephone Installation Guide
where setting corresponds the current Alert value (NVALERT):
● Setting is audible-only when NVALERT = 0
● Setting is audible/visual when NVALERT = 1
As of software Release 2.8, the system value AUDASYS can be set to allow or prevent the
user from changing the type of alerting (audio or visual), as specified in Chapter 4 of the
4600 Series IP Telephone LAN Administrator Guide:
● When AUDASYS is set to 0, the user is allowed visual alerting only (audible alerting is
not allowed, regardless of the value NVALERT).
● When AUDASYS is set to 1, the user is allowed audible alerting only (visual alerting is
not allowed, regardless of the value of NVALERT). When visual alerting is not allowed
(AUDASYS is set to 1), the user is not allowed to reduce the audio alerter below the
minimum loudness level.
● When AUDASYS is set to 2, the user is allowed visual alerting, and is also allowed to
change to audible alerting (regardless of the value of NVALERT).
● When AUDASYS is set to 3, the user is allowed audible alerting, and is also allowed to
change to visual alerting (regardless of the value of NVALERT).
● When AUDASYS is not set in the settings file, the default value of 3 is used unless
NVALERT is set to 0.
Because it does not have a display, the 4601 IP Telephone’s Call Appearance Line a’s
indicator winks out the current NVALERT value 600 milliseconds on, 200 milliseconds off,
where one wink represents “0” for audible only and two winks represent “1” for audible/
visual. If the current value is zero (the default), Call Appearance Line a’s indicator flutters
five times 50 milliseconds on, 50 milliseconds off instead of winking. After the 4601
“displays” the current NVALERT value, the Message Waiting indicator at the top of the
telephone and the Message button LED on the faceplate flash 500 milliseconds on, 500
milliseconds off to indicate an entry is expected.
2. To change the Alerting value, press *.
Depending on the current value, the other value is selected and displayed. For example, if
the current value is audible/visual (1), pressing * changes the value to 0 (audible only, the
default). If the current value is audible-only (0), pressing * changes the value to 1 (audible/
visual).
All IP telephones except the 4601 display the following text left-justified at the top of the
display:
The 4601 IP Telephone instead flashes both Message Waiting indicators 500 milliseconds
on, 500 milliseconds off to indicate an entry is expected.
