Auto Line Labels Rule Configuration
When assigning multiple line keys per account, these automatically assigned line keys use its Account Label (set
by “account.X.label”) as default label to display on the screen. In order to distinguish these automatically assigned
line keys, you can customize the line key labels one by one or configure the auto line labels rule for these line keys.
The following table lists the parameters you can use to configure the auto line labels rule.
Parameter
account.X.auto_label.enable
[1]
<MAC>.cfg
Description
It enables or disables the Auto Label feature. It is only applicable to the automatically assigned line
DSS keys.
Note: It works only if “features.auto_linekeys.enable” is set to 1 (Enabled).
Permitted
Values
0-Disabled, the line keys labels are determined by “account.X.label”.
1-Enabled, the line keys labels are determined by the custom label rule (configure by the parameter
“accout.X.auto_label.rule”).
Default
0
Supported
Devices
All phones except T19(P) E2 and CP920
Parameter
account.X.auto_label.rule
[1]
<MAC>.cfg
Description
It configures the Auto Label rule.
You need to know the following basic regular expression syntax:
{L}: The value is configured by the parameter “account.X.label”.
{N}: An increasing number from N. For example, abc{1}{5} represents the following labels: abc15,
abc26, abc37, and so on.
Multiple labels are separated by “|”. For example, Yea|Yea|Yea|Tom_{2} means to display “Yea” for
first three line keys, and from the fourth one, display label Tom_2, Tom_3, and so on in turn.
Other Characters: for example, ABC, will display ABC the same as what you have configured.
Note: It works only if “features.auto_linekeys.enable” and “account.X.auto_label.enable” are set to 1
(Enabled). The number of valid labels is configured by the parameter “account.X.number_of_linekey”.
