The Uniform Resource Identifier (URI) of the Busy Lamp Field (BLF) list that you have set up for a user of the phone, on the BroadWorks server.

This field is only applicable if the phone is registered to a BroadWorks server. The BLF list is the list of users whose lines the phone is allowed to monitor.

The BLF List URI must be specified in the format <URI_name>@<server>. The BLF List URI specified must be the same as the value configured for the List URI: sip parameter on the BroadWorks server.

Perform one of the following:

• In the phone configuration file with XML(cfg.xml), enter a string in this format:

  <BLF_List_URI ua="na">MonitoredUsersList@sipurash22.com</BLF_List_URI>

• On the phone web interface, specify the BLF list that is defined on the BroadSoft server.

Default: Blank

Controls whether the phone uses its line keys to monitor the BLF list, when monitoring of the BLF list is active.

This setting only has significance when BLF List is set to Show.

Perform one of the following:

• In the phone configuration file with XML(cfg.xml), enter a string in this format:

  <Use_Line_Keys_For_BLF_List ua="na">Yes</Use_Line_Keys_For_BLF_List>

• On the phone web interface, set this field to Yes to use the unregistered lines to monitor the BLF list entries. Set it to No to prevent the line keys from being used for monitoring the BLF list entries.

Default: No

Determines whether to show or hide the BLF list on the line key.

When set to Show, the phone assigns available line keys in sequence, to monitor the BLF list entries. The labels of the BLF list keys show the names of the monitored users and the status of the monitored lines.

This setting only has significance when BLF List URI is configured.

Perform one of the following:

• In the phone configuration file with XML(cfg.xml), enter a string in this format:

  <BLF_List ua="rw">Show</BLF_List>

• On the phone web interface, set this field to Show or Hide to activate or deactivate the BLF monitoring feature.

Allowed values: Show|Hide

Default: Show

BLF Label Display Mode

Specifies how the BLF entries are displayed on the line keys. The options are: Name, Ext (extension number), and Both.

Perform one of the following:

• In the phone configuration file with XML(cfg.xml), enter a string in this format:

  <BLF_Label_Display_Mode ua="na">Name</BLF_Label_Display_Mode>

• On the phone web interface, select an option from the list.

Allowed values: Name|Ext|Both

Default: Name

Extension

Assigns an extension number to a line key or disables the extension function on a line key.

The number of line keys varies with phone models. When assigned with an extension number, you can configure the line key as a telephony extension.

When you need to assign the line key with extended functions (for example, speed dial, BLF, call pickup) while the Direct PLK Configuration feature is disabled, you can either enable the feature or set the Extension parameter to Disabled.

Perform one of the following:

• In the phone configuration file with XML(cfg.xml), enter a string in this format:

  <Extension_1_ ua="na">1</Extension_1_>

  <Extension_2_ ua="na">2</Extension_2_>

  <Extension_3_ ua="na">3</Extension_3_>

  <Extension_4_ ua="na">4</Extension_4_>

• On the phone web interface, set the parameter to Disabled to monitor another line on the line key.

Allowed values: Disabled|1|2|3|4, the allowed values vary with phones.

Default: n, where n is the line key number.

Extended Function

This parameter functions only on the lines with the Extension parameter set to Disabled.

Used to assign extended functions to a line on the phone. The supported functions are:

• BLF with Call Pickup

  Example: fnc=blf+cp;sub=BLF_List_URI@$PROXY;ext=user_ID@$PROXY

• BLF with Speed Dial

  Example: fnc=blf+sd;sub=BLF_List_URI@$PROXY;ext=user_ID@$PROXY

• BLF with Speed Dial and Call Pickup

  Example: fnc=blf+sd+cp;sub=BLF_List_URI@$PROXY;ext=user_ID@$PROXY

Where, user_ID represents the ID of the monitored phone.

Perform one of the following:

• In the phone configuration file with XML(cfg.xml), enter a string in this format:

  <Extended_Function_1_>fnc=blf;sub=BLF_List_URI@$PROXY;ext=user_ID@$PROXY</Extended_Function_1_>

• In the phone web interface, configure the parameter with a valid syntax to enable monitoring another user or extension using the line.

Default: Empty
