Expansion Module Page Tips Configuration
The following table lists the parameters you can use to configure expansion module page tips.
Parameter
expansion_module.page_tip.blf_call_in.enable <y0000000000xx>.cfg
Description
It enables or disables the page switch key LED on the EXP50/EXP43 expansion module to indicate
when BLF monitored user receives an incoming call on the non-current pages.
Permitted
Values
0-Disabled
1-Enabled
Default
1
Supported
Devices
T57W, T54W, T53W, T53, T48U, T46U, T43U
Parameter
expansion_module.page_tip.blf_call_in.led <y0000000000xx>.cfg
Description
It configures the page switch key LED status on the EXP50/EXP43 expansion module when BLF mon-
itored user receives an incoming call on the non-current pages.
This value uses the same macro action string syntax as an Enhanced DSS key.
If it is left blank, the default value takes effect.
Example:
expansion_module.page_tip.blf_call_in.led = $LEDr300o300$
It means an infinite loop for page switch key LED status: glow red for 300ms and then be in the off
state for 300ms.
Note: It works only if “expansion_module.page_tip.blf_call_in.enable” is set to 1 (Enabled).

Default
$LEDr300o300$

Time and Date
Yealink phones maintain a local clock. You can choose to get the time and date from SNTP (Simple Network Time
Protocol) time server to have the most accurate time and set DST (Daylight Saving Time) to make better use of day-
light and to conserve energy, or you can set the time and date manually. The time and date can be displayed in sev-
eral formats on the idle screen.
