Description:
Configures the page switch key LED status on the expansion module when BLF monitored
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: illuminates solid red for 300ms and
then goes out for 300ms.
Note: It works only if the value of the parameter
“expansion_module.page_tip.blf_call_in.enable” is set to 1 (Enabled). It is only applicable to
EXP50 expansion modules connected to the SIP-T54S/T52S IP phones.
