Parameter
account.X.blf_list_call_parked_list
[1]
<MAC>.cfg
Description
It configures the serial numbers of the monitored users in the BLF list where you can park the active
call for account X.
Multiple serial numbers are separated by commas.
Example:
account.1.blf_list_call_parked_list =
When you leave it blank, you cannot park the active call to any monitored user.
account.1.blf_list_call_parked_list = all
You can park the active call to any monitored user.
account.1.blf_list_call_parked_list = 1,3,4
You can park the active call to the first, third or fourth monitored user in the BLF list.
Note: This parameter has a higher priority than “transfer.dsskey_deal_type”, so that when you press
the BLF list key during a call, the phone parks a call other than transferring the call. It works only if
“account.X.blf_list_call_parked_code” is configured.
