Hi support@thearcehouse.com,

If you want set blf of line1, the code should be like that.

Code:

linekey.1.line = 1
linekey.1.value = 121
linekey.1.pickup_value =
linekey.1.type = 16
linekey.1.label = Sergio
linekey.1.extension =

Note: if you want to pickup the monitored number(121), you should add the
linekey.1.pickup_value = "the pickup code". Gennerally, it is *20* in the 3CX PBX. If not, you should ask your network administrator or PBX server provider for help.
Best regards
