Root cause: nginx rewrite stripped file= param from {mac}.boot requests,
so FusionPBX served full device config as a .boot file. Yealink ignores
DSS/linekey settings in .boot files — they only apply from .cfg files.
Fixes applied on 134.209.72.226:
- nginx: {mac}.boot rewrite now passes file={mac}.boot param
- New {$mac}.boot template: proper boot file with includes to {mac}.cfg
- y000000000065.cfg: features.auto_linekeys.enable = 0
- All y000000000000.boot: overwrite_mode = 1
- External sofia profile: manage-presence = passive (was true)
- Park buttons: Speed Dial type=13 (*5901-*5903), not BLF (mod_presence missing)
