Pin existing CloudFormation stack name via stackName property so
the live stack is not affected. Construct ID and API Gateway name
now follow the org kebab-case standard.
Add phone_setting.blf_list_enable = 1 which was present in the T54W
template but missing from the stock T5x base. Without it, BLF and
shared parking keys show X's instead of green/red status.
Change y000000000150.cfg → y100000000150.cfg across all three references
(deviceconfig filename, model filename, auto_provision.common_file_name)
to avoid conflicting with the stock 3CX template, consistent with the
T54W templates. Also update the second data section friendly name.
Based on the official 3CX T5x template, stripped to T58W-only with the
door unlock URL hardcoded on line key 2 (type 17/URL). Keys 3+ remain
managed by 3CX BLF as usual.
- Backlight dims to level 1 after 5 min, never fully sleeps
- Screensaver and power saving disabled
- README updated with T54W references and SP template manual steps
Two variants:
- yealinkT54W-door-unlock.ph.xml — line key 2 as door unlock URL
- yealinkT54W-door-unlock-with-sp.ph.xml — line key 2 as door unlock, keys 3-5 as shared parking SP1-3
