* Add lockdown profile toggle endpoints with T58W linekey support
Add a new Lambda handler that toggles Elements lockdown profiles
(Bohemia and Ronkonkoma) via the Elements API, with status
verification before and after each toggle. Returns Yealink XML
to control linekey LEDs (green=inactive, red=locked down).
Also brings both Lambda handlers into compliance with system
standards: Node 22.x runtime, arm64 architecture, 60-day log
retention, and kebab-case function names.
* Add lockdown poller Lambda and fix lockdown handler responses
- Add VPC-connected poller Lambda that monitors lockdown status via
Elements API every 15 seconds (4 polls per 1-min EventBridge schedule)
- Handle Elements API rate limits (429) with retry-after support
- Fix lockdown handler to use TextScreen XML instead of Execute XML
(Execute shows globe icon on T58W, TextScreen renders properly)
- Fix Elements API status parsing to be case-insensitive
- Trust toggle action instead of re-checking status (eventual consistency)
- Configure push_xml.server = any in T58W template for Push XML support
- Clear action_url.setup_completed (poller replaces boot-time check)
- Update README with lockdown architecture and known LED limitation
Note: T58W line key LED color does not change to reflect lockdown
status. Execute LED commands are transient on the T58W - the phone's
XML Browser key type immediately overrides them.
* Add buildspec for CodePipeline CI/CD
* Update README with CI/CD pipeline details
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
