Know at 2am, not at 8am
Voice is still the thing customers notice first when it dies. Partner shops without a 24×7 NOC need alerts that are boring and reliable — not another end-user status page.
The situation
A site loses registration or the PBX stops answering. The first ticket is “phones are down” from the receptionist.
What Kestrel does
- Polls status on an interval and records the last good time.
- Raises PBX-down and stale-data events when a box disappears or stops updating.
- Partner defaults, or a per-host page when one box should differ.
- Email the on-call or a shared ops inbox. Saving can write the same types to the 3CX console.
