Cheat code
Emergency cheat sheet
- Direct 911. A required prefix fails Kari's Law in the United States.
- On-site notification is a second duty.
- Callback must reach the site that dialed, not a headquarters receptionist.
- Webex and Teams locations are not a CUCM ELIN. Name the product before you test.
Source: FCC MLTS 911 requirements. Other countries have their own rules.
