Glossary
- E911
- Enhanced 911: emergency calling with callback and location information delivered through the emergency workflow.
- 911 answering center
- Public Safety Answering Point: the call center that answers 911 calls for a jurisdiction.
- Dispatchable location
- A validated street address plus usable detail such as floor, suite, room, wing, zone, or entrance.
- 911 location database
- Automatic Location Information: location data associated with emergency call handling.
- caller-number information
- Automatic Number Identification: caller/callback identifier used by emergency systems.
- PIDF-LO
- Presence Information Data Format - Location Object, often used to carry location in IP-based call flows.
- HELD
- HTTP-Enabled Location Delivery, used by some systems to retrieve endpoint location.
- business phone system
- Multi-line telephone system: enterprise or campus phone systems with multiple users/extensions.
E911 rollout checklist
- Confirm direct 911 dialing without outside-line prefixes.
- Verify internal notification recipients and message content.
- Validate every civic address with the provider or platform.
- Add dispatchable detail for large, multi-floor, or multi-building locations.
- Test callback numbers for shared phones, softphones, and common areas.
- Retest after SIP voice trunk, session border controller, network, facility, or UC policy changes.
- Keep exception owners and retest dates visible.
Provider RFP questions
- Describe address validation method and failure reporting.
- Show how fixed, nomadic, and remote users are handled.
- Provide test-call process and evidence format.
- Document outage and 911 answering center-impact notification procedures.
- Explain emergency caller ID and callback behavior.
- Support state-specific dispatchable-location requirements.
- Export location records and audit history on request.
Troubleshooting quick guide
- Wrong 911 answering center: compare delivered address, registered location, provider route, and 911 answering center jurisdiction.
- Wrong room/floor: inspect endpoint assignment, network discovery, and facilities naming.
- Failed callback: review emergency caller ID, masking, inbound routing, and auto attendants.
- No internal alert: test webhook/email/SMS delivery and security bridge process.
- Remote user failure: verify prompt, saved location, VPN path, and user support instructions.
