Emergency Services
How emergency calling works on interconnected voice service, and — importantly — the circumstances in which it will not work. Read this before deploying voice to end users.

Draft — not yet in force. This policy is published for review. It states how the network operates and what we intend to commit to, and it has not completed legal review. It does not yet form part of any agreement.
- 01
How it works
Emergency calls from interconnected voice service are routed to the emergency answering point serving the registered service address of the calling endpoint.
The registered address, not the physical location of the device, determines where the call is routed and what address is presented to the responder.
- 02
Registering an address
You must register a valid service address for every endpoint before it is used, and update it whenever an endpoint moves. Addresses are registered through the API or the console and take effect on validation.
An endpoint with no validated address may be blocked from placing calls, because a call that cannot be routed to a responder is worse than a call that fails immediately.
- 03
Limitations you must disclose to your users
Emergency calling does not function during a power failure at the customer premises, or during loss of internet or network connectivity, unless a failover path is configured and available.
If an endpoint is used at a location other than its registered address, the call is routed to the registered address and responders may be dispatched to the wrong place.
Emergency calling may be unavailable during network maintenance or outage.
Some jurisdictions do not support emergency calling from interconnected voice service at all. Coverage is stated per country in the documentation.
- 04
Your obligation
You must advise your end users of these limitations, obtain their acknowledgement, and place warning labels on equipment where the applicable regulator requires it.
