What is a Failover Phone Number?

New On-Call & Operations Published

A Failover Phone Number is a secondary destination used by an incident management system if the primary on-call responder cannot be reached. For example, if the system tries to call the primary engineer and they don't answer within 30 seconds, the call is "failed over" to a backup engineer or a third-party answering service to ensure the caller isn't left hanging.

Key Benefits of Failover Numbers

  • Guaranteed Human Connection: Ensures that a caller eventually reaches a human, even if the primary responder has a technical or personal issue.
  • Redundancy: Protects the company's reputation by ensuring no "emergency" call goes into a black hole.
  • Tiered Support: Can be used to route calls to an "overflow" team during peak incident volumes.

You can set up "multi-stage" routing where the call rings the primary responder first, then waterfalls to the next responder of the team, and finally to a manager or a voicemail-to-incident workflow. All Quiet ensures that every caller has a path to resolution, no matter what.
