Preparing a backup route when the phone service fails

Choose a mobile number that staff can answer if the main phone service fails, and make sure customers can find it before an outage. This is a manual fallback: callers use the backup number rather than being automatically redirected from the business number.

Write the route down in one record. Include the main business number, backup mobile number, outage trigger, primary and alternate responders, service provider fault contact, escalation contact, activation steps and restoration steps.

Cover each failure separately: office power, internet access, cloud calling service, a handset and staff absence. A charged mobile may help, but it still depends on the mobile network, which can also be unavailable or congested.

If you want calls to the main number automatically forwarded, ask your service provider whether the service supports it, how to switch it on and off, and what happens if you cannot access the usual administration connection. Record the provider’s exact instructions; do not assume a forwarding code or feature.

For an nbn service, contact your service provider about faults and service arrangements; nbn is a wholesaler and does not sell directly to businesses. Record the provider’s fault-reporting steps and expected response time, and ask whether forwarding or keeping a special business number involves charges.

Give staff a short response procedure: identify the business, take the caller’s request and assign someone to follow it up. Tell customers where to call if the main service is unavailable, using a contact channel that remains available during the outage.

Test the plan with the provider. From outside the business, call the published number and check any documented voicemail or diversion; then call the backup mobile number and confirm the assigned responder can answer and record a request. The test passes when staff can reach the caller using the backup route without relying on the failed service.

Do not test by calling 000. For an emergency, call 000; if the initial call does not connect within around five seconds, hang up and try again immediately. On subsequent attempts, stay on the line for up to 60 seconds.

When service returns, check that any diversion is removed, assign an owner to missed requests and update the route record when numbers, providers or key staff change.
