Hosted VoIP, Microsoft 365, accounting software, and point-of-sale systems all depend on a working internet connection. A single line that drops during business hours can stop calls, sales, and work across the office. The fix is redundancy — and it is more affordable than many businesses expect.
Use two different connections
A second connection only helps if it fails independently of the first. Choose a different provider and, ideally, a different technology — for example fibre or cable from one provider plus a fixed wireless or mobile broadband connection from another. Two lines from the same provider over the same route often fail together.
Let a router switch automatically
A firewall or router with dual-WAN support detects when the main line fails and moves traffic to the backup in seconds, then switches back when it recovers. More advanced SD-WAN equipment can also choose the best path for voice calls in real time.
Protect the equipment from power problems
Failover is useless if the modem, router, and network switch lose power. Put them on a UPS sized to keep them running through short outages and allow clean shutdowns. It also protects them from damaging power surges.
Plan for voice specifically
- Prioritise voice traffic on your network with quality-of-service settings.
- Configure your phone system to send calls to mobiles or softphones automatically if the office goes offline.
- Test failover during a quiet period so you know how calls behave before a real outage.
Test it regularly
Unplug the main connection once a quarter and confirm that calls, cloud apps, and card payments keep working. Backup lines that are never tested have a habit of failing exactly when they are needed.
