Loadshedding & VoIP
Your cloud phones need two things to work: power and internet. Loadshedding kills both. Here's how to keep your business connected through every stage.
The Problem
When stage 6 hits and you're on battery backup, your fibre ONT dies (no power), your router dies, and your desk phones go silent. Even with a UPS on the router, most offices get 30-60 minutes max. Then everything goes dark.
The Solution: Layered Backup
You need three layers to stay connected through extended outages:
UPS for Router + ONT
Keeps fibre alive for 1-2 hours. Minimum 1500VA for most home/office setups.
LTE/5G Backup Link
When fibre dies completely, your phones switch to cellular. Dual-WAN failover handles this automatically.
Mobile App Fallback
If the office is completely dark, staff can answer calls on their手机 via the VoIP mobile app. Calls keep coming in.
UPS Sizing Guide
Don't guess, calculate what you actually need:
| Equipment | Typical Watts | Runtime on 1500VA |
|---|---|---|
| Fibre ONT | 12-18W | ~4 hours |
| Router (business) | 20-40W | ~2.5 hours |
| PoE switch (8-port) | 60-120W | ~1 hour |
| IP desk phone | 5-12W each | ~5 hours |
Tip: A 1500VA UPS covering router + ONT + 1 phone gives you roughly 2-3 hours of connectivity. For full office coverage, you need 3000VA+.
Dual-WAN Failover, The Real Fix
A UPS buys you time, but dual-WAN failover keeps you connected indefinitely. Your primary fibre goes down → router automatically switches to LTE/5G → calls keep working. No manual intervention, no downtime. We configure this for every client as standard.
