WHY SWITCH NOW
South Africa is hanging up on the landline
Copper networks are being switched off, fibre keeps spreading, and voice has quietly become just another thing your internet does — better and cheaper.
1M+
Copper lines already retired
Telkom has decommissioned over a million copper lines since 2015. Analogue business telephony is being phased out, not upgraded.
3M+
Active fibre connections in SA
Fibre grew more than 20% in the past year alone — the infrastructure VoIP needs is already at your door, or an LTE signal away.
60%
Typical saving on call costs
Businesses moving from analogue lines to Othos VoIP typically cut call spend by up to 60% — with per-second billing doing much of the work.
THE NUMBERS
What a 10-user office really pays
Put your current phone bill next to VoIP and the decision usually makes itself. Here is the honest side-by-side.
TRADITIONAL LANDLINE SETUP
R5 000 – R15 000/m
Line rental of R200 – R500 per line, per month — before anyone makes a call
Per-minute billing, rounded up — a 61-second call costs you two minutes
On-site PABX hardware plus a maintenance contract to keep it alive
Tied to one address — move offices and you risk losing your number
VS
OTHOS BUSINESS VOIP
From R499/m
Month-to-month basis - no long term contracts
Pure per-second billing — R0.29/min to landlines, R0.39/min to mobiles
Nothing to maintain — your PBX lives in the cloud and updates itself
Your number goes where you go — office, home or the mobile app
Typical 10-user office. Landline figures reflect industry averages for line rental, metered calls and PABX maintenance; Othos figure is based on SMB Package for 10 users.
HOW IT WORKS
How business VoIP works — in plain English
No jargon, no new habits to learn. Four things happen every time someone calls — and only one of them is new.
1
You talk
Pick up your desk phone, laptop softphone or the Othos mobile app — it works exactly like a normal call.
2
Your internet carries it
Your voice travels over fibre, LTE or 5G as data, instead of down an ageing copper line.
3
Our cloud connects it
The Othos exchange, running on AWS infrastructure, routes your call to any network in the world.
4
They just answer
Customers see your normal 021, 011 or 031 number. On their side, nothing changes at all.
