Stop answering calls from people you don't know.
ZAVoiceAI picks up first. It asks who's calling and why in a short, natural conversation — then rings your phone only if it's worth taking, or leaves you the transcript if it's not.
Your number is public. Everyone with a dialler knows it.
Once a number is on an invoice, a listing, a form, or a "please call me," it ends up in call centre lists you never agreed to. Most of what comes through isn't for you — it's for whoever answers.
South African numbers took an estimated 17.47 billion spam calls in the first half of 2026 alone — up 25% on the year before, putting the country among the five most spammed in the world. Truecaller Insights, 2026
Cold sales and insurance calls
Funeral cover, solar, timeshare, "your vehicle's warranty" — the same scripts, several times a week, from numbers you've never saved.
Scam and spoofed numbers
SIM-swap attempts, fake bank security lines, "OTP" pressure calls — the ones that count on you answering without thinking.
Calls you can't take right now
In a meeting, on the road, or just not free — and no way to know if this one was actually worth interrupting for.
Three steps. No new number, no new SIM.
ZAVoiceAI sits between your carrier and your phone using standard conditional call forwarding — the same feature your network already offers.
Turn on conditional forwarding
Dial your network's forwarding code once — something like *61*+27...# — so calls you don't answer route to ZAVoiceAI instead of voicemail. Takes under a minute, and you can switch it off the same way.
Unrecognised numbers get answered
ZAVoiceAI greets the caller in your own words, asks who they are and why they're calling, and holds a short, natural conversation — not a menu, not a beep.
You get the call, or the transcript
Numbers you've marked as trusted ring straight through, no screening. Everyone else gets a transcript you can read live, and you decide whether to jump in, call back, or let it go.
What's actually in the app
No filler settings. Every feature below is built to change how a specific call plays out.
Live call screening
An AI receptionist answers on your behalf and finds out who's calling before your phone ever rings.
Trusted numbers
Family, close contacts, work — anyone on your list bypasses screening completely and rings straight through.
Live transcript
Watch the conversation appear as it happens. If it turns out to matter, take the call over mid-screen.
Custom greeting
Write what your receptionist says when it picks up. Sound like your business, your household, or just yourself.
Transfer number
Route a screened call to a colleague, partner, or assistant when you genuinely can't take it yourself.
Keep your existing number
Runs on carrier-level call forwarding on the SIM you already have. Nothing to port, nothing new to give out.
The actual app, screen by screen
No mockups — this is ZAVoiceAI running in Internal Testing right now, screening a real call over a real Twilio line.
Every screened call, with a transcript and a one-tap call-back.
The forwarding setup, explained in plain language, done once.
Write your own greeting and pick where screened calls go.
Clear plans, billed through Google Play, cancel any time.
Built for people whose number doesn't stay private
Agents and freelancers
Your number is on every listing, quote, and business card you've handed out.
Small business owners
The line that used to be quiet now takes ten sales calls a day.
Anyone tired of spam and scam calls
You want a real screen, not another blocklist app that misses half of them.
People who are just busy
You'd answer if you knew it mattered — you just don't know until it's ringing.
One plan to start. Upgrade if you need more control.
