Spam and robocalls are getting worse — and they target business numbers hardest

Phone numbers listed publicly on Google, directories, and websites attract disproportionate volumes of automated calls. Cold callers, automated survey diallers, PPI bots, and silent spam systems all target business numbers — often multiple times a day. Each interruption costs time, breaks concentration, and eventually makes you less likely to answer unknown numbers at all.

The risk: you stop answering unknown callers, and a real customer with a new enquiry goes to voicemail — or worse, hangs up and calls your competitor instead. The only way to solve both problems is to let AI make the call before your phone does.

AI that stops spam before your phone rings — on every call

CallCenturion’s IsHuman Check™ analyses every inbound call in real time. Robocalls are identified and terminated immediately. Genuine callers are forwarded to your phone — so you can answer with confidence knowing it is always a real customer.

Robocalls stopped before your phone rings

Automated callers are detected and terminated before the forward is placed. Your phone does not ring for spam — you only hear it ring for real customers.

IsHuman Check™ — real-time detection

Our patented system assesses each call in real time, looking for the signals that distinguish automated diallers from real people. Detection completes in under two seconds.

Genuine customers pass through seamlessly

Real callers who clear screening are connected to your mobile without noticeable delay. The caller experience is professional and uninterrupted.

Sensitivity you control

Adjust how aggressively the system screens — from cautious (only clear robocalls blocked) to strict (all borderline calls screened out). Change it any time from your dashboard.

Always on — including out of hours

Spam protection is active 24 hours a day, seven days a week. Robocalls are blocked even when your business hours are over and forwarding is switched off.

See every blocked call in your dashboard

A complete log shows you every blocked, forwarded, and messaged call with timestamps. See exactly how much spam is being caught on your business number.
