How does AgentZap block spam and robocalls?
AgentZap screens every incoming call against known robocaller and spam patterns and filters the bad ones before they reach you. Real callers go straight through, and you can add your own allowlist of numbers that should always ring.
Is spam blocking free?
Yes. Spam and robocall filtering is included on every plan at no extra cost, and filtered calls do not count against your monthly minutes. You only pay for the real conversations.
Will it block real customers by mistake?
That is the risk everyone worries about, so the filter is built to favor letting calls through. You keep an allowlist and a VIP list of numbers that always ring, and anything the AI is unsure about is answered rather than dropped. You can review what was filtered at any time.
How does it know which calls are spam?
It checks the calling number against large, constantly updated lists of known robocallers and spam sources, plus the behavior patterns that scam calls share. To put the scale in perspective, US phones received about 52.5 billion robocalls in 2025 (YouMail Robocall Index).
How is this different from carrier or STIR/SHAKEN protection?
STIR/SHAKEN is a carrier standard that authenticates caller ID so a number is harder to spoof. It verifies who is calling, but it does not answer or screen your calls, and it has gaps on older networks. AgentZap adds a screening layer on top: it actually handles the call, filters the spam, and helps the real caller.
Can I choose numbers that always get through?
Yes. Add regular customers, partners, or your own team to an allowlist or VIP list and those numbers always ring through, even if a number pattern would otherwise look unusual.
Does filtering slow down real callers?
No. Real callers are answered on the first ring like normal. The filtering happens instantly, so a legitimate caller never waits while spam is sorted out.
Does it work with my existing business number?
Yes. Keep your current number by forwarding it, or port it to AgentZap for free. Filtering works either way. See dedicated number and porting.
Why does blocking spam matter for my business?
Spam wastes your team's time and trains people to ignore the phone. It also feeds caller distrust: 74% of consumers say they avoid answering calls from unknown numbers, yet 79% still consider the phone important for reaching a business (TransUnion, 2024). Clean lines keep your team focused on real customers.
