Real calls. Real results.
Listen to how Callium handles real inbound calls — natural, confident, and never making things up.
The only AI voice agent with a
verified under-1% hallucination rate.
Most AI voice platforms hallucinate 3–15% of the time. That means your AI is confidently making up wrong prices, wrong hours, and wrong information to your customers. We fixed this.
What other AI says
~8% hallucinationWhat Callium says
<1% hallucinationHow we achieve <1% hallucination
Every Callium deployment is grounded using Retrieval-Augmented Generation (RAG). Before going live, we build a verified knowledge base from your actual business data — pricing, hours, services, policies, FAQs. The AI retrieves verified facts on every response. When it doesn’t know something, it says so honestly and escalates to you — it never invents an answer.
What makes Callium the most
reliable voice AI for SMBs.
We obsess over the problems other platforms ignore — hallucination, latency, and real-world deployment complexity.
Under 1% Hallucination
RAG-grounded responses pulled from your verified knowledge base. The AI only states confirmed facts — never fabricates prices, hours, or services.
Sub-400ms Response
Streaming pipeline processes speech recognition, reasoning, and voice synthesis in parallel. Under 400ms feels like a real human — no awkward pauses.
Done-For-You Setup
We handle everything — custom script writing, voice selection, CRM integration, testing, and launch. You focus on your business, we handle the AI.
Unlimited Concurrent Calls
Handle 10 or 10,000 simultaneous calls with zero performance drop. Cloud-native auto-scaling — no concurrency caps, no queues, no dropped calls.
Full Context Memory
Remembers every detail across the entire conversation and previous calls. Callers never repeat themselves — your AI gets smarter with every interaction.
Noise & Accent Resilient
Deep-learning noise suppression and accent-aware recognition. Works in busy offices, street noise, with non-native speakers — 95%+ accuracy in real conditions.
One AI platform.
Every voice workflow.
From inbound receptionist to outbound lead qualification — Callium handles every voice use case with vertical-specific intelligence.
24/7 AI Receptionist
Answer every call in under 3 seconds. Route inquiries, schedule appointments, and handle FAQs in 50+ languages — around the clock, including holidays.
Lead Qualification
Instantly call every new lead the moment they arrive. Score on budget, intent, and timeline — push hot leads to your CRM and book discovery calls automatically.
Appointment Booking
Integrate with Google Calendar, Calendly, or HubSpot to book, reschedule, and confirm appointments during the call — zero back-and-forth.
Customer Support
Resolve tier-1 and tier-2 support by voice, instantly. Handle complaints, order lookups, returns — escalate complex issues with full conversation context.
Outbound Campaigns
Run massive outbound campaigns — re-engagement, payment reminders, surveys. Engage thousands of contacts simultaneously with personalized conversations.
After-Hours Coverage
63% of SMB inquiries come after hours. Callium captures every lead, books every appointment, and answers every question — even when your team is offline.

Frequently asked questions
Callium deploys your AI employee across all major communication channels: phone calls (answered in under 3 seconds), WhatsApp, Telegram, SMS, and website webchat. All five channels share the same AI brain and knowledge base, so the experience is identical and consistent regardless of how the customer reaches out. Cross-channel memory means a caller on Monday and a WhatsApp message on Wednesday are treated as the same conversation.
Every Callium deployment uses Retrieval-Augmented Generation (RAG). Before launch, we build a verified knowledge base from your actual business data — pricing, hours, services, policies, and FAQs. Every AI response is grounded against this verified source. When the AI encounters a question outside its knowledge base, it says so honestly and escalates to you — it never fabricates an answer. This gives us a verified <1% hallucination rate vs the 5–15% industry average.
The setup fee covers everything needed to go live: a discovery call to understand your business, custom script writing, voice selection and configuration, knowledge base creation, CRM integration and testing, and a full go-live review. This is not a DIY platform — our team builds your AI employee for you. Most competitors charge $399+/mo with no setup included and expect you to build it yourself.
Standard deployments take approximately 2 weeks from the discovery call to go-live. This includes build time, testing, and your review round. If you need urgent deployment, rush deployment is available in 48–72 hours for straightforward use cases.
The AI is designed to recognize the boundaries of its knowledge base. When a caller asks something outside that scope, Callium politely acknowledges it, collects the caller’s contact details, and either transfers to a live agent or schedules a callback — depending on your configuration. It never makes up an answer.
Yes — we integrate with HubSpot, Salesforce, Zoho, GoHighLevel, Google Calendar, Cal.com, Zapier, and custom webhooks. All call data, lead scores, booking confirmations, and transcripts sync in real time. We handle the integration as part of the setup process.
Callium uses ultra-realistic voice synthesis with natural pacing, pauses, and intonation. It handles interruptions and manages turn-taking naturally. In blind tests, most callers cannot distinguish Callium from a live representative. We are also fully transparent — if a caller directly asks whether they’re speaking to AI, Callium confirms this honestly.
Yes. Medical clinic deployments include full HIPAA compliance with end-to-end encryption, secure data storage, and BAA agreements available on request. All deployments are SOC 2 Type II and GDPR ready. Industry-specific compliance is configured during the setup process.
