How It Works

From Sign-Up to Live Calls in 48 Hours

Three steps. No hardware. No IT team. No disruption to your current phone system.

1

Connect Your Phone Line

Keep your existing business number. We layer Caliber on top of your current phone system — no new hardware, no switching carriers, no downtime. Your team can still answer calls manually whenever they want. Caliber only picks up when they don't.

Works with landlines, VoIP, cell phones, and virtual numbers. Compatible with RingCentral, Vonage, Grasshopper, Google Voice, and all major carriers.

We Train Your AI Agent

Our team configures your AI receptionist with everything it needs to represent your business: your services, pricing, hours, FAQs, booking calendar, and call routing preferences. The agent learns your business in hours, not weeks.

You review and approve every response before going live. We handle the setup — you just answer a few questions about your business and we do the rest.

Go Live in 48 Hours

Your AI receptionist starts answering calls immediately. Every lead is captured, every appointment is booked, and every common question is answered — 24 hours a day, 7 days a week, 365 days a year.

Real-time call transcripts, analytics dashboard, and instant notifications. You see exactly what your AI receptionist is doing at all times.

Common Questions

Most can't tell. Our voice synthesis is indistinguishable from a human receptionist. The AI introduces itself naturally and handles conversations with the same warmth and professionalism your best employee would.

Caliber seamlessly transfers to your team in real time. It recognizes when a caller needs a human — complex negotiations, emotional situations, or specific requests outside its training — and routes the call with full context.

Completely. You control the greeting, tone, FAQ responses, booking flow, and escalation rules. We configure everything during setup, and you can adjust anytime from your dashboard.

Nothing changes. Your number stays the same. We add a forwarding layer so calls route through Caliber first. If you ever cancel, your phone system goes back to exactly how it was.

Most businesses are fully live within 24-48 hours. Complex setups with multiple locations or custom integrations may take 3-5 business days. The $299 setup fee covers everything.

No contracts, no commitments. Month-to-month billing. Cancel anytime from your dashboard. Your 3-day free trial starts with zero credit card required.
