Setting up an AI voice agent used to require months of development. Today, platforms like OpenVoice Agents let you go from zero to handling real calls in under 30 minutes.

A phone number (or we provide one)
Your business information (hours, FAQs, services)
About 30 minutes

Step 2: Configure Your Agent's Identity

Give your agent a name and voice. Choose from natural-sounding voices across genders and accents. Add your business name so the agent knows how to introduce itself.

Step 3: Build Your Knowledge Base

Your knowledge base is everything your agent knows about your business:

Business hours and holiday schedules
Services and pricing
Top 20 FAQs — answer them here
Escalation rules — when to transfer to a human

Upload documents, paste text, or type FAQs directly. The agent learns from all of it.

Step 4: Connect Your Phone Number

Get a new number instantly, or forward your existing business number to your agent.

Step 5: Test and Go Live

Use the built-in call simulator to test before going live. Refine the knowledge base, then activate. Your agent starts handling calls immediately — 24/7, from day one.

Step 6: Monitor and Improve

Your dashboard shows every call — transcript, duration, outcome, and caller sentiment. Review calls your agent struggled with and update the knowledge base.
