Here's a question I get from developers building AI agents all the time: My agent can handle text, can it handle phone calls?
The short answer is yes. But most AI agents today are stuck in text-only mode. They can write code, answer questions, generate content - but they can't pick up a phone when a customer calls. That's a real gap that limits what your agent can do.
In this guide, I'll walk you through exactly how to give your AI agent a real phone number - one that can make outbound calls, receive inbound calls, and handle SMS. We'll use AgentLine as the telephony layer, and the whole process takes under 10 minutes. No telecom expertise required.
Why Would You Even Want This?
Text is great. But phone calls unlock something different:
- Real-time support - Customers can call in and get immediate answers, no ticket queue
- Accessibility - Not everyone wants to type. Some users just want to call
- Alerts and notifications - Your agent can call you when something important happens
- Higher conversion - Outbound call follow-ups after signups consistently outperform email
When we launched AgentLine, we talked to dozens of teams building AI agents. Almost all of them had hit the same wall - their agent could do everything in text, but couldn't handle a simple phone call. That's the problem we built AgentLine to solve.
