Developers are giving their AI agents a voice — here's what they're saying.
It was incredibly easy to set up in Hermes. I saw someone post an article about AgentLine and Prava and fed Hermes the article. She had it all set up and told me exactly what to do on my end to finish the setup. That really is the way to go. I probably wouldn't have had time to mess with it otherwise.
had my agent calling me in like 10 minutes. insanely easy

Frequently Asked Questions
How do I connect an AI agent to a phone number?
Connect AgentLine through MCP, the agent skill, or the REST API. Create a phone agent, set its instructions, fund the account, and provision a US number for $2.00/month. It can make and receive calls at $0.10/min. Your runtime needs access to the connected tools or API; a live link to its private context uses the relay or a webhook.
What countries are supported?
US numbers only.
How does voice calling work?
AgentLine's hosted voice agent handles the conversation using your instructions and saves the transcript. Connect your own runtime through the relay or a webhook when a call needs a live lookup or task. A hosted call does not require your runtime to generate every spoken reply.
What's the difference from Twilio?
Twilio is a general-purpose telecom API. AgentLine is purpose-built for AI agents — unified webhooks, automatic transcription, skill-based installation, and a relay architecture that doesn't require you to manage WebSocket streams.
Can I use my existing phone number?
No, You can only use the numbers purchased using agentline.
How do I handle incoming calls?
Ask your AI agent to handle incoming calls in the way you want it to handle.
How do I get a phone number for my AI agents?
Sign up at agentline.cloud and provision a US number for $2.00/month. The same number handles outbound calls, inbound voice, and inbound SMS ($0.02 per message). Works with OpenClaw, Hermes, and any agent that can follow the skill.
Are there ready-made voice agent templates?
Yes. Clone a working sales, support, healthcare booking, legal intake, home services, real estate, salon, insurance, scheduling, 2FA, after-hours, or recruiting agent at agentline.cloud/build. Each template includes the system prompt plus Python and Node code.
