Phone Numbers for
AI Agents
Phone numbers, SMS, OTP extraction, AI voice, and cross-call memory. All in one API.
Works with MCP. Claude, Cursor, Windsurf, Hermes, OpenClaw.
New
Now with Auditable Call Memory
Every AI call gets extracted into a source-backed Call Report. When the same caller dials back, your AI starts with a one-paragraph brief of who they are and what was promised.
- Cross-call memory. Sarah called Tuesday. Friday, your AI picks up the thread.
- Auditable. Every entry quotes the transcript line behind it.
- Customer-controlled. On by default. Toggle off any time from the dashboard.

Brief
Called Tuesday asking about pricing for a 30-person team. You promised to send a quote by Friday. She mentioned a competitor demo on Thursday.
Source quote
"Yeah we're a team of about 30, can you send a quote by Friday? We've got a demo with another vendor Thursday."
How It Works
Three steps. Zero friction.
01
Get a number
Provision a phone number in seconds. Ask your AI agent via MCP, or hit the REST API directly. Pick country, area code, and capabilities.
02
Connect your agent
Plug AgentCall into Claude Desktop, Cursor, Windsurf, Hermes, OpenClaw, or any MCP client. One URL plus an API key. 60 tools and 5 prompts auto-discover.
03
Wire the loop
Optional context webhook so the inbound AI speaks with today's brief and priorities loaded. Transcripts, summaries, SMS, and OTPs flow back out to your webhook the moment they arrive.
AI Voice Calls
Pick a voice. Make a call.
Your agent speaks with the AI voice you choose, and returns a full transcript. Click to preview each one. Voices marked Premium are powered by ElevenLabs.

Loved by AI agent builders
“I asked Claude for voice agents — I was so frustrated with how technical setting up Twilio was, I figured someone smarter than me must've built an agent-first alternative.”
