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.”

How to Text Your Own AI Agent on a Real Phone Number [2026]
Point a real US or Canada number at your own agent with relay mode. AgentCall runs no AI of its own: it signs every inbound text to your webhook and delivers your agent's reply, with no timeout to fight on slow turns. One API call on our side, and one command installs the open-source relay next to your agent.
Read more →AgentCall vs AgentPhone: Which Phone API for AI Agents? [2026]
AgentPhone is cheaper per AI voice minute and has iMessage. AgentCall ships a hosted MCP server, cross-call memory, and a hosted AI that can call your tools. An honest side-by-side with real pricing, a worked monthly example, and the cases where AgentPhone is the better buy.

Caller memory is available on Free and Pro within the account's voice allowance. New trials have five inbound AI minutes total over 72 hours; existing Free accounts retain their assigned monthly offer. Stored memory remains available after a trial ends. Memory does not add a separate usage fee.
