Insights on AI agents, phone infrastructure, and building with AgentCall.
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.
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.
AgentCall launched on Product Hunt today. Provision real US/Canada numbers, send SMS, extract OTPs, run AI voice calls in 31 languages, and give your agent cross-call memory. Free tier, no card required.

AgentCall now speaks 31 languages on inbound and outbound AI voice calls (English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, Korean, Chinese, Hindi, Arabic, Russian, Indonesian, Turkish, Polish, Ukrainian, Vietnamese, and more, plus auto-detect).

Spellar, Otter, and Fathom build cross-meeting memory into their product. AgentCall plus Hermes does the same thing for phone calls, except your own agent owns the memory. Includes a working end-to-end demo and one real implementation gotcha.
Most AI phone agents forget every call the moment you hang up. This walks through how to give an agent like Hermes a real phone number, load today's context onto every inbound call, and feed the transcript back into the agent so tomorrow's brief references yesterday's conversation. With concrete use cases for solo founders and small teams.
