Telnyx Voice AI vs CallForMe: build your own caller?
Short answer: Telnyx sells the parts to build a voice agent: a $0.05 per minute voice engine, language model tokens and telephony at carrier cost, about $0.06 a minute in Telnyx's own estimate. You build the agent, its prompts, phone-menu handling and the bridge to your AI. CallForMe is that caller already built for Claude, ChatGPT, Cursor and other agents, at $1 per answered call with no setup.
What you'd build
To have your AI agent call businesses on Telnyx yourself, you need:
- A Telnyx account, a voice assistant, and a prompt that handles openings, phone menus, hold, voicemail and wrap-up.
- A phone number and caller ID that businesses will pick up.
- A way for the voice assistant to ask your own agent (Claude, ChatGPT, Cursor) a question mid-call and wait for the answer.
- Something that turns the transcript into structured answers your agent can use.
- Guardrails: AI disclosure, blocked numbers (emergency, premium), per-number call caps and an opt-out list.
- A bridge to your agent: an MCP server or an API.
CallForMe is that stack, already built.
