# Retell AI DIY vs CallForMe

> CallForMe runs on Retell. If you build your own caller on Retell, you pay roughly $0.11 per minute and handle the prompts, phone numbers, mid-call logic, and compliance yourself. CallForMe packages all of that for your agent at $1 per answered call, with no setup.

## What you'd build

To have your agent call businesses on Retell yourself, you need:

1. A Retell account, a voice agent, and a prompt that handles openings, phone menus, hold, voicemail, and wrap-up.
2. A phone number with good caller ID hygiene, so businesses don't see "spam likely".
3. A way for the voice agent to ask your own agent a question mid-call and wait for the answer.
4. Something to turn transcripts into structured answers your agent can use.
5. Guardrails: AI disclosure, blocked numbers (emergency, premium), per-number call caps, and an opt-out list.
6. A bridge to your agent: an MCP server or an API.

CallForMe is that stack, already built.
