# Phone & Voice

Check who is behind a number, or have a call placed for you

## What this does

Someone gives you a phone number and you need to know whether to trust it, or you need a call made. This checks the carrier behind a number and flags SIM-swap fraud signals, and can place AI voice calls or get you a number of your own. Payment happens automatically from your wallet.

### Top 3 things it does for you

- Look up who carries a phone number
- Check a number for SIM-swap fraud signals
- Rent or buy a phone number

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Phone & Voice

This verifies phone numbers, returning carrier information and SIM-swap fraud signals, and places AI-powered outbound voice calls through BlockRun's gateway, built on Twilio and Bland.ai.

It triggers when you ask to look up a number, check its fraud risk, buy or rent a phone number, or place an AI voice call. Payment is handled automatically via x402 from the wallet, so there is no separate purchase step.

## Questions

### Is Phone & Voice safe to install?

AIR scanned this exact version of Phone & Voice and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 6d25be5aa893, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/phone.

### How do I install Phone & Voice?

Open https://airmarket.ai/app/phone on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/BlockRunAI/ClawRouter/tree/6d25be5aa8934cdcb54738d55fdd2063309b9b44/skills/phone. Install from that link, not the branch.
