Buy and assign AI phone numbers

Purchase dedicated AI phone numbers by area code and assign them to your voice agents.

AI phone numbers in Centerfy are dedicated lines for your AI voice agents. You purchase them directly from the Phone Numbers page in the sidebar, choose an area code, check the number’s reputation, and assign it to an agent.

Buy a phone number

1. Open Phone Numbers

   Click Phone Numbers in the sidebar.

2. Choose an area code

   Click Buy Number. Enter the area code you want and browse available numbers.

3. Check reputation

   Before purchasing, check the number’s spam reputation to avoid numbers that have been flagged by carriers.

4. Purchase the number

   Click Purchase. The number is active immediately.

Assign to an AI agent

1. Select the number

   From the Phone Numbers list, click the number you just purchased.

2. Assign an agent

   Select the AI voice agent from the dropdown. Save your changes. All inbound calls to that number now go to the assigned agent.

Platform calling and SMS

For non-AI platform features like manual SMS, bulk messaging, and platform calling, you need a separate number connected through a telephony provider:

• Go to Settings > Integrations
• Connect Twilio or Telnyx with your account credentials
• Import your business number from that provider

This is required because platform messaging must comply with TCR (The Campaign Registry) regulations and A2P (Application-to-Person) carrier requirements. AI-dedicated numbers are not registered for these purposes.
