Aircall allows you to connect phone numbers to your integrations with flexibility so your workflows remain efficient. Although there is no hard limit, there are recommended guidelines to maintain strong performance.

Recommended limit

Aircall suggests connecting no more than 200 to 250 phone numbers to a single integration. Staying within this range helps prevent performance issues and keeps your integration responsive.

Connecting more than 250 numbers

If your setup requires more than 250 numbers, you can distribute the load by creating additional connections to the same integration.

Steps:

  1. Create extra integration connections.
    For example, set up separate connections for each team, region, or business unit in your CRM or Helpdesk tool.
  2. Review your workflow to determine whether grouping numbers into specific integration instances provides a better operational structure.
  3. Allocate numbers across the new connections to keep each one within the recommended range.
Tip: Organizing integrations by team or region often simplifies management and improves performance.

Why this is recommended

Although Aircall does not enforce a strict limit, connecting too many numbers to a single integration may:

  • Slow down data synchronization
  • Affect real time updates such as call logs or activity tracking
  • Delay automated processes triggered by the integration

Following the recommended range helps ensure your connected tools remain fast and reliable.
