Why teams connect Aircall and Twenty CRM

Keep Twenty CRM and Aircall working from the same contacts, and log every call, message, and meeting back on the record, in real time and in both directions.

Twenty CRM holds the people the business talks to: the contacts, their phone numbers and email addresses, and which rep owns the relationship. Aircall is where the talking happens, whether that is calls, texts, email, or meetings. The two depend on the same people, and when the contact list in one drifts from the other, outreach goes to stale numbers and the record of what was said never makes it back to the account.

Stacksync syncs Notes, Custom Objects, Attachments, Workspace Members in Twenty CRM with Tags, Teams, Messages (SMS/MMS), Webhooks in Aircall field by field, in real time, and in both directions. Current contact details flow out to Aircall so it can reach the right person, and the calls, messages, and meetings Aircall produces flow back onto the matching record in Twenty CRM. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Mirror support tickets or tasks between Twenty and an operations tool.
  • 02 Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
  • 03 Provision and deprovision Users and Team membership from an HR system or IdP so the agent roster, seats, and routing groups stay current.
  • 04 Send outbound SMS/MMS through the Messages API when a CRM or database record changes (appointment reminders, alerts) and write inbound replies back.

Common sync patterns

Where Aircall sends at scale: delivery and reply status back on the contact

Sends, bounces, opens, and replies from Aircall update fields on the contact in Twenty CRM, so lead status reflects what actually reached the person.

One contact list, opt-outs included

A number, address, or unsubscribe recorded in either system updates the other, so no one calls a disconnected line or messages someone who opted out.

New contacts reachable right away

A contact created or updated in Twenty CRM appears in Aircall within seconds, so outreach starts without exporting a list or re-keying numbers.
