Why teams connect Aircall and Freshsales

Keep Freshsales 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.

Freshsales 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 Deals, Tasks, Appointments, Notes in Freshsales with Numbers, Tags, Teams, Messages (SMS/MMS) 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 Freshsales. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Push product-qualified leads from the warehouse into Freshsales as contacts with lifecycle stages set.
  • 02 Keep Freshsales accounts aligned with a billing system so plan and revenue fields stay current.
  • 03 Send outbound SMS/MMS through the Messages API when a CRM or database record changes (appointment reminders, alerts) and write inbound replies back.
  • 04 Sync Tags and call dispositions onto matching CRM records as call outcomes so RevOps can report on conversation activity.

Common sync patterns

New contacts reachable right away

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

Where Aircall reaches out: contacts kept current

Names, phone numbers, email addresses, and the owning rep from Freshsales stay current in Aircall, so every call, text, or email goes to the right person at the right address.

Calls, messages, and meetings on the record

Activity handled in Aircall appears on the matching contact and account in Freshsales, so the next person sees the full history without leaving the CRM.
