Live in three steps
Install from the HighLevel App Marketplace
Pick the accounts you want, approve the permissions, done. Takes about a minute.
Connect Aircall
Click Connect with Aircall and approve Syncline on Aircall's own sign-in screen. The wizard sets up the webhook and loads your numbers — no API keys. Setup help is free on every plan; contact support if Aircall's approval screen does not complete.
Map numbers and verify a call
Choose the HighLevel location for each Aircall number, save the mapping, and place a test call. Check its record and outcome tag, then verify your intended workflow runs once.
What Syncline does
Every call, logged in seconds
Inbound and outbound Aircall calls land on the right HighLevel contact as native call records — answered, missed, or voicemail — moments after the call ends.
Outcomes that fire your workflows
Records carry real outcomes: completed, no answer, or voicemail. Syncline also tags the contact with the outcome — so a Contact Tag workflow trigger runs your missed-call text-back, follow-up sequence, or pipeline update within seconds.
Recordings and duration attached
Call records include duration and a recording link when audio is available from Aircall, in the conversation timeline where your team already works.
No call is ever orphaned
Unknown callers become contacts automatically — with their phone number — so every conversation has a home from the very first ring.
Self-serve number mapping
The setup wizard pulls your numbers from Aircall and maps each one to the account you choose. Unmapped numbers raise loud alarms instead of silently dropping calls.
Built for agencies
Install across your client locations and map each Aircall number to the HighLevel account that should receive its calls.

Questions, answered
Does the free trial charge me?
Every plan starts with a 14-day free trial. HighLevel asks for a payment method at install, but nothing is charged until the trial ends — and you can uninstall any time before then.
Do you charge per call?
No. Syncline's call logging has no per-call fees. Plan pricing and trial terms are shown in the HighLevel marketplace before you install.
Does Syncline send SMS or include AI summaries?
No. Syncline supports call logging, recording links, and outcome tags. Aircall SMS/MMS, transcripts, and AI summaries are not supported. A text-back workflow uses your own HighLevel messaging service, whose charges still apply.
Can HighLevel workflows react to these calls?
Yes. Syncline writes true call records through HighLevel's conversation provider system, and it tags the contact with the call outcome — syncline-missed-call, syncline-answered-call, or syncline-voicemail. Build workflows on Contact Tag → Tag added for these tags. Do not use the built-in Call Status trigger for Syncline records. The tag is removed automatically a minute later, so the next call fires your workflow again.
I'm switching from another Aircall integration. How painful is it?
Map your numbers in Syncline and verify a test call and its workflow before retiring the old logger. During any overlap, check for duplicate records and automations. If you depend on the old app for SMS or other features Syncline does not support, keep those covered before switching. The switch guide walks through the steps.
What does Syncline access in my account?
Five narrow permissions, used for exactly what you see: reading conversations, writing call records, reading contacts, creating/updating contacts for unknown callers, and reading your account names so setup is crystal clear. Details in our privacy policy.
