Migrate from Aircall to JustCall Without Disrupting Your SDR Team

The moment most teams decide to leave Aircall is not a dramatic outage. It is a quiet Tuesday when the CFO pulls the renewal invoice, notices the per-seat cost climbing north of $50/month, and asks whether the team is actually using the AI features they are paying for. I have been in that meeting three times now. The answer is almost always no. What follows is the migration playbook I use at Homegrown Growth Co. to get SDR teams off Aircall and onto JustCall without a single missed call.

Before you migrate

Do not touch your JustCall account until you have completed the prep checklist below. Skipping even one item is how teams end up re-entering two years of call history by hand. I have seen it happen. It is painful, it is preventable, and there is no excuse for it.

• Export your Aircall call logs. Go to Analytics > Call Details, set the date range to your full account history, and export as CSV. Do this for every team workspace. Aircall caps exports at 10,000 rows per pull, so segment by quarter if your volume is high.
• Download call recordings. There is no bulk API. Use the Aircall API endpoint GET /v1/calls with a Zapier loop (or a simple n8n HTTP node) to hit each recording URL and pipe files to S3 or Google Drive. My preferred setup: a Zapier multi-step zap that triggers on each call record row, downloads the audio URL, uploads to Drive, and logs the Drive link to a tracking sheet.
• Document your CRM integration mappings. Screenshot or export every field mapping in Aircall’s HubSpot or Salesforce connector. JustCall maps fields differently by default and you will lose your custom disposition-to-deal-stage logic if you do not write it down first.
• List every active number. Export your number inventory from Aircall’s Numbers settings page. Flag which numbers are on live campaigns, which are sitting in email signatures, and which handle inbound routing.
• Pause or notify active sequences. If you are running outbound sequences in Outreach, Salesloft, or a similar tool that dials through Aircall, pause those steps now. Re-activate them only after JustCall is verified live.
• Confirm your Aircall contract end date. You need at least 10 business days of overlap before renewal to port numbers without a gap. If you are within 10 days of renewal, request a 30-day extension before initiating the port.

Migration steps

What breaks and what does not transfer

Most of the migration is mechanical and predictable. The things that actually bite teams are subtle. Do not skip this section just because the steps above felt manageable.

# JustCall outcome tag config example
# Settings > Call Outcomes in JustCall dashboard

outcome_tags:
  - id: vm_left
    label: "Voicemail Left"
    crm_disposition: "Left Voicemail"
    next_step: "Auto-enroll in SMS follow-up sequence"

  - id: not_interested
    label: "Not Interested"
    crm_disposition: "Closed Lost"
    next_step: "Move to nurture list"

  - id: callback_requested
    label: "Callback Requested"
    crm_disposition: "Follow Up"
    next_step: "Create task in CRM, due +1 business day"

  - id: connected_demo_booked
    label: "Demo Booked"
    crm_disposition: "Meeting Scheduled"
    next_step: "Trigger deal creation workflow"

# Map each Aircall freehand tag to one
# of these structured outcomes before cutover.
# Do not leave unmapped tags in your export CSV.

What transfers cleanly: Your phone numbers (via porting), your team user list (re-invite by email), your CRM contact data (it lives in your CRM, not Aircall), and your SDR muscle memory. The JustCall dialer UI is familiar enough that ramp time is under a day for most reps.

What does not transfer: Call recordings (manual download required), call tag history, dashboard benchmarks, and any Aircall-specific Zapier or webhook automations. Rebuild those against JustCall’s webhook schema, which is well-documented in the JustCall developer docs.

Verify it worked

Do not call the migration done until you have confirmed all four of these. Seriously. I have watched teams declare victory and then discover a logging gap three weeks later when pipeline reporting looked wrong.

1. Make a test call from JustCall and confirm it logs to your CRM with the correct contact association, call duration, recording link, and outcome tag.
2. Send a test SMS from JustCall and confirm it threads in both the JustCall inbox and the CRM contact timeline.
3. Trigger a voicemail drop on a test contact and confirm the audio plays correctly and the outcome tag fires.
4. Pull a one-week activity report in your CRM after cutover and verify call volume and outcome distribution match your pre-migration baseline. If the numbers look dramatically different, you have a logging gap, not a performance problem.

If you have HubSpot automations that branch on call dispositions, specifically check those workflow enrollment triggers. They are the most common silent failure mode after a dialer switch. According to HubSpot’s integration documentation, workflow re-enrollment criteria do not automatically update when the underlying property source changes, which is exactly what happens when you swap dialers.

Should you switch, or is there a better Aircall alternative for your team?

Choose JustCall if

• You want AI call scoring and SMS sequences without a separate tool
• Your team is 3 to 50 seats and price sensitivity is real
• You need solid HubSpot or Salesforce two-way sync out of the box

From $29/seat/month Try JustCall →

Choose KrispCall if

• Your team is internationally distributed and needs global number coverage
• You want a simpler setup with fewer configuration options
• Budget is the primary driver and call volume is moderate

From $15/seat/month Try KrispCall →

Choose Aloware if

• You run high-volume outbound and need a power dialer with DNC compliance baked in
• Your sequences live in HubSpot and you want the dialer embedded directly in the CRM
• Your team dials 80 or more calls per rep per day

From $30/seat/month Try Aloware →

Choose Aircall if

• You are on an enterprise contract with Aircall and switching costs exceed savings
• Your team relies on Aircall's Intercom or Front integrations with no JustCall equivalent
• You have a dedicated Aircall CSM and the relationship is delivering real value

From $40/seat/month Stay on Aircall →

Do the migration in the next sprint

An Aircall-to-JustCall migration is one of the highest-ROI infrastructure swaps a RevOps team can run this year. The playbook is straightforward: export before you touch anything, port your numbers first, rebuild your CRM mappings with intention, run parallel for one sprint, and verify with four concrete checks before you cancel. According to G2’s VoIP category data, JustCall consistently ranks above Aircall on ease of setup and quality of support, which tracks with what I see when I run this migration.

The biggest risk is not the migration itself. It is waiting another quarter because it feels complicated. It is not. KrispCall and Aloware are worth a look if your situation matches those profiles above, but for most B2B SaaS SDR teams, JustCall is the pragmatic call.
