Aircall Alternative for UK Businesses

The maths.

Three real-shape SME profiles. Aircall Essentials at £30/user (the most common UK price point) versus managed 3CX. The split-stack option keeps Aircall for the sales pod only.

Which path is right.

Two honest decision rules:

If the sales pod genuinely uses Aircall's sales-specific features — power dialer, CRM auto-logging, voicemail drop, call coaching playback — the split stack is the right answer. You keep the sales tool the sales team likes, you take the rest of the firm off sales-tool pricing. Typical saving: 50% of total telephony spend.
If the sales pod is using Aircall as just-a-phone — basic outbound calls, no power dialer, no CRM-disposition workflows — the full switch is the right answer. You weren't paying for the features you needed; you were paying for the brand and the polished UX. Typical saving: 70%+ of total telephony spend.

The scoping conversation we have at the start is exactly this question. Worth 30 minutes to find out which path matches your firm.

The "are we actually using the features" question.

The cleanest way to find out which path is right: ask your sales team three questions.

"Do you use the power dialer or progressive dialing modes in Aircall?" If yes — they're using a feature 3CX doesn't have natively. Split stack.
"Do you use voicemail drop?" If yes — same. Aircall keeps real value.
"How much time per week do you save on call disposition / CRM logging because Aircall auto-fills HubSpot or Salesforce?" If the honest answer is "more than 30 minutes per rep per week", that's £15 per rep saved on a £30 spend — fair value. Below that, the auto-logging probably isn't paying for itself.

If two of three answers come back "we don't really use that", you're paying for capability you don't consume. Full switch to 3CX is the right answer.

Switching mechanics — full switch.

Same 6–8 week template as any UK PBX migration. Numbers port from Aircall's underlying carrier to Gamma (your 3CX system's SIP provider), handsets get provisioned, training runs, cut-over weekend.

Aircall-specific points:

Aircall number ranges sometimes port slowly. Their numbers come from a handful of carrier relationships. The porting paperwork is clean but the time from LoA to actual port date is sometimes 4 weeks rather than 2. Plan for the longer window.
Aircall contracts usually run 12-month rolling. Easier early-termination terms than Vonage or RingCentral. Most firms cut over at renewal without penalty.
CRM integration migration is the real work. Your sales team's HubSpot or Salesforce setup probably has Aircall-specific workflows. 3CX has CRM integration but the workflow needs rebuilding — automation, dispositions, call types. Budget a fortnight of sales-ops time. Not technically hard; just attention-intensive.

Switching mechanics — split stack.

Easier than a full switch because Aircall keeps running for the sales pod throughout.

Week 1–2. 3CX deployment for non-sales users. Reception, accounts, partners, mobile, general office. New main switchboard number on Gamma SIP. Existing main numbers port from Aircall to Gamma over 3–4 weeks.
Week 3–4. Internal call routing between 3CX (general firm) and Aircall (sales pod) configured — typically via SIP gateway or via DID routing on the main switchboard.
Week 4–5. Aircall account downsized to sales-team-only seats. Removal of non-sales users from Aircall billing. Saving applies from the next Aircall invoice.

Net effect: sales team experience is unchanged; everyone else gets a normal office phone system; bill drops by half to two-thirds.

What about the dialer integration into HubSpot / Salesforce?

3CX integrates natively with HubSpot, Salesforce, Dynamics, Zoho, Pipedrive, Bullhorn, and others — click-to-dial, screen-pop, call logging. What 3CX doesn't have is Aircall's sales-disposition automation (automatic call category tagging, sentiment-tagged playback, structured call-outcome logging). If your sales-ops live on those features, that's the split-stack answer. If your sales team uses "click the number, talk, log a note manually", you've got parity on 3CX and the full switch is fine.

Common questions.

Our sales team really likes Aircall's UI. Can we keep it?

Split stack. Aircall stays. We deploy 3CX for the rest of the firm. Sales-team experience: unchanged. Bill: down by 50%.

What's the international calling situation?

3CX through Gamma supports outbound to virtually every country at competitive per-minute rates. Aircall's international rates are sometimes lower per-minute for specific countries because of their direct carrier relationships in those markets. If you have heavy volume to a specific country, worth the comparison. We'll model it at the scoping call.

We use Aircall numbers in 20 countries. What about those?

That's a Vonage-pattern question more than an Aircall-pattern one. If you genuinely need 20-country DID footprint, Aircall (or Vonage, or RingCentral) is the right product category. 3CX through a UK partner is built for UK-centric operations with international as an add-on, not international-first. Stay on Aircall or look at Vonage.

What if our sales team grows? Does the split stack break?

No. The Aircall seat count is a Aircall billing line. You add seats there as the sales team grows; 3CX doesn't change. The economics keep working as long as the non-sales users are on 3CX and the sales-specific users are on Aircall. The threshold where it stops making sense to split is roughly 80% of users on Aircall — at which point you might as well consolidate.
