TL;DR
- Quo Business is the lower-cost alternative for a small team making manual or CRM click-to-call calls while sharing callbacks and messages. It costs $23/user/month annually or $33 monthly; HubSpot and Salesforce integrations are on Business and Scale.
- CloudTalk Essential plus Power Dialer fits a one- or two-person team needing campaign calling and a standard CRM integration. Salesforce moves the purchase to Expert, with a three-licence minimum.
- JustCall Pro qualifies for power dialing and Salesforce, with a two-licence minimum. Its ordinary phone and Sales Dialer numbers are separate; preserve callback and SMS routing when choosing where each number lives.
- PhoneBurner is a specialist power dialer. It costs more, but may justify that premium for sustained calling sessions. Premium is the relevant tier for answering callbacks in the app.
- Aircall remains a sensible choice when its routing and integration already work. A cheaper licence is worthwhile only if the migration preserves useful calls and follow-up.
What are you replacing
Start with the reason for leaving Aircall. A one-person team paying for unused seats needs a different replacement from three SDRs whose dialing workflow is too slow. A team selling internationally has a different cost problem again: its destinations and number types may matter more than the licence.
Aircall's Professional plan is $50/licence/month on annual billing, with three licences minimum. That is the relevant baseline for its Power Dialer and Salesforce CTI. Essentials is a lower phone-system tier, but does not supply those capabilities. One number is included and extra numbers are $6/month. Aircall pricing.
Do not replace a shared phone system with an outbound tool and discover later that callbacks have nowhere useful to go. Likewise, a cheaper click-to-call app is a good alternative for modest call volume, but a different workflow from a power dialer working automatically through a list.
This shortlist therefore includes both phone-system replacements and a specialist dialer. It is scoped to small human sales teams, rather than autonomous voice agents or enterprise contact centres.
Small-team comparison
Prices below are US-dollar base prices checked on 30 September 2026. Annual figures are monthly allocations of annual commitments. Calling destinations, extra numbers, messages and implementation can add costs.
| Alternative | Practical qualifying purchase | Seat boundary | CRM scope to budget | Callback model |
|---|---|---|---|---|
| Quo | Business $23/user/month annual or $33 monthly | Per-user purchase suitable for an individual or small team | HubSpot and Salesforce on Business/Scale | Shared phone workflow, transfers, ring order and messages |
| CloudTalk | Essential $29 annual or $39 monthly; Power Dialer $15/user/month annual add-on | Essential minimum one; Expert minimum three | Standard integrations on Essential; Salesforce on Expert $49 annual/$69 monthly, Power Dialer included | Phone-system routing and ported numbers |
| JustCall | Pro $49 annual or $69 monthly | Minimum two licences | Salesforce CTI and power dialing qualify on Pro | Ordinary JustCall and Sales Dialer have separate numbers/routing |
| PhoneBurner | Standard $140 annual/$165 monthly; Professional $165/$195; Premium $183/$215 | Individual and team purchase | Native Salesforce app; browser softphone and Open API on Professional+ | Premium includes number, inbound routing and in-app callback answers |

The four alternatives
1. Quo Business
Best for: A founder or small team making considered individual calls and needing a shared phone and message history.
Quo, formerly OpenPhone, prices Business at $23/user/month annually or $33 monthly. It includes one new or ported number per user, transfers, custom ring orders, phone menus, automatic recording and AI call summaries. The included US/Canada calling and messaging are subject to its fair-use terms; international destinations are separately priced. Current plans.
Business and Scale support its CRM integrations. Salesforce contact sync is one-way from Salesforce into Quo, with call, text and voicemail activity logged back. HubSpot contact sync is described as bidirectional. These are distinct connector behaviours, rather than a universal two-way-sync promise. Click-to-call is a practical fit for a rep who prepares each outreach individually. Salesforce integration, HubSpot integration.
Quo advertises free number porting with a managed process and estimated carrier-dependent timelines. That supports retaining a published business number without automatically paying an additional porting fee to Quo. Porting.
Where it falls short: This recommendation is for shared calling and CRM click-to-call. It does not price an automatic outbound campaign dialer. A team spending hours daily progressing through lists should compare the specialist workflows below.
Verdict: The strongest budget alternative here when the small team's real need is a coherent phone workflow and callbacks, rather than maximum dialing throughput.
2. CloudTalk
Best for: A small campaign-calling team that wants a phone system, CRM context and the ability to add power dialing.
Essential starts with one licence, making it useful below Aircall's floor. Its standard CRM integration and API scope make it a better comparison than a cheap phone-only plan. Power Dialer is a $15/user/month annual add-on; Expert includes it. The sequential dialer provides session controls, voicemail drop, call outcomes and contact context. Feature and add-on matrix.
The important gate is Salesforce. Expert is $49/user/month annually or $69 monthly, with three licences minimum. A two-person Salesforce team therefore buys at least three Expert seats. That erases most of the headline saving versus Aircall Professional. For HubSpot and other standard supported CRMs, Essential offers the lower entry route. Current USD plan scope.
CloudTalk supports number porting; its stated timeline is typically around 15 business days, depending on carrier and number type, with country-specific costs. Treat that as migration planning information rather than a guaranteed cutover date. Porting basis.
Where it falls short: Add-ons and CRM gates change the cheap-seat arithmetic. Parallel dialing and conversation intelligence are separate additions, and country-specific calling bundles still matter.
Verdict: A strong small-team power-dialing option for standard CRM use. For Salesforce, compare the three-seat Expert purchase with Aircall's working configuration rather than comparing Essential's sticker price.
3. JustCall Pro
Best for: Two or more callers needing campaign calling, Salesforce access and a broader calling-and-messaging workflow.
Pro is $49/user/month annually or $69 monthly, with two licences minimum. Power Dialer is available on Pro, Pro Plus, Business and SalesPro; Dynamic and Predictive modes belong to the SalesPro offer. A full-feature trial therefore does not establish what the cheaper paid tier retains. Licence requirements, dialer scope, prices and bundles.
Its current Pro card includes Salesforce CTI. The newer regional bundle documentation gives US/Canada Pro unlimited qualifying inbound and outbound minutes, but credits still pay for exclusions such as Sales Dialer inbound calls, forwarding and selected automated services. It is a base subscription with defined calling coverage, not unlimited every-kind-of-usage. Plan matrix, new regional plans, billing exclusions.
Number assignment is its material distinction. A number cannot be active in ordinary JustCall and Sales Dialer simultaneously. Moving it to Sales Dialer removes it from JustCall and its SMS capabilities there. Keep separate numbers when both workflows are needed. Number rules.
A current account-level setting keeps ordinary JustCall reachable while reps work Sales Dialer campaigns and routes calls to available reps. It does not change direct inbound handling on Sales Dialer numbers or automatically update campaign retry logic from an inbound outcome. Inbound continuity setting.
Where it falls short: Its two-seat floor still affects solo callers, and separate number systems add a routing decision. A low base price is less useful if a prospect returns a call on a line the team does not monitor.
Verdict: The clearest two-person power-dialer/Salesforce alternative here. Design the ordinary phone and campaign numbers together so the saving does not fragment customer conversations.
4. PhoneBurner
Best for: An individual or small team whose primary job is sustained power-dialing sessions.
PhoneBurner concentrates on sequential dialing, dispositions, voicemail, follow-up and session management. Standard is $140/user/month annually or $165 monthly. Professional is $165/$195, adding browser softphone, monitoring/coaching and Open API. Premium is $183/$215, adding a PhoneBurner number, custom inbound routing and callback answers in the app. A free team admin account is included. Current pricing.
Its Salesforce app installs without an app charge and supports dialing selected records with activity, notes and outcomes logged in Salesforce. The underlying Salesforce and PhoneBurner accounts remain separate purchases. Salesforce integration.
For callbacks, its inbound product can forward to another owned number or let the rep pause a session, answer and resume. That makes Premium the useful same-app comparison when replacing Aircall's inbound workflow. Standard's lower price is more relevant when the business retains its existing inbound phone arrangement. Inbound workflow.
Where it falls short: It is substantially more expensive than the small-team phone systems here. Browser calling and in-app callbacks also sit above Standard. Do not justify that premium with an unsupported promise of higher connect rates.
Verdict: Buy it for the dedicated rep workflow and measurable time saved in sessions. It is a capability alternative to Aircall, rather than the default cost-cutting replacement.
One two and three caller costs
This table applies seat minimums to annual base prices. It excludes numbers not already included, calling extras, tax, CRM licences and implementation.
| Purchase | One caller | Two callers | Three callers |
|---|---|---|---|
| Aircall Professional, minimum three | $150/month allocation | $150 | $150 |
| Quo Business | $23 | $46 | $69 |
| CloudTalk Essential + annual Power Dialer | $44 | $88 | $132 |
| CloudTalk Expert for Salesforce, minimum three | $147 | $147 | $147 |
| JustCall Pro, minimum two | $98 | $98 | $147 |
| PhoneBurner Premium for in-app callbacks | $183 | $366 | $549 |
For two users, annual licence allocations are $552 for Quo Business, $1,056 for CloudTalk Essential plus Power Dialer, $1,176 for JustCall Pro, $1,800 for Aircall Professional and $4,392 for PhoneBurner Premium. The workload differs across those purchases, especially Quo's individual calling versus campaign dialers.
Monthly cancellation flexibility has a price. Two Quo Business seats are $66/month, versus $46 as an annual allocation. Two JustCall Pro seats are $138/month, versus $98 annually. Two PhoneBurner Premium seats are $430/month, versus $366 annually. CloudTalk monthly base prices are published, but an annual add-on price should not be silently treated as its monthly tariff.
A two-rep migration example
Assume two reps use a standard supported CRM, each making 60 attempts per day for 20 days: 2,400 monthly attempts. At an illustrative 8% connection rate, that is 192 conversations. No product is assumed to change that connection rate.
Aircall Professional's three-seat purchase is $150 in annual monthly allocation. Two dedicated numbers, using its included one plus one additional $6 number, bring the known subtotal to $156. On the licence-only bases, Quo Business is $46, CloudTalk Essential plus Power Dialer $88 and JustCall Pro $98. PhoneBurner Premium is $366. Their number and usage inclusions differ, so these are decision inputs rather than identical all-in totals.
If migration takes an assumed six staff hours at $50/hour, setup costs $300. Quo's $110 difference from the Aircall subtotal recovers that in 2.73 months before extras. CloudTalk's $68 difference takes 4.41 months; JustCall's $58 takes 5.17 months. For Salesforce, CloudTalk Expert at $147 leaves only a $9 base difference, giving 33.33 months on that narrow saving. Such a move needs a workflow reason.
PhoneBurner Premium adds $210/month over the $156 Aircall subtotal. It needs 4.2 hours/month of useful rep time saved at $50/hour. Across 2,400 attempts, that is 6.3 seconds per attempt. That is a plausible evaluation threshold, not a vendor performance claim.
Callback loss can overwhelm small savings. If 20 callback conversations currently produce four meetings, losing ten of those conversations at the same assumed conversion costs two meetings. A $58 saving is then only $29 per lost meeting. This illustrates why inbound continuity deserves equal weight with seat price; it does not assign a monetary value to your meetings.
Keep callbacks and history usable
Move the phone workflow before removing the old one. Prepare ring groups, business hours, voicemail, forwarding and the owner for unanswered callbacks on the replacement. Route a trial call to a free rep, a busy rep and outside-hours handling so the published number has a deliberate destination in each case.
Keep the old service active through the porting cutover and preserve the required account and number details. Porting retains the number; it does not import recordings, messages or historical CRM links. Save the history the team needs before closing access.
For CRM continuity, look at an answered outbound call, a missed call, a callback and a message where supported. They should attach to the correct person and rep and preserve the next action. Quo's Salesforce and HubSpot contact sync have different directions; JustCall's phone-number split means campaign and ordinary-phone events need separate attention.
This is a focused migration check, not an exhaustive procurement round. Its purpose is to preserve customer conversations while replacing the tool.
Which alternative to buy
Choose Quo Business for lower-volume individual calling and a shared phone workflow. Choose CloudTalk Essential plus Power Dialer for small campaign teams on standard supported CRMs. Choose JustCall Pro for two callers needing power dialing and Salesforce, with deliberate number routing. Choose PhoneBurner for a dedicated dialing workflow whose time savings justify the premium.
Stay with Aircall when its phone routing and CRM setup already work and the qualifying alternative barely reduces cost. Use the signal-based outbound playbook to keep list selection, account context and follow-up aligned with the calling system.
FAQ
What is the cheapest alternative for two callers in this shortlist?
Quo Business has the lowest illustrated CRM-connected base at $46/month on annual billing. It is an individual calling and shared-phone recommendation rather than the same automatic campaign workflow as a power dialer.
Is CloudTalk always cheaper than Aircall?
No. Essential can start with one licence, but Salesforce requires Expert with three licences. Its $147 annual monthly allocation is close to Aircall Professional's $150 floor.
Can JustCall use one number for both phone and Sales Dialer?
Its current documentation says the number cannot be active in both simultaneously. Keep the appropriate ordinary-phone and campaign numbers and callback routing separate.
Which PhoneBurner tier preserves in-app callbacks?
Premium includes the number, custom inbound routing and answering callbacks in the app. Lower tiers are a different comparison where the business keeps an existing inbound arrangement.
Should number porting happen before cancelling Aircall?
Keep the old service active until the number cutover and replacement routing are working. Save needed recordings and message history separately; porting the number does not move that history.
