Aircall vs JustCall: A Comprehensive Comparison

Choosing between Aircall and JustCall for your business phone system often comes down to five questions:

• Do you need a polished, integration-rich phone system for established teams, or an affordable platform that bundles more features at lower price points?

• Is call quality non-negotiable, or can you tolerate occasional hiccups in exchange for cost savings?

• Do you need AI coaching during live calls, or is post-call analysis sufficient?

• Are you primarily running inbound support, outbound sales, or both?

• How important is knowing who to call and when to call them before you ever pick up the phone?

In short, here's what we recommend:

Aircall is the choice for mid-market teams that value a clean interface, strong CRM integrations, and reliable call quality. Founded in 2014 and serving 22,000+ companies, Aircall has built a mature cloud phone system with 200+ integrations, AI-powered call summaries and coaching through AI Assist Pro, and an AI Voice Agent for 24/7 inbound coverage. The trade-off is price: plans start at $30/user/month with a 3-user minimum, and many features require paid add-ons that push costs higher.

JustCall appeals to budget-conscious sales and support teams that want more features per dollar. At $29/user/month with unlimited minutes (outbound and inbound) on the base plan, JustCall includes a sales dialer, SMS workflows, AI transcription, and 100+ integrations. The platform has handled one billion conversations and counting. However, users consistently report call quality issues and mobile app bugs that weaken the value proposition.

Both platforms solve the same core problem: getting your team on the phone with customers. Neither solves the problem that comes before the call: knowing which prospects to prioritize, what signals indicate buying readiness, and how to build the right contact list. That's where ZoomInfo fits in.

ZoomInfo is an all-in-one AI GTM Platform built on three pillars that transform how revenue teams operate.

The first pillar is data. ZoomInfo maintains a foundation of 500M contacts, 100M companies, 120M direct dials with up to 95% accuracy, and 200M+ verified business emails. This isn't static information sitting in a database. It's continuously refreshed through proprietary collection methods, contributor networks, and machine learning validation.

The second pillar is the GTM Context Graph, which processes 1.5B+ data points daily. It combines ZoomInfo's data with your CRM records, conversation transcripts, and behavioral signals to surface buying intent, map decision-making committees, and identify which accounts are actively researching solutions like yours. The result: your team knows not just who to call, but when to call them and what to say.

The third pillar is universal access. Sellers work from the GTM Workspace, a unified interface for prospecting, account research, and outreach. Marketers and RevOps teams build plays in GTM Studio. And for teams that want ZoomInfo intelligence flowing directly into their existing tools, the Enterprise API and ZoomInfo MCP pipe verified contacts and intent signals into Aircall, JustCall, or any system in your stack.

The impact is measurable. Seismic reported that reps using ZoomInfo's AI-powered prospecting insights were 54% more productive and saved an average of 11.5 hours per week. That's time reclaimed from manual research and redirected toward actual selling conversations.

If you want your sales team calling the right people at the right time, see how ZoomInfo works.

Aircall vs. JustCall vs. ZoomInfo at a glance

Pricing reveals different strategies

Aircall and JustCall look nearly identical on base pricing. The real differences emerge when you dig into what's included.

Aircall's $30/user/month Essentials plan includes one phone number, unlimited domestic calling, basic IVR, and call recording.

But AI transcription and call summaries cost an extra $9/user/month. Live coaching through AI Assist Pro adds $49/user/month. Power Dialer requires upgrading to the Professional plan at $50/user/month. Analytics+ costs another $15/user/month. A sales team that wants transcription, coaching, and a dialer is looking at $99/user/month before additional phone numbers ($6/number/month) or international call charges.

JustCall's $29/user/month Team plan includes unlimited minutes, AI transcription, and 500 SMS segments.

That's a real difference.

AI transcription alone, which Aircall charges $9 extra for, comes standard. To match Aircall's Professional tier, JustCall's Pro plan at $49/user/month adds more SMS segments and additional features. The Sales Dialer with predictive capabilities requires custom pricing on the SalesPro plan.

Source: JustCall

Both platforms charge separately for AI Voice Agents. Aircall offers 50 free minutes per month with additional minutes starting at $0.19/minute in bundles. JustCall provides 50 free trial minutes with pay-as-you-go at $0.99/minute. For teams using AI voice agents at volume, Aircall costs far less per minute.

The hidden cost both platforms share: neither tells you who to call. Your team can have unlimited minutes and the best dialer available, but if they're working from a stale contact list or dialing unverified numbers, most of those minutes go to waste. Reps burn through bad numbers, reach gatekeepers instead of decision-makers, and spend hours researching accounts that aren't even in-market.

That's why teams pair these phone systems with ZoomInfo, where 120M direct dials and buyer intent signals help reps connect with the right people instead of burning through bad numbers.

Call quality separates the two more than features do

Both Aircall and JustCall are cloud-based VoIP systems that depend on internet connectivity. User feedback, however, tells different stories about reliability.

Aircall maintains 99.95% uptime and runs on AWS infrastructure with 12 points of presence globally.

Users generally praise the call quality, though some report that quality can degrade with congestion and that international calls sometimes suffer from latency. Aircall includes a Network Diagnostics Dashboard and in-app network testing to help teams identify connection issues before they affect calls.

JustCall also claims 99.95% uptime and hosts on AWS and GCP. But call quality complaints are a persistent theme in reviews. Users report call drops and unreliable connections, particularly during peak hours. Call recordings are often cut off or missing, and reviewers have described the platform as unstable with connectivity issues.

Source: JustCall

For teams where every call matters (closing enterprise deals, handling support escalations, conducting recruitment interviews), Aircall's reliability advantage is worth the price premium. For high-volume outbound teams where a few dropped calls are an acceptable trade-off for cost savings, JustCall can work. But stress-test it before committing.

AI features take different approaches

Both platforms have invested in AI, but their implementations reflect different priorities.

Aircall's AI suite splits into two tiers. AI Assist at $9/user/month provides post-call summaries, key topic recognition, sentiment analysis, talk-to-listen ratios, and automated CRM updates. AI Assist Pro at $49/user/month adds real-time capabilities: live transcription, on-call coaching prompts, playbooks for sales methodologies like SPICED and BANT, and automated call scoring with custom scorecards.

Live coaching is where Aircall pulls ahead, giving reps guidance during the conversation rather than only after it ends. One limitation: AI Assist currently supports only English and French, with German and Spanish coming soon.

JustCall's AI Copilot covers more ground but goes less deep.

Unlimited AI transcription is included on all plans, a real cost advantage over Aircall's add-on pricing. The platform includes conversation intelligence, AI coaching, agent assist, automatic call scoring, sentiment analysis, and moment analysis. JustCall's Agent Assist provides real-time guidance through script compliance and live assist modules. The SMS Copilot analyzes message tone across five parameters before sending, a feature Aircall doesn't offer.

JustCall reports that 51% of calls go unanalyzed across call centers, positioning its AI as the fix for that blind spot.

Source: JustCall

For AI Voice Agents, both platforms offer 24/7 autonomous call handling. Aircall's AI Voice Agent supports seven languages and delivered a 23% uplift in service level for one customer. JustCall's AI Voice Agent supports 14 languages and includes an outbound AI voice agent that can call prospects back in under 60 seconds, a capability Aircall hasn't released yet.

But neither platform's AI can tell your reps which accounts are ready to buy.

ZoomInfo's GTM Context Graph processes 1.5B+ data points daily to identify buying signals, map decision-making committees, and surface the accounts where outreach is most likely to convert. ZoomInfo was named a Leader in the Forrester Wave for Intent Data Providers Q1 2025, receiving the highest possible scores across eight criteria. The GTM Workspace surfaces these insights directly to sellers through AI agents that recommend next actions, draft personalized outreach, and prioritize accounts showing active buying behavior. Chorus conversation intelligence feeds back into the GTM Context Graph, creating a loop where every customer interaction improves account intelligence.

Aircall and JustCall optimize how you make calls. ZoomInfo optimizes which calls you make.

Sales dialer capabilities favor JustCall

For outbound-heavy teams, the dialer is the feature that drives daily productivity.

Aircall offers a Power Dialer on its Professional plan and above. It sequentially dials through a contact list with automatic number addition from any webpage. It works well, but it's a single dialing mode with no predictive capabilities.

JustCall provides three dialing modes. The Power Dialer handles sequential calls, achieving 80-120 calls per hour per rep. The Dynamic Dialer distributes calls across team members from a shared list. The Predictive Dialer makes multiple simultaneous calls per agent and includes answering machine detection with 75%+ accuracy.

JustCall also includes 10-line parallel dialing, voicemail drops, and multi-channel follow-ups.

JustCall adds Number Health monitoring that tracks spam risk based on daily dials and dialing patterns, along with timezone-based calling to prevent calls outside business hours.

Source: JustCall

For outbound sales teams, JustCall's dialer variety is a clear advantage. The predictive dialer alone can increase daily call volume per rep.

What amplifies any dialer is the quality of the numbers being dialed.

ZoomInfo's database of 120M direct dials with up to 95% accuracy means reps reach decision-makers instead of front desks. Loadsmart added 50% more accounts to their pipeline by layering ZoomInfo data into their outreach workflow. Feed ZoomInfo's verified contacts into JustCall's predictive dialer or Aircall's power dialer, and connect rates improve before you touch a single platform setting.

Messaging capabilities are close, with JustCall ahead on SMS

Both platforms support multi-channel messaging, but their depth differs.

Aircall recently added WhatsApp integration that brings WhatsApp messages into the same workspace as calls and SMS. The platform includes SMS/MMS on domestic routes with 250 outbound SMS and 50 MMS per user/month for US and Canada. WhatsApp integration requires an add-on, and bulk WhatsApp messaging is not currently supported.

Aircall recently added WhatsApp integration that brings WhatsApp messages into the same workspace as calls and SMS. The platform includes SMS/MMS on domestic routes with 250 outbound SMS and 50 MMS per user/month for US and Canada. WhatsApp integration requires an add-on, and bulk WhatsApp messaging is not currently supported.

JustCall includes 500 SMS segments on the Team plan and scales up on higher tiers. The platform supports bulk SMS campaigns, SMS automation workflows, and two-way texting from the same number used for calls. JustCall is an official Meta Tech Provider, which provides direct WhatsApp Business API access without third-party intermediaries.

JustCall's SMS Copilot analyzes message tone before sending, helping reps avoid messages that might come across as too aggressive or too passive. For teams running SMS-heavy outreach campaigns, JustCall's higher SMS limits and workflow automation provide more flexibility without add-on costs.

The messaging gap neither platform closes: knowing which contacts prefer SMS over calls, which accounts have gone dark and need re-engagement, and which prospects are actively researching solutions. ZoomInfo's intent signals and engagement tracking surface these patterns, helping teams choose the right channel for each contact based on behavior rather than guesswork.

Integration ecosystems reflect platform maturity

The value of a phone system multiplies when it connects seamlessly to your existing tools.

Aircall leads with 200+ integrations spanning CRMs, helpdesks, e-commerce platforms, and productivity tools. The platform was named HubSpot's 2025 Partner of the Year for telephony, reflecting deep integration with one of the most popular CRM platforms. Salesforce, Zendesk, Intercom, Shopify, and Slack integrations are all native. Aircall's open API allows custom integrations for teams with specific requirements.

JustCall offers 100+ integrations with a focus on speed. The platform claims 75% faster CRM syncs compared to competitors, reducing the lag between call completion and CRM record updates. Native integrations cover HubSpot, Salesforce, Pipedrive, Zoho, Freshdesk, and other major platforms. JustCall also provides Zapier connectivity for teams that need to connect tools outside the native integration library.

Both platforms integrate with ZoomInfo, but the depth of that integration matters.

ZoomInfo maintains 120+ marketplace integrations that go beyond simple data syncing. The Enterprise API enables programmatic access to ZoomInfo's contact database, intent signals, and company intelligence for custom workflows. The ZoomInfo MCP pipes verified contacts and buying signals directly into your existing tools, including Aircall and JustCall, so reps work from accurate data without switching applications.

The integration advantage compounds over time. When ZoomInfo data flows into your CRM, your phone system pulls from that enriched data, and conversation outcomes feed back into ZoomInfo's intelligence layer, you create a closed loop where every interaction improves future targeting.

Support and onboarding differ significantly

Implementation support and ongoing assistance can make or break a platform rollout.

Aircall provides 24/5 chat support on the Essentials plan, with email support available across all tiers. Phone support is reserved for Custom plan customers. The platform includes a comprehensive help center with setup guides, troubleshooting articles, and video tutorials. Onboarding assistance is available, though dedicated onboarding managers are typically reserved for larger deployments.

JustCall offers 24/7 support via chat and email on all plans, providing broader coverage than Aircall's weekday-only chat. However, phone support is not available on standard plans. JustCall's help center covers setup, integrations, and feature guides. The platform provides onboarding calls for new customers, though the depth of onboarding support varies by plan tier.

User reviews paint a mixed picture for both platforms. Aircall users generally praise support responsiveness but note that complex issues sometimes require escalation. JustCall users report inconsistent support quality, with some praising quick resolutions and others describing slow response times for technical issues.

ZoomInfo provides dedicated customer success managers for enterprise accounts, along with implementation support that includes data mapping, integration configuration, and workflow design. The ZoomInfo Community offers peer support and best practice sharing. For teams that need hands-on guidance during rollout, ZoomInfo's support infrastructure is built for complex deployments.

Security and compliance are comparable

Both Aircall and JustCall meet enterprise security requirements, though their certification portfolios differ slightly.

Aircall holds SOC 2 Type II certification, demonstrating ongoing security controls rather than point-in-time compliance. The platform is GDPR compliant for European data protection, CCPA compliant for California privacy requirements, and ISO 27001 certified for information security management. All data is hosted on AWS infrastructure with encryption in transit and at rest.

JustCall maintains SOC 2 Type II certification and ISO 27001:2022 certification. The platform adds HIPAA compliance for healthcare organizations, PCI DSS v4.0 for payment card data handling, and GDPR compliance for European operations. JustCall hosts on both AWS and GCP, providing infrastructure redundancy.

For healthcare and financial services teams, JustCall's HIPAA and PCI DSS certifications may be deciding factors. For most B2B sales and support teams, both platforms meet standard compliance requirements.

ZoomInfo maintains ISO 27001, ISO 27701, and SOC 2 Type II certifications. The platform holds TRUSTe certification for privacy practices and operates as a registered data broker in compliance with state-level data broker laws. ZoomInfo's privacy program includes opt-out mechanisms and data subject access request handling for GDPR and CCPA compliance.

The right choice depends on your team's priorities, budget, and where you need the most improvement in your calling workflow.

• You need verified contacts that integrate directly with your existing phone system

The most effective revenue teams don't choose between a phone system and contact intelligence. They layer ZoomInfo's data foundation underneath their calling platform, ensuring every dial reaches a verified decision-maker at an account showing buying intent.

Seismic reps became 54% more productive with ZoomInfo's prospecting insights. Loadsmart added 50% more accounts to their pipeline. These results come from solving the problem that happens before the call: knowing exactly who to reach and when to reach them.

Frequently asked questions

What is the main difference between Aircall and JustCall?

Aircall prioritizes call quality, platform stability, and deep CRM integrations, making it ideal for mid-market teams that value reliability over cost savings. JustCall bundles more features at lower price points, including AI transcription and higher SMS limits on base plans, but users consistently report call quality issues and mobile app bugs. Aircall starts at $30/user/month with a 3-user minimum and charges extra for AI features. JustCall starts at $29/user/month with a 2-user minimum and includes AI transcription on all plans.

Is ZoomInfo an alternative to Aircall or JustCall?

No. ZoomInfo is not a phone system. It's an all-in-one AI GTM Platform that provides the contact intelligence, verified phone numbers, and buying signals that make phone systems more effective. Aircall and JustCall handle the mechanics of making and receiving calls. ZoomInfo tells your team which prospects to call, when to call them, and what signals indicate they're ready to buy. The platforms serve different functions and work best when used together. If you're evaluating phone system alternatives, see our Aircall alternatives guide for a broader comparison.

How does ZoomInfo fit with Aircall or JustCall?

ZoomInfo integrates with both Aircall and JustCall through native integrations and the ZoomInfo MCP. The integration pushes verified contacts, direct dial numbers, and account intelligence directly into your phone system and CRM. Reps can access ZoomInfo's 120M direct dials and intent signals without leaving their calling workflow. The result is higher connect rates, fewer wasted dials, and more conversations with decision-makers who are actually in-market.

Which platform is cheaper for a small sales team?

JustCall is typically cheaper for small teams. A 5-person team on JustCall's Team plan pays $145/month (annual billing) and gets unlimited minutes, AI transcription, and 500 SMS segments per user. The same team on Aircall's Essentials plan pays $150/month but needs to add $45/month for AI transcription, bringing the total to $195/month. If you need a sales dialer, JustCall includes it on higher tiers while Aircall requires upgrading to the $50/user Professional plan.

Which platform has better call quality?

Aircall has better call quality based on user reviews and infrastructure investments. Aircall maintains 99.95% uptime on AWS infrastructure with 12 global points of presence and includes network diagnostics tools to identify connection issues. JustCall also claims 99.95% uptime but user reviews consistently mention call drops, unreliable connections during peak hours, and incomplete call recordings. For teams where call quality directly impacts revenue, Aircall's reliability advantage justifies the higher price.

Which platform is better for outbound sales teams?

JustCall offers more dialing capabilities for outbound sales. The platform includes three dialing modes (Power, Dynamic, and Predictive) with 10-line parallel dialing, answering machine detection, and voicemail drops. Aircall offers only a single Power Dialer mode on its Professional plan. However, dialer capabilities matter less than the quality of contacts being dialed. Teams that pair JustCall's predictive dialer with ZoomInfo's 120M verified direct dials see the highest connect rates because they're reaching decision-makers instead of gatekeepers or disconnected numbers.
