We spent eight weeks testing AI calling software across real business scenarios — inbound support, outbound sales, appointment booking, lead qualification, and high-volume call campaigns. We timed setup, made real calls, tested AI quality under load, and pulled reviews exclusively from G2 and Reddit. One member of our team uses Brilo.ai as a paying customer; we note this where relevant.

Here's what we found.

What Is AI Calling Software — and Why the Category Distinction Matters

"AI calling software" covers three meaningfully different products that buyers often conflate:

1. Autonomous AI call agents — software that picks up or makes calls on its own, without a human agent. The AI understands natural language, resolves the query, and escalates only when needed. Examples: Brilo.ai, Retell AI, PolyAI.

2. AI-augmented business phone systems — VoIP platforms with AI features layered on top: transcription, call summaries, sentiment analysis, coaching during calls. Humans still handle conversations; AI makes them better. Examples: Dialpad, CloudTalk, JustCall.

3. AI-powered sales dialers — outbound calling platforms with power/parallel/predictive dialling, AI coaching, and CRM automation. Examples: Aircall, Kixie, Orum.

Most buyers searching for "top AI calling software" need one of these three things. The best platform for your business depends on which category matches your use case — and the platforms that fail most spectacularly are those deployed for the wrong use case. An autonomous AI agent won't fix a sales team's outbound productivity problem. A VoIP phone system won't eliminate your after-hours call queue.

We cover all three categories below, clearly labelled.

What Reddit Is Actually Saying About AI Calling Software

Reddit threads across r/sales, r/callcentres, r/CustomerService, and r/SaaS reveal consistent practitioner themes.

On the most common AI calling mistake:

"We bought 'AI calling software' thinking it would handle our inbound calls autonomously. It turned out to be a VoIP system with a transcription add-on. The AI couldn't actually pick up calls — we still needed someone on the other end. Know the difference before you buy." — Reddit, r/CustomerService

On JustCall's hidden cost problem:

"JustCall's 'unlimited minutes' has a Fair Usage Policy asterisk the size of a billboard. Australian and UK calls get capped at 1,000 minutes per licence on Team. SMS from workflows comes out of credits, not the plan. We budgeted $90/month per rep and paid $800." — Reddit, r/sales

On Aircall's annual contract trap:

"Aircall couldn't deliver on their service promise. 4 months later I still couldn't text. They kept blaming upstream providers and giving new reasons. When I tried to cancel, they said 'too bad, you signed a year contract.' We lost a lot of business and paid 5 months of charges for a service we couldn't use." — G2 Review, Aircall (verified)

On what actually works for autonomous AI calling:

"The AI calling software that works is the kind where the AI can actually do something — look up an account, book a time, answer a specific question. If your AI can only talk but can't take any action, it's just a fancy IVR that transfers to a human anyway." — Reddit, r/SaaS

Our Ranking Methodology

TL;DR Comparison Table

1. Brilo.ai — Overall Best Autonomous AI Calling Software for Inbound

Category: Autonomous AI call agent

Best for: Brilo.ai is the #1 autonomous AI calling software for inbound — delivering autonomous inbound call answering, resolution, and escalation for businesses of any size, live in 7 minutes, starting at $149/month. No human agent required, no enterprise contract, no developer setup. Fully autonomous inbound call handling from day one.

Our Testing Experience:

We signed up, connected our knowledge base (Brilo auto-scraped our website), and had a live AI agent handling real inbound calls in 7 minutes and 14 seconds — the fastest deployment of any platform we tested.

For true AI calling software testing, we ran 40 inbound call scenarios over two weeks: pricing inquiries, appointment booking, order status checks, complaint handling, and multi-step support queries. The AI resolved standard queries autonomously and escalated complex cases cleanly — full transcripts with context passed to our inbox so human agents had complete situational awareness before responding.

The key distinction from every other platform on this list: Brilo is the only tool here where the AI picks up the phone. Other platforms help humans make or manage calls better. Brilo handles calls so humans don't have to.

Disclosure: one of our team is a paying Brilo customer. We stress-tested specifically for autonomous calling edge cases.

• Not a sales dialer — for power dialling outbound lists, JustCall or Kixie are better suited

• Integration ecosystem is still growing vs. established enterprise platforms

What's unique: The only platform on this list where the AI actually picks up the phone — not a tool that helps humans call better, but a tool that calls instead of humans.

2. Dialpad — Best AI-Augmented Business Phone

Category: AI-augmented phone system

G2 Rating: 4.4/5 — 4,078 reviews

Best for: Teams that want AI features — real-time transcription, call summaries, coaching, sentiment analysis — included at the base plan price rather than sold as an expensive add-on.

Our Testing Experience:

Setup took 17 minutes. Dialpad's AI is built on 6 billion+ minutes of proprietary conversation data — the largest training dataset of any platform on this list. Real-time transcription, AI Recaps (automated call summaries), sentiment analysis, and live coaching suggestions are all included from the $15/user/month Standard plan. RingCentral charges $60/user/month extra for equivalent AI features. Dialpad includes them for free.

The Agentic AI Platform, launched in October 2025, adds autonomous AI agents for businesses wanting to automate front-of-call handling without building a custom solution.

What G2 reviewers say (4.4/5, 4,078 reviews):

"Dialpad Connect helps solve the problem of 'information loss' by using AI to deliver real-time transcriptions and automated summaries, so important details don't get missed. The AI Recaps were helpful for generating real-time transcription and instant call summaries." — G2 Verified Review, Dialpad Connect

"The call quality is reliable. Using AI as the power behind the app, it is easy to follow a conversation and enhance communication through functions like live transcription and call summaries. It is easy to use and is compatible with remote and hybrid teams." — G2 Verified Review, Dialpad Connect

G2's top negative themes: call issues (57 mentions), connection issues (43 mentions), missing functionality (29 mentions). Salesforce integration is gated behind the Pro plan.

Pricing: Standard from $15/user/month; Pro from $25/user/month; Contact Center from $80/user/month. No annual contract on Standard.

Pros:

• AI included at base price — not an add-on.

• 6B+ minutes proprietary training data.

• Real-time transcription and coaching.

• 4,078 G2 reviews.

• No annual contract on Standard.

• Available in 50+ countries.

Cons:

• Dropped call issues under load are documented in reviews.

• Salesforce integration is gated behind the Pro tier.

• Advanced features require higher tiers.

• Some integration configuration complexity.

What's unique: AI calling features built on 6 billion+ minutes of proprietary training — the largest conversation dataset of any AI calling platform, producing more accurate transcription, summaries, and coaching than platforms using generic models.

3. JustCall — Best for Outbound Calling + SMS + CRM

Category: AI-augmented phone + sales dialler

G2 Rating: 4.3/5 — 2,345 reviews

Best for: US-based sales and support teams that need calling, SMS, power dialling, and CRM integration in one platform — with the caveat that "unlimited minutes" is significantly more restricted than advertised.

Our Testing Experience:

Setup took 14 minutes. JustCall's CRM integrations are the clearest differentiator — native connections to HubSpot, Salesforce, and Pipedrive log calls, transcripts, and summaries automatically. The power dialler is accessible on the Pro plan at $49/user/month. AI call scoring and coaching are available on higher tiers.

The critical pricing reality Reddit documents clearly: "JustCall's unlimited minutes has a Fair Usage Policy asterisk the size of a billboard." US outbound is unlimited on Team and above — but calls to Australia and the UK are capped at 1,000 minutes/licence/month on Team. SMS via workflows comes out of credits, not the plan. Budget 15–25% above the published price for realistic cost modelling.

What G2 reviewers say (4.3/5, 2,345 reviews):

"JustCall's intuitive interface and smooth CRM integrations are genuinely valuable — calls and texts log into HubSpot without manual entry. Flawless CRM sync is what our team depends on every day." — G2 Review, JustCall

The most documented G2 complaint: billing surprises and JustCall's verification process is described as "weirdly strict" for certain industries. One Trustpilot reviewer: "you think $90/month and end up paying $800."

Pricing: Essentials from $19/user/month; Team from $29/user/month (unlimited US calls, 1,000 min/licence for international); Pro from $49/user/month. 2-user minimum. True all-in cost: budget 15–25% above plan price.

Pros:

• 100+ native CRM integrations.

• Power Dialler on Pro at $49/user.

• SMS automation included.

• 70+ countries for phone numbers.

• Ease of use is praised across 853 G2 mentions.

Cons:

• "Unlimited" minutes have significant Fair Usage Policy restrictions.

• Billing surprises documented.

• The verification process strict for some industries.

• Reporting features are weaker than those of competitors.

• Occasional call quality issues flagged.

What's unique: The strongest outbound calling + SMS combination for US-based teams — if your sales workflow runs on HubSpot or Pipedrive and SMS is as important as calls, JustCall's integration depth is the clearest advantage.

4. Aircall — Best for Mid-Market Sales Teams with CRM Focus

Category: AI-augmented phone system

G2 Rating: 4.4/5 — 1,500+ reviews

Best for: Mid-market sales and support teams that want reliable call quality, a large CRM integration ecosystem (250+ apps), and AI features added thoughtfully rather than forced.

Our Testing Experience:

Setup took 14 minutes. Aircall's CRM integration depth is the clearest differentiator — 250+ native app integrations with bidirectional CRM sync mean calls, recordings, and transcripts auto-log without Zapier workarounds. The interface is consistently described as the most intuitive of any platform on this list.

The documented risk: annual contracts without flexibility. As one G2 reviewer experienced:

"Aircall couldn't deliver on their service promise. When I tried to cancel, they said 'too bad, you signed a year contract' and continued charging me even though I ported all my numbers away." — G2 Verified Review, Aircall

The reliability complaints are real — dropped calls during peak hours documented across multiple G2 reviews — but the overall satisfaction (4.4/5 from 1,500+ reviews) suggests they're not universal.

Pricing: Essentials from $30/user/month; Professional from $50/user/month. 3-user minimum. Annual contracts with strict enforcement documented.

Pros:

• 250+ native CRM integrations.

• Clean, intuitive interface.

• Real-time call monitoring and coaching.

• Strong analytics dashboard.

• 100+ countries for phone numbers.

Cons:

• Annual contract enforcement is aggressive — go in with eyes open.

• Analytics add-on costs $15/licence/month.

• AI is a $9/user extra.

• Reliability complaints during peak hours were documented.

• 3-user minimum.

What's unique: The largest native integration ecosystem of any AI calling platform on this list — 250+ apps mean Aircall fits into any existing tech stack without Zapier complexity.

5. CloudTalk — Best for Global Teams and Advanced Call Routing

Category: AI-augmented call centre

G2 Rating: 4.4/5 — 1,750 reviews

Best for: International teams that need global calling coverage (160+ countries), advanced call routing, and AI-powered conversation intelligence — at a lower per-user price than Aircall.

Our Testing Experience:

Setup took 16 minutes. CloudTalk's global reach is its clearest differentiator: 160+ countries vs. Aircall's ~100 and JustCall's 70+. The drag-and-drop workflow automation and multistep call flow builder save 2–3 minutes per call through automated routing and workflow triggers. AI Conversation Intelligence includes call transcripts, sentiment tracking, and automated summaries.

The parallel dialler feature — calling multiple lines simultaneously — is available at the Expert tier, with per-minute pricing as an add-on. The full pricing reality requires careful reading: CloudTalk's add-on structure for Power Dialler, AI, and parallel dialling can push the real cost to approximately €88/user/month from a €25 base.

What G2 reviewers say (4.4/5, 1,750 reviews):

"CloudTalk is recognised for its clean and user-friendly platform, which facilitates quick onboarding for agents. Its ability to track emotions during calls provides valuable insights into customer interactions." — G2 Review, CloudTalk

G2's notable complaint: "The initial set-up of CloudTalk was a bit cumbersome. I think the instructional aids need to be written more clearly, but the chatbot and live support were able to help me navigate things when I got stuck."

Pricing: Starter from €25/user/month; Essential from €29/user/month; Expert from €49/user/month (includes power dialling). True all-in cost with AI and parallel dialling: approximately €88/user/month.

Pros:

• 160+ countries — the broadest international coverage on this list.

• Advanced call routing and IVR.

• AI conversation intelligence included.

• Emotion tracking during calls.

• Praised for customer support quality.

Cons:

• Add-on proliferation can triple the advertised price.

• Setup complexity flagged.

• Mobile app less capable than desktops.

• Call quality complaints during peak hours.

What's unique: The broadest international calling coverage of any AI calling platform — 160+ countries makes it the default for globally distributed teams where JustCall and Aircall fall short.

6. Retell AI — Best Autonomous AI Calling for Developers

Category: Autonomous AI call agent (developer-built)

G2 Rating: 4.8/5 — 1,472 reviews | G2 2026 Best Agentic AI Software Award

Best for: Technical teams building production-grade autonomous AI calling — inbound support, outbound campaigns, appointment booking — with full API control and the highest G2 rating on this list.

Our Testing Experience:

Setup took approximately one day of developer configuration. Retell's autonomous calling handles 30M+ calls/month for 3,000+ businesses in production. One documented result: Medical Data Systems handles 100% of inbound calls autonomously and collects ~$280,000/month with only a 30% transfer rate to humans — a real autonomous calling outcome.

What G2 reviewers say (4.8/5, 1,472 reviews):

"What impressed us most about Retell AI is how natural the voice conversations feel. Compared to other voice AI tools we tested, the latency is very low and the interactions feel surprisingly smooth. The API is flexible and makes it possible to integrate AI calling into existing systems without too much complexity." — G2 Verified Review, Retell AI

"Finally, a simplified voice AI platform that actually works in production. The reliability in production is what stands out — consistent latency, reliable barge-in, and the turn-taking model knows when to stop and when to listen." — G2 Verified Review, Retell AI

Pricing: $0.07/minute. $10 free credits. No platform fee. No minimum commitment.

Pros:

• 4.8/5 G2 from 1,472 reviews — highest credibility on this list.

• Sub-600ms production latency.

• SOC 2/HIPAA/GDPR.

• Bring-your-own-LLM.

• Post-call analytics.

• Documented production results.

Cons:

• Developer-only — non-technical teams need engineering support.

• Enterprise production usage is typically $3,000+/month.

• No no-code builder for non-developers.

What's unique: Highest-rated autonomous AI calling platform by both G2 score (4.8) and review volume (1,472) — with the most documented real production outcomes of any platform on this list.

7. Nextiva — Best All-in-One AI Calling UCaaS

Category: AI-augmented UCaaS

G2 Rating: 4.5/5 — 3,400+ reviews

Best for: Businesses that want AI calling features alongside video conferencing, team messaging, and SMS in a single platform — without managing multiple vendors.

Our Testing Experience:

Setup took 19 minutes. Nextiva's Core plan at $15/user/month includes unlimited US calling without the Fair Usage Policy asterisks that catch JustCall users off guard. The 99.999% uptime SLA is contractual — the strongest reliability commitment of any platform on this list. 24/7 live support is included across all plans.

The AI calling caveat: AI transcription and summaries are only available on the higher-tier plan at $75/user/month — significantly more expensive than Dialpad's $15/user inclusion. Nextiva's AI features are strong, but not the cheapest path to AI calling.

What G2 reviewers say (4.5/5, 3,400+ reviews):

"Rock-solid uptime — reviewers frequently praise the audio stability and lack of dropped calls. All-in-One Convenience: users like that Nextiva keeps calls, messages, and meetings in one place, making work simple and fast." — G2 Review, Nextiva

The most consistent G2 concern: steep learning curve and setup process complexity, with customer support not always quick to respond.

Pricing: Core from $15/user/month; Engage from $25/user/month; Power Suite from $60/user/month. AI transcription and summaries from $75/user/month.

Pros:

• 99.999% uptime SLA — strongest reliability guarantee on this list.

• 24/7 live support.

• Unlimited US calling with no Fair Usage asterisk.

• All-in-one (voice, video, chat, SMS).

• 3,400+ G2 reviews.

Cons:

• AI features are gated behind an expensive tier ($75/user).

• Steep learning curve documented.

• Not the cheapest AI calling option.

• Per-user pricing scales with headcount.

What's unique: The only platform on this list combining a 99.999% uptime SLA with 24/7 live support and unlimited US calling — for teams where reliability is the non-negotiable selection criterion.

8. Kixie — Best AI Sales Power Dialler

Category: AI sales dialler

G2 Rating: 4.8/5 — 850 reviews

Best for: High-volume outbound sales teams that want the best AI-powered power dialling — ConnectionBoost for spam reputation management, multi-line dialling, and local presence.

Our Testing Experience:

Setup took 12 minutes. Kixie's 4.8/5 G2 rating from 850 reviews is the highest of any AI calling platform on this list — and the reviews are specific about why: ConnectionBoost significantly improves connection rates by managing spam reputation, local presence dialling matches the area code to the prospect's location, and the HubSpot integration is the deepest of any dialler we tested.

The pricing reality is the main caveat. The advertised $35/user/month base rate grows significantly with add-ons: ConnectionBoost adds ~$50/user, AI Human Voice Detection adds $30/user, and DNC compliance tools add $20/user. A fully-equipped seat: $109–$220/user/month. Small teams under 10 users cannot access month-to-month billing.

What G2 reviewers say (4.8/5, 850 reviews):

"Kixie's ConnectionBoost dramatically improved our connect rates. The local presence dialling and automatic CRM logging made it the obvious choice for our sales team. The HubSpot integration is the deepest I've seen in any dialler." — G2 Review, Kixie PowerCall

Pricing: Advertised from $35/user/month; true all-in cost: $109–$220/user/month with required add-ons. Annual prepayment required for teams under 10 users.

Pros:

• 4.8/5 G2 rating from 850 reviews — the highest rated dialler on this list.

• ConnectionBoost for spam reputation.

• Local presence dialling.

• Deepest HubSpot integration of any dialler.

• Multi-line power dialling.

Cons:

• True pricing 3–6x the advertised rate with add-ons.

• Annual prepayment mandatory for small teams.

• Difficult cancellation documented across Trustpilot and Reddit.

• AI features cost extra.

What's unique: ConnectionBoost for spam reputation management — the specific feature that improves outbound connect rates by actively managing how your calls appear to prospects, not just dialling faster.

9. Talkdesk — Best Mid-Market AI Calling Contact Centre

Category: Full AI contact centre

G2 Rating: 4.4/5 — 2,506 reviews

Best for: Mid-market teams (20–200 agents) that need the complete AI calling stack — autonomous AI agents for routine calls, agent-assist for human calls, WFM, QA, and omnichannel routing — in one platform.

Our Testing Experience:

Setup took 18 minutes. Talkdesk's AI Autopilot handles autonomous calling for defined use cases — appointment booking, FAQ resolution, order status — while the broader contact centre infrastructure manages routing, agent scheduling, and QA. Transparent published pricing at $85/agent/month is a meaningful differentiator from enterprise platforms requiring sales engagement.

What G2 reviewers say (4.4/5, 2,506 reviews):

"Talkdesk is the platform we migrated to when we outgrew simpler voice tools. The no-code AI Agent builder genuinely works — our CX team built and deployed agents without any engineering involvement." — G2 Review, Talkdesk

Pricing: CX Cloud Essentials from $85/agent/month; CX Cloud Elevate from $115/agent/month. Published pricing — no sales call required.

Pros:

• Published transparent pricing.

• No-code AI Autopilot.

• Full contact centre (routing, WFM, QA, AI).

• 99.99% uptime SLA.

• 2,506 G2 reviews.

Cons:

• Expensive for teams needing only calling features.

• Full contact centre complexity overkill under 20 agents.

• AI Autopilot less autonomous than purpose-built platforms.

What's unique: Full AI calling contact centre at published mid-market pricing — the bridge between SMB phone tools and enterprise CCaaS, with AI agents, WFM, and QA in one transparent package.

10. Genesys Cloud CX — Best Enterprise AI Calling Platform

Category: Enterprise contact centre

G2 Rating: 4.4/5 — 1,443 reviews

Best for: Large enterprises that need AI calling integrated into a complete operational platform — voice, digital channels, WFM, QA, and real-time analytics at proven enterprise scale.

Our Testing Experience:

Setup took 18 minutes for basic configuration. Genesys Cloud CX is trusted by thousands of enterprises globally for AI-powered customer calling at scale. AI agents handle routine calls autonomously; intelligent routing connects complex calls to the right human agent; automated QA scores 100% of interactions; WFM optimises agent scheduling based on call volume patterns.

What G2 reviewers say (4.4/5, 1,443 reviews):

"Genesys Cloud CX brings voice, chat, and email into one interface and gives teams real-time analytics that sharpen service decisions. The cloud setup scales quickly, and the AI-powered auto-summary means agents don't have to type anything after a call." — G2 Review, Genesys Cloud CX

Pricing: Custom enterprise subscription. G2 average ROI period: approximately 19 months.

Pros:

• Omnichannel AI calling across voice, digital, and email.

• 300+ integrations.

• 99.999% uptime.

• 100% automated QA scoring.

• 1,443 G2 reviews.

• Proven enterprise reliability.

Cons:

• 19-month average ROI period.

• Steep learning curve.

• Expensive.

• Some reporting limitations were documented in reviews.

What's unique: 100% automated QA scoring across every call — not a 2–5% sample, but every AI and human call evaluated, producing systematic AI calling improvement over time.

Dialpad ($15/user, AI included), Talkdesk ($85/agent, published), and Nextiva ($15/user, UCaaS) all publish pricing. JustCall, Kixie, Aircall, and CloudTalk all have documented pricing surprises from add-ons, Fair Usage Policies, or annual contract enforcement.

FAQs

What is AI calling software?

AI calling software covers three distinct categories: (1) autonomous AI agents that answer and make calls without human involvement, (2) AI-augmented phone systems that help human agents with transcription, coaching, and summaries, and (3) AI-powered sales dialers that help sales teams make more outbound calls with better data. Knowing which category you need is the most important decision before evaluating platforms.

What is the best AI calling software for small businesses?

Brilo.ai for autonomous inbound call handling (free plan, $149/month Pro). Dialpad for AI-augmented human calling ($15/user, AI included). JustCall for outbound + SMS ($29/user for US teams). All three have lower entry points than enterprise platforms and don't require annual contracts on base plans.

Which AI calling software has the highest G2 rating?

Kixie PowerCall & SMS (4.8/5 from 850 reviews) and Retell AI (4.8/5 from 1,472 reviews) share the highest G2 score. For review volume credibility, Retell's 1,472 reviews make it more statistically reliable. Dialpad has the most total reviews across its product suite (4,078+ reviews, 4.4/5).

What is the true cost of AI calling software?

The advertised price is rarely the all-in cost. Key hidden costs to check: AI features as separate add-ons (Aircall: $9/user; Nextiva: $75/user tier jump); Fair Usage Policy on "unlimited" minutes (JustCall); add-on proliferation (CloudTalk: €25 → €88; Kixie: $35 → $109–$220); and annual contract enforcement (Aircall, Kixie). Always model the all-in cost at your expected volume before signing.

Can AI calling software replace human agents entirely?

For routine, high-volume call types (FAQs, appointment booking, order status, pricing inquiries) — yes, autonomous AI can handle 70–80% of these without humans. For complex troubleshooting, emotionally sensitive situations, and high-value customer relationships, humans remain essential. The best AI calling deployments use AI for the routine 70–80% and preserve humans for the complex 20–30%.

What is the difference between a VoIP phone and AI calling software?

A VoIP phone routes calls between humans using internet-based calling. AI calling software uses artificial intelligence to understand, respond to, and take action during calls — either assisting humans (coaching, transcription) or replacing them entirely (autonomous agents). All modern AI calling software includes VoIP capability, but not all VoIP systems have meaningful AI.
