The best AI call centre software does not answer every call with a robot. It answers the simple calls with a robot, routes the hard calls to the right human faster, and gives that human a summary, a suggested next step, and a record that writes itself. The result is shorter queues, fewer repeat calls, and agents who spend their time on conversations that actually need a person.
This guide groups 13 tools by the call centre job each one does best: inbound contact centres, outbound dialling and sales, AI voice agents and chatbots, quality assurance and analytics, and workforce management and integrations. Prices are October 2026 figures in US dollars. Where a vendor hides pricing or sources disagreed, the guide says check checkout rather than guessing.

Inbound contact centres: answer, route, resolve
Inbound is the core job. Calls arrive in waves, customers repeat themselves across channels, and the difference between a good centre and a bad one is usually routing plus context. If you collect customer requests through your own site first, see our best AI form builders guide for the form side of the intake.
1. Genesys Cloud CX
Genesys Cloud CX is the enterprise standard for inbound at scale. It covers voice, web messaging, email, SMS, in app messaging, WhatsApp and social in one routing engine, and its AI Studio builds virtual agents that handle routine contacts and hand over to humans with full context.
Pricing: CX 1 costs $75, CX 2 costs $115, CX 3 costs $155 and CX 4 costs $240 per user per month billed annually. Named, concurrent and hourly licence options exist, and AI virtual agent use is metered in tokens on top of the seat price.
Best for: Large and global teams that need complex routing, many channels, and workforce tools in the same platform.
Watch out for: Cost and complexity. The entry tier is voice only, so omnichannel teams start at CX 2 or higher. Small teams will find the platform heavier than they need.
Try it at: genesys.com
2. Talkdesk
Talkdesk is the industry tuned option. It ships prebuilt clouds for healthcare, financial services, retail and other regulated sectors, with the compliance controls and workflows those industries need, plus AI Copilot for agent assist, call summaries and automated quality checks.
Pricing: Digital Essentials costs $85, Voice Essentials costs $105, Elite costs $165 and Industry Clouds cost $225 per user per month.
Best for: Mid market and enterprise teams in regulated industries, and teams that want a modern interface with a faster deployment than the older enterprise suites.
Try it at: talkdesk.com
3. Five9
Five9 is built for large teams that run shifts. Its concurrent seat licensing means you pay for agents on the floor at once, not for every named employee, which suits centres with part time staff and rotating shifts. Its Genius AI layer adds summaries, agent assist and voice AI agents, and its outbound dialer suite is among the strongest in this guide.
Pricing: Digital costs $119 and Core costs $159 per concurrent seat per month, with a 50 seat minimum. Higher bundles are quote only, and AI minutes beyond the included allowance are billed per minute.
Best for: Large centres, especially in regulated industries, that need compliance grade uptime, strong outbound dialling, and concurrent licensing.
Watch out for: The 50 seat floor rules out small teams entirely, and implementation typically takes weeks of professional services. Budget for the seat price plus add ons, not the seat price alone.
Try it at: five9.com
4. Aircall
Aircall is the small team inbound option. It sets up in days, not months, with IVR menus, call queues, shared numbers and live monitoring, plus deep CRM integrations with HubSpot, Salesforce and Zendesk. Its AI Voice Agent answers simple calls and its AI features add summaries and call insights.
Pricing: Essentials costs $30 and Professional costs $50 per licence per month billed annually, with a 3 licence minimum. AI features are an add on from around $9 per licence per month, and the AI Voice Agent includes 50 minutes a month before a per minute charge applies.
Best for: Small teams that need a proper call centre without an enterprise contract, and support teams that live inside their CRM.
Watch out for: Outbound dialling power is limited compared with CloudTalk or Kixie, and minute allowances can surprise international teams. Aircall wins on inbound simplicity, not on dialler depth.
Try it at: aircall.io
Outbound dialling and sales: connect faster, talk more
Outbound lives or dies on connect rates. The dialler, the number reputation, the CRM sync and the call recording matter more than any single AI feature. For the list building side of outbound, see our best AI sales prospecting tools guide.
5. JustCall
JustCall is the all rounder for small outbound and support teams. It combines cloud calling, SMS and WhatsApp workflows, power and predictive diallers, call recording, and an AI Voice Agent add on, with CRM integrations from the entry plan. Solo operators and small teams get a full stack without buying three tools.
Pricing: Team costs $29, Pro costs $49 and Pro Plus costs $89 per user per month billed annually, with a 2 licence minimum. Unlimited calling applies to US outbound under a fair usage policy, while other regions get capped minutes per licence.
Best for: Growing sales and support teams that want calling plus SMS automation in one place, and teams that run heavy WhatsApp workflows.
Watch out for: Dialler performance sits a tier below dedicated outbound platforms, and SMS sent through workflows draws down a credits balance rather than being included. Check the minute caps for your region before committing.
Try it at: justcall.io
6. CloudTalk
CloudTalk is the global outbound option. It offers numbers in more than 160 countries, preview, power, parallel and smart diallers, real time analytics, and a growing AI layer that includes an AI Voice Agent and an AI Receptionist. Its Salesforce integration sits on the Expert tier.
Pricing: Starter costs $25, Essential costs $29 and Expert costs $49 per user per month billed annually. The AI Receptionist is a separate add on from $99 a month for 200 minutes, and advanced diallers cost extra on lower tiers.
Best for: International sales and support teams that need local numbers worldwide, and mid size teams scaling outbound across several countries.
Watch out for: The headline price buys the phone system, not the full dialler and AI stack. Teams that need the smart dialler and Salesforce sync should budget for Expert plus add ons.
Try it at: cloudtalk.io
7. Kixie
Kixie is the pure outbound dialler. It is built for sales teams that live on the phone: a Salesforce native power dialler, local presence dialling, automated voicemail drops, real time coaching, and AI insights on every call. It connects to HubSpot and other CRMs, but its heart is high volume outbound.
Pricing: Plans are reported from around $35 per user per month billed annually, with higher tiers for larger teams. Kixie does not publish a full price list, so check checkout for the current tiers.
Best for: Outbound heavy SDR teams that need to maximise live conversations per hour, and teams already running Salesforce.
Watch out for: It is a dialler first, not a full contact centre. Inbound routing, omnichannel queues and workforce tools are thinner than on Genesys or Talkdesk, so pair it with a support platform if you run both sides.

AI voice agents and chatbots: let AI take the simple calls
Voice agents answer calls, qualify callers, book appointments and take messages around the clock. The three tools here are the smaller, newer names in this guide, and they are the ones most worth testing, because they move faster and price by the minute rather than by the seat.
8. Vapi
Vapi is the developer platform for voice agents. You choose the transcription engine, the language model and the voice, and Vapi provides the orchestration, the phone numbers and the call handling. That freedom is the point: teams can tune latency, cost and voice quality precisely, and run many agents at once.
Pricing: There is no platform fee on the entry tier, with $5 of credits to start. Vapi charges $0.05 per minute for hosting, plus provider costs passed through at cost: roughly $0.01 for transcription, $0.01 to $0.05 for the model and $0.015 to $0.024 for the voice. A typical call lands between $0.08 and $0.14 per minute before carrier charges, and HIPAA compliance is a $2,000 a month add on.
Best for: Developer teams that want full control over the voice stack, and agencies building agents for many clients.
Watch out for: Someone has to build it. The agent, its prompt, its phone number and its CRM links are all yours to assemble, and the bill has several lines that move with your model choice. Teams with no developer should start with Retell AI instead, and teams that want to build can see our best AI tools for learning to code guide for the coding path.
Try it at: vapi.ai
9. Bland AI
Bland AI is the outbound voice agent specialist. It runs high volume outbound campaigns with a single flat per minute rate that covers the model, transcription and voice, which makes forecasting simple. It handles appointment booking, lead qualification and follow up calls, and its enterprise tier adds warm transfers and guardrails.
Pricing: Start has no platform fee and costs $0.14 per minute. Build costs $299 a month and drops the rate to $0.12 per minute, with 50 concurrent calls included. Telephony is billed separately, and transfer minutes cost extra on Start.
Best for: Teams running high volume outbound voice campaigns that want one predictable rate rather than a component bill.
Watch out for: At high volume Bland is the most expensive of the three voice platforms here, and its model wiring is less flexible than Vapi. The $299 tier only beats Start above roughly 15,000 minutes a month, so do the maths on your real volume first.
Try it at: bland.ai
10. Retell AI
Retell AI is the easiest managed voice agent to deploy. It prices transparently by component, ships a visual builder and phone numbers, and handles inbound answering, appointment booking and call transfers with low latency voices. Agencies like it because clients can be live in days.
Pricing: No platform fee, with $10 of credits to start. Per minute rates run from $0.07 to $0.31 depending on model, voice and add ons. A typical setup costs about $0.11 per minute: $0.055 for voice infrastructure, $0.015 for the voice, $0.04 for a mid tier model, plus $0.015 for Retell telephony.
Best for: Small businesses and agencies that want a finished inbound agent without engineering, and teams that want transparent per minute pricing.
Watch out for: Premium voices and top models push the rate toward the top of the range, and knowledge base, guardrail and privacy add ons are billed per minute each. Price your real configuration, not the cheapest one.

Quality assurance and analytics: score every call, coach every agent
Human QA teams sample 2 to 5 percent of calls. AI QA scores all of them. That gap is the whole case for this section: every missed coaching moment, every compliance risk and every repeat contact pattern becomes visible.
11. Observe.AI
Observe.AI scores 100 percent of voice and chat interactions automatically, flags compliance risks, and turns coaching insights into agent scorecards. Its VoiceAI agents also automate end to end calls, and its platform is built for enterprise centres that need evidence, not anecdotes, about quality.
Pricing: Custom only, sold as an annual contract. One module is listed at around $69 per agent per month on a marketplace listing, and the full platform is reported in the $60,000 to $180,000 a year range for enterprise deployments. Check checkout and expect a sales conversation.
Best for: Enterprise centres that need automated QA across every interaction, and regulated teams where a missed compliance phrase carries real risk.
Watch out for: Cost and contract size. Observe.AI is priced for enterprises, not for a ten seat team.
Try it at: observe.ai
12. Cresta
Cresta guides agents while the call is still live. It listens, surfaces the right knowledge article, suggests the next best action, and flags risky language before it becomes a complaint. After the call it writes the summary and scores the interaction, so coaching is based on live behaviour rather than memory.
Pricing: Custom only, sold as an annual contract. Cresta does not publish a price list, so check checkout and expect pricing tied to seat count and call volume.
Best for: Teams where agent guidance matters more than post call scoring, and centres selling complex products where the right answer is hard to remember under pressure. Teams that also publish help content can see our best AI tools for content creators guide.
Try it at: cresta.com
Workforce management and integrations: run the whole operation
The last job is the operation itself: forecasting call volume, scheduling agents, tracking performance, and connecting the contact centre to the CRM, the helpdesk and the rest of the business.
13. NICE CXone
NICE CXone is the full suite. It combines omnichannel routing, AI agents, quality management, workforce management, performance management and more than 200 integrations in one platform, with Copilot for agents, supervisors and leaders on the top tier. Small teams often start on it for one feature and grow into the rest.
Pricing: Omnichannel costs $110, Essential costs $135, Core costs $169, Complete costs $209 and Ultimate costs $249 per agent per month, plus $0.25 per session on Ultimate. Quality management starts at Essential, performance management at Core, and Copilot sits in Ultimate only. Small teams should also read our best AI tools for small business guide before committing to an enterprise suite.
Best for: Large centres that want one vendor for routing, QA, workforce and AI, and teams planning to add AI agents alongside human agents.
Watch out for: The suite price is a starting point, not a total. Session fees on Ultimate, consumption billed copilots and implementation services all add up, and the platform needs dedicated administrators to run well.

A realistic small team stack costs $30 to $90 per agent per month: Aircall or JustCall for the phones, plus a Retell AI agent for after hours calls. A mid size centre runs $85 to $170 per agent per month on Talkdesk or Genesys. An enterprise suite with QA and workforce tools runs $110 to $250 per agent per month before usage charges.
How to choose
Start from the bottleneck, not from the tool list. If queues are long and routing is the problem, start with Genesys, Talkdesk or NICE CXone. If nobody answers after hours, start with a Retell AI agent before hiring night staff. If agents give inconsistent answers, start with Cresta or Observe.AI and fix guidance and coaching first. If outbound connect rates are low, start with Kixie or CloudTalk and fix the dialler and the number reputation.
Second, count the real cost per handled contact, not the seat price. Seat licences, per minute AI charges, session fees, implementation services and add ons all land on the same invoice. Run one real month of volume through your shortlist and record the true cost, the average handle time and the first contact resolution rate.
Third, protect the customer experience while you automate. An AI agent that books appointments badly costs more trust than it saves in wages. Start voice agents on one narrow job, such as after hours message taking or appointment booking, measure containment and escalation rates, and only widen the scope when the numbers support it. Freelance operators running a small support line should also read our best AI tools for freelance writers guide for the solo business side of the operation.
Frequently asked questions
Can an AI voice agent replace my support team?
No, not for most businesses. Voice agents handle routine, predictable calls well: bookings, order status, opening hours, message taking. They struggle with angry customers, complex complaints and anything that needs judgment. The winning setup is AI for the simple calls and humans for the rest, with a clean handover between them.
How much does AI call centre software really cost per month?
For a small team, $30 to $90 per agent per month plus any per minute voice agent charges. For a mid size centre, $85 to $170 per agent per month. For an enterprise suite with QA and workforce tools, $110 to $250 per agent per month before usage. Always budget 20 to 30 percent above the headline seat price for add ons and usage.
Do I need a full contact centre platform, or will a phone system do?
A phone system is enough up to about five agents handling simple inbound calls. Once you need queues, skills based routing, omnichannel history, QA scoring and workforce scheduling, a contact centre platform pays for itself in fewer missed calls and less supervisor time.
Is AI call scoring accurate enough to replace human QA?
For compliance checks and common quality criteria, yes, and it covers 100 percent of calls instead of a small sample. For nuanced coaching, human reviewers still add value. Most teams use AI scoring for everything and human review for the edge cases and the coaching conversations.
Will customers accept talking to an AI voice agent?
For short, transactional calls, yes, especially outside business hours when the alternative is voicemail. For complaints and complex problems, customers still want a human, and forcing an AI agent on those calls damages trust. Offer a clear path to a human at every step.
Which single tool should a new call centre start with?
Aircall for a small inbound team, JustCall for a team that mixes sales and support, and Talkdesk for a team that expects to grow past 20 agents. Add a Retell AI agent for after hours coverage before adding headcount.
Conclusion
The best AI call centre software removes the slow parts of running a support operation: the queue, the repeated questions, the missing call notes, the unreviewed calls and the guesswork in scheduling. Genesys, Talkdesk and Five9 run large inbound floors. Aircall and JustCall give small teams a proper centre without an enterprise contract. CloudTalk and Kixie connect outbound teams faster. Vapi, Bland AI and Retell AI answer the calls your team cannot. Observe.AI and Cresta turn every call into coaching. NICE CXone holds the whole operation in one suite.
Start with the bottleneck. If callers wait too long, fix routing. If nobody answers at night, add a voice agent. If quality is invisible, add AI scoring. Test with real call volume, measure handle time and first contact resolution, and keep only the tools that earn their fee.
