The 15 tools, reviewed
#1 Kavkom
Cheapest published entry price, from €10/user/month · France · kavkom.com
Cheapest published price Built-in hybrid CRM European vendor
Kavkom, operating from Paris since 2012, undercuts every other vendor in this category on headline price: €10 a user a month for the Basic Pack, with a hybrid CRM built into the platform and AI call transcription and summaries added at the Plus Pack rather than sold as separate add-ons.
- Pricing: Per user / month. Basic Pack €10/user/month (€8 with a 12-month term). Free plan: free trial.
- Best for: Small French/European sales teams on a tight budget
- Strengths: IVR with voice menus; Ring groups with time-based routing; Real-time supervision dashboard.
Where it falls short
What is not included at €10 is what makes a tool a call center rather than a phone system: the Basic Pack covers unlimited inbound calls but not unlimited outbound calling, native CRM integrations or AI transcription, the predictive dialer and automated voice agent are paid add-ons on every pack, and skill-based routing sits behind the quote-only Custom Pack.
Wrong for
A contact center that needs predictive dialing or skill-based routing out of the box.

#2 Odigo
European sovereign cloud CCaaS, four decades of heritage · France · odigo.com
European sovereign cloud 40 years of heritage European vendor
Odigo's lineage runs back to France's first audiotel service in 1986, through Prosodie-Capgemini, before Capgemini sold the CCaaS business to private-equity firm Seven2 in 2020.
- Pricing: Quote only. Essential (5-500 users), Enterprise (500-5,000+ users) and CXaaS (1,000-50,000+ users) tiers, all quoted on request. Free plan: none.
- Best for: Large enterprises that require a sovereign-cloud deployment
- Strengths: Omnichannel voice, chat, email; Agentic AI automation; Intelligent routing.
Where it falls short
None of its three tiers, segmented by user count from 5 up to 50,000-plus, publish a price; every deal is quoted.
Wrong for
A small team wanting same-day self-serve signup; every Odigo tier requires a sales conversation regardless of size.

#3 Puzzel
Nordic CCaaS pioneer since 1998, AI Co-Pilot for live agents · Norway · puzzel.com
Operating since 1998 AI Co-Pilot European vendor
Puzzel has run out of Oslo since 1998 and describes itself as one of the first vendors to build a cloud contact-centre offering, today handling 83 million conversations a month across the Nordics, UK and Netherlands.
- Pricing: Quote only. Enterprise CCaaS pricing quoted on request. Free plan: none.
- Best for: Nordic and UK organizations wanting AI assistance for live agents
- Strengths: Omnichannel workspace (voice, chat, email, SMS, video, social); Control Centre for managers; AI Agent Assist and Co-Pilot.
Where it falls short
Pricing is not published anywhere; Puzzel sells through a sales conversation only, with no self-serve signup.
Wrong for
A small team outside the Nordics/UK wanting a self-serve signup rather than a sales-led enterprise process.

#4 CloudTalk
No-code call-flow builder with published per-seat pricing from €19/month · Slovakia · cloudtalk.io
Published pricing No-code IVR builder European vendor
CloudTalk is one of the few vendors in this list that publishes a real per-seat price on every one of its tiers rather than routing a buyer to a sales call for anything beyond the cheapest plan.
- Pricing: Per user / month. Lite €19/user/month (annual, €27 monthly). Free plan: free trial.
- Best for: SMB sales and support teams wanting fast self-serve setup
- Strengths: Call Flow Designer (drag-and-drop IVR), all tiers; Skill- and condition-based routing (Essential and up); VIP call queues (Expert).
Where it falls short
Call recording retention is capped at one month on Lite and Starter, and those two entry tiers also leave out keypad IVR routing, skill-based routing and CRM integrations, which start at Essential.
Wrong for
A large blended contact center that needs deep omnichannel routing or predictive dialing built in rather than bolted on.
Visit CloudTalk →
#5 Aircall
250+ integrations and AI voice agents, from $30/license/month · France · aircall.io
250+ integrations Published entry pricing European vendor
Aircall's pitch is breadth: 250-plus native integrations, more than any other vendor reviewed here, which is why it is usually bought as a calling layer dropped into an existing CRM or helpdesk rather than as a standalone contact center.
- Pricing: Per license / month. Essentials $30/license/month and Professional $50/license/month, billed annually (25% below monthly billing), both with a 3-license minimum. Free plan: free trial.
- Best for: Teams that live inside a CRM or helpdesk already
- Strengths: IVR and time/date-based routing; Call queuing with ring groups; Call recording and transcription.
Where it falls short
Smart routing that reads live CRM data, queue callback and the Power Dialer are held back for Professional and Enterprise, and Enterprise itself is quote-only with a 25-license minimum, a large jump from the 3-license entry tiers.
Wrong for
A team building a contact center from scratch with no existing CRM to plug into; the integration advantage disappears without one.

#6 Ringover
AI receptionist bundled in, buyable online without a sales call · France · ringover.com
Buyable online AI receptionist included European vendor
Ringover's Talk plan is one of the only entries in this category a buyer can purchase online without a sales call, and it bundles an AI-powered virtual receptionist with call transcription and summaries by default rather than as an upsell.
- Pricing: Per user / month. Talk plan published entry pricing, buyable online. Free plan: none.
- Best for: Small teams that want self-serve setup with AI transcription
- Strengths: AI-powered virtual receptionist; Call recording, summaries and transcription; Advanced IVR with intelligent routing (Business).
Where it falls short
The step up to Business is a real commitment, not a soft upgrade: a three-seat minimum and a 12-month term apply.
Wrong for
A team that wants omnichannel digital channels included in the base price; those are add-ons here, not a bundled feature.
Visit Ringover →
#7 Diabolocom
Enterprise predictive dialing, published from ~$60/license · France · diabolocom.com
Predictive dialing 150-license minimum European vendor
Diabolocom, with two decades in this category from Paris, is one of the few enterprise-grade CCaaS platforms here that publishes an indicative starting price at all, covering smart IVR, skills-based ACD, queue callback and preview, progressive and predictive dialer modes with answering-machine detection, aimed at outbound-heavy and blended operations, with real-time supervision, interaction recording and native CRM integrations in the entry Voice plan.
- Pricing: Per named license, 3-year term. Voice from ~$60/named license. Free plan: none.
- Best for: Enterprise outbound and blended contact centers
- Strengths: Smart IVR; Skills-based ACD; Queue callback.
Where it falls short
The published price comes with real strings attached: a three-year commitment and a 150-named-license minimum, which puts it out of reach for any team smaller than a real enterprise contact center, plus usage charges for voice minutes, transcription and storage.
Wrong for
Any team below roughly 150 seats; the published pricing model assumes an enterprise deployment from the start.

#8 3CX
Per-simultaneous-call licensing with a self-hosted option · Cyprus · 3cx.com
Self-hostable Per-call licensing European vendor
3CX prices differently from every other vendor reviewed here: instead of a per-agent seat, it licenses per simultaneous call, which can cost less than seat-based pricing for an organization with many named users who are rarely all on a call at once.
- Pricing: Per simultaneous call / year. Basic, PRO and AI editions licensed annually per simultaneous-call tier (8 to 1,024 SC). Free plan: free plan.
- Best for: Organizations wanting self-hosted deployment or many named users with few concurrent calls
- Strengths: Call queues and wallboards (PRO and AI editions); Interactive voice response; Self-hosted, cloud or partner-hosted deployment.
Where it falls short
The call center module (queues, IVR, wallboards, reporting) sits on top of 3CX's core PBX rather than standing alone as an agent-first CCaaS platform.
Wrong for
A buyer specifically wanting a purpose-built, agent-first contact center rather than a call-center module bundled with a general business phone system.

#9 Genesys Cloud CX
Largest scale in this category, published tiered pricing · United States · genesys.com
25 billion interactions/year Published tiered pricing US-headquartered
Genesys traces back to 1990 and now operates out of Menlo Park, California, serving more than 8,000 organizations in over 100 countries and orchestrating roughly 25 billion contact center interactions a year, among the largest scale of any vendor in this category.
- Pricing: Per user / month, tiered. CX 1 (voice) $75, CX 2 (adds digital) $115, CX 3 (adds workforce management) $155 and CX 4 (AI) $240 per user/month billed annually, published. Free plan: none.
- Best for: Large enterprises wanting the most established CX platform brand
- Strengths: Voice and digital omnichannel routing; IVR flow builder; Workforce management (CX 3 and up).
Where it falls short
A $2,000-a-month minimum commitment applies regardless of actual headcount, and full digital-plus-workforce-management capability requires stacking to the pricier tiers.
Wrong for
A small or mid-sized team below the $2,000/month minimum commitment; the pricing structure assumes a larger deployment.

#10 NICE CXone
Routing, quality and workforce management in one suite · Israel / United States · nice.com
Published 5-tier pricing Dual HQ: Israel & US Routing + QM + WFM in one suite
NICE CXone is the contact-center cloud platform of NICE Ltd., originally founded in Israel in 1986 and now dual-headquartered in Ra'anana, Israel and Hoboken, New Jersey.
- Pricing: Per agent / month, 5 tiers. Omnichannel Suite $110, Essential Suite $135, Core Suite $169, Complete Suite $209 and Ultimate Suite $249 per agent/month, published. Free plan: none.
- Best for: Large enterprises consolidating multiple CX point tools into one vendor
- Strengths: Omnichannel routing; Quality management; Workforce management and scheduling.
Where it falls short
It is not genuinely self-serve: the five-tier structure, while unusually transparent for a suite at this scale, makes like-for-like comparison with flatter-priced competitors harder, and it is aimed squarely at large enterprises consolidating multiple existing tools rather than a small team buying its first contact center.
Wrong for
A small team wanting one simple price; the five-tier suite structure is built for enterprise procurement, not quick comparison shopping.
Visit NICE CXone →
#11 Vocalcom
Operating since 1995, native predictive dialing · France · vocalcom.com
Operating since 1995 Native predictive dialing European vendor
Vocalcom is one of the oldest names in this category, operating since 1995 with its registered office in Courbevoie, just outside Paris, and reporting 1,200-plus customers, 550,000-plus users in 47-plus countries and roughly a billion interactions a year, with particular depth in financial services, insurance and outsourcing operations including debt collection.
- Pricing: Quote only. Enterprise CCaaS pricing quoted on request. Free plan: none.
- Best for: Financial services, insurance and outsourcing operations
- Strengths: Automatic call distribution; Native predictive dialing; Omnichannel (SMS, web, chat, email, WhatsApp, social).
Where it falls short
Like most of the enterprise vendors on this list, pricing is quoted per deployment rather than published anywhere, and the go-to-market is enterprise sales rather than same-day self-serve signup.
Wrong for
A small business wanting transparent, published pricing before a sales call; Vocalcom does not publish a number anywhere.

#12 NFON
Contact center on European-hosted cloud telephony · Germany · nfon.com
European-hosted data DACH-region focus European vendor
NFON, a Munich vendor operating since 2007 with 54,000-plus customers, sells its contact-center product, now branded NFON Contact Center, alongside its Cloudya cloud telephony, routing calls, email, chat and messaging by intent, skills and queue status.
- Pricing: Quote only. NFON Contact Center pricing quoted on request, sold alongside NFON's Cloudya cloud telephony. Free plan: none.
- Best for: German and DACH-region SMEs already using or buying Cloudya telephony
- Strengths: Omnichannel workspace (calls, email, chat, messaging); Routing by intent, skills, priority and queue status; AI Agent Assist (summaries, suggested responses).
Where it falls short
Pricing is not published anywhere on the site.
Wrong for
A company outside the DACH region that wants published pricing or deep digital-channel and AI features.

#13 Enreach
Pan-European group spanning 10 countries · Netherlands · enreach.com
10 European countries Bundled with UCaaS European vendor
Enreach is a pan-European communications group headquartered in Almere, the Netherlands, formed in 2018 when several national telecom brands, including Voiceworks and Swyx, combined under investor Waterland and later rebranded.
- Pricing: Quote only. Enreach Omnichannel contact center pricing quoted on request. Free plan: none.
- Best for: Mid-sized European organizations wanting one vendor for UCaaS and CCaaS
- Strengths: Omnichannel contact center; Bundled unified communications (UCaaS); National reseller and partner network.
Where it falls short
Because it grew by consolidating national brands, both product experience and public documentation vary by country, strongest in the Netherlands, Germany and UK.
Wrong for
A buyer wanting one consistent product experience across every European market; Enreach's experience varies noticeably by country.

#14 Five9
Large US pure-play cloud contact center, published entry price · United States · five9.com
Published entry tier Predictive & power dialers US-headquartered
Five9 has operated since 2001 out of San Ramon, California, and is among the largest pure-play cloud contact center vendors globally, reporting more than 3,000 customers and 14 billion-plus call minutes recorded a year.
- Pricing: Per concurrent seat / month + custom tiers. Digital $119 and Core $159 per concurrent seat/month, published, 50-seat minimum, usage charges for AI minutes and SMS. Free plan: none.
- Best for: Voice-first enterprise contact centers wanting predictive/power dialers
- Strengths: Inbound and outbound voice routing; Predictive and power dialers; AI summaries, live transcription and agent assist in every bundle.
Where it falls short
Plus, Pro and Enterprise, the bundles with advanced AI and full workforce engagement, are custom-quoted, and even the published bundles require a 50-seat minimum plus usage charges for AI minutes and SMS.
Wrong for
A team below 50 agents.
Visit Five9 →
#15 RingCentral RingCX
Bundled with RingCentral UCaaS, published entry price · United States · ringcentral.com
Bundles with RingCentral UCaaS 20+ digital channels US-headquartered
RingCentral sells its contact center product, RingCX, as an extension of its broader UCaaS platform rather than a standalone acquisition, so a company already on RingCentral for phone and messaging can add contact-center capability under one vendor relationship.
- Pricing: Per user / month + custom tiers. Standard $65/user/month (annual) or $75/month, published; Professional, Elite and Enterprise all custom-quoted. Free plan: none.
- Best for: Organizations already using RingCentral for unified communications
- Strengths: 20+ digital channels; Automatic call distribution; IVR and skills-based routing.
Where it falls short
Professional, Elite and Enterprise are all custom-quoted, and RingCX runs as a separate license from RingCentral's core UCaaS plans rather than one combined bill.
Wrong for
A buyer evaluating contact centers independently of any existing UCaaS relationship; the bundling advantage disappears without one.

Questions and answers
What is the best call center software in 2026?
Kavkom ranks first of 15, best for small French/European sales teams on a tight budget. Odigo is second (large enterprises that require a sovereign-cloud deployment) and Puzzel third (nordic and UK organizations wanting AI assistance for live agents). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Is call center software the same thing as CCaaS?
In practice, yes, on this page. CCaaS (contact center as a service) is the vendor term for cloud-hosted call center software sold as a subscription rather than installed on-premises hardware.
Which call center tools publish their pricing?
Nine of the fifteen publish at least an entry-tier price rather than quoting every plan: CloudTalk (from €19/user/month), Aircall (from $30/license/month billed annually), Kavkom (from €10/user/month), Ringover (published entry tier, buyable online), Diabolocom (from ~$60/named license, 3-year minimum), Five9 (Digital at $119 and Core at $159 per concurrent seat/month, 50-seat minimum), RingCentral RingCX (Standard at $65/user/month), Genesys Cloud CX (CX 1 at $75/user/month) and NICE CXone (Omnichannel Suite at $110/agent/month).
Is there a free call center tool?
Only at the phone-system end. 3CX still offers free editions for up to 10 users, a self-hosted 4SC Free Basic and a shared SMB instance, but they leave out CRM integration and the paid editions' wallboards and queue reporting.
Which call center software can you self-host?
3CX is the clearest case among the fifteen reviewed here. It can run self-hosted on a customer's own server, on 3CX's cloud, or through a hosting partner, and its free 4SC Basic edition is self-hosted only.
Which of these vendors are headquartered in the EU or EEA?
Eleven of fifteen: CloudTalk (Slovakia), Aircall and Kavkom and Ringover and Diabolocom and Odigo and Vocalcom (all France), 3CX (Cyprus), NFON (Germany), Enreach (Netherlands) and Puzzel (Norway, in the EEA rather than the EU itself).
Why don't Five9, RingCentral, Genesys and NICE CXone rank at the top despite being the biggest names?
Market share is not one of our ranking criteria, and neither is where a vendor is headquartered. Genesys Cloud CX and NICE CXone publish every tier's price, which puts them ninth and tenth, while quote-only enterprise vendors publish nothing.
Which tool is best for enterprise outbound and predictive dialing?
Diabolocom and Vocalcom both offer genuine predictive dialing built for outbound-heavy and blended operations, Diabolocom with preview, progressive and predictive modes plus answering-machine detection and Vocalcom pairing dialing with its Hermes AI analytics suite.
Do any of these vendors qualify under EEA rather than EU ownership?
Puzzel does. It is headquartered in Oslo, Norway, which sits in the European Economic Area rather than the EU itself. Norway's inclusion in the EEA means Puzzel is subject to much of the same data-protection framework as an EU-headquartered vendor.
How often is this call center software ranking updated?
Whenever a fact underneath it changes: a pricing update, an acquisition, or a product that stops being maintained.
