If you've been using Zadarma for your business calls, you've probably noticed a few limitations. The interface feels a bit dated, the verification process during account setup can drag on, and while the pricing looks attractive on paper, the feature set doesn't always match what modern sales teams need.

Maybe you're looking for stronger CRM integrations. Perhaps you need AI that actually saves you time. Or you simply want a phone system that was designed for how teams work today—mobile-first, always connected, and smart enough to handle the admin work.

Whatever brought you here, you're not alone. Zadarma has served European SMBs well since 2006, but the VoIP landscape has evolved dramatically. New players have emerged with AI-native platforms, while established providers have added features that Zadarma hasn't matched.

In this guide, we'll walk through seven Zadarma competitors worth considering. Each brings something different to the table—from budget-friendly options to enterprise-grade solutions. We'll break down pricing, features, and where each one shines so you can find the right fit for your team.

Allo, Best for Small Sales Teams

What is Allo?

Allo represents a new generation of business phone systems built from the ground up for the AI era. Founded in 2024 by Jérémy Goillot, a former employee at unicorn fintech Spendesk, the company set out to solve a specific problem: sales teams were drowning in admin work instead of actually selling.

Rather than retrofitting AI onto legacy infrastructure like many Zadarma competitors, Allo was designed mobile-first and AI-native from day one. The company brings a fresh perspective to a market dominated by decade-old platforms.

What makes Allo stand out isn't just the technology—it's the philosophy. Every call gets recorded, transcribed, and synced to your CRM automatically. Your AI receptionist handles incoming calls while you focus on prospects. And the pricing? Straightforward. No hidden fees or confusing add-on menus.

Why Allo is a Good Alternative to Zadarma

Where Zadarma charges €0.01/minute for call transcription and keeps AI answering service pricing hidden, Allo includes all AI features in every plan. That's a fundamental difference in approach.

The CRM integration story is also stronger with Allo. While Zadarma's HubSpot integration sits at 3.5/5 on the marketplace, Allo maintains a perfect 5/5 rating with over 200 installs. The integration doesn't just log calls—it syncs recordings, transcriptions, and even updates contact records automatically.

For mobile-first sales teams, Allo delivers what Zadarma's "dated" interface struggles to match. The app was designed for people who spend their days on the move, not sitting at desks. Call quality remains consistent whether you're in the office or working from a coffee shop.

Allo also supports local numbers in 50+ countries, giving you solid international coverage without the complexity of Zadarma's European-focused setup.

Allo Pricing

• Starter: $25/month for a single user. Includes unlimited calls, a local phone number, AI summaries, and IVR—everything you need to get started.

• Business: $45/month per user. Adds integrations with your CRM, unlimited AI answering service, SMS, and international calling capabilities.

Both plans come with a 7-day free trial. No add-ons, no surprises. The price you see is the price you pay.

Justcall, Best for Sales Teams That Need a Power Dialer

What is Justcall?

Justcall emerged from India-based SaaS Lab in 2016 with a clear mission: eliminate the repetitive tasks that eat into selling time. The founding team recognized that sales reps were spending hours logging calls and updating CRMs instead of talking to prospects.

Today, Justcall has evolved into a comprehensive unified communications platform supporting voice, SMS, email, and WhatsApp. The company particularly appeals to teams that need outbound calling power—their dialer capabilities have become a signature feature that Zadarma simply doesn't offer.

What sets Justcall apart from other Zadarma competitors is the depth of their sales-specific tooling. Beyond basic calling, they've built sentiment analysis, call scoring, and AI coaching directly into the platform. For managers who need visibility into team performance, these features provide actionable insights.

Why Justcall is a Good Alternative to Zadarma

The power dialer alone makes Justcall worth considering if outbound calling drives your business. Zadarma doesn't offer anything comparable, and the productivity gains from automated dialing can be substantial for high-volume teams.

Justcall operates in 70+ countries with local numbers, covering more ground than Zadarma's European focus. Their CRM integrations also run deeper—the HubSpot integration holds a 4/5 rating on the marketplace, and they support native connections to Salesforce, Pipedrive, and dozens of other tools.

The AI answering service can qualify leads and book appointments without human intervention. While Zadarma offers similar functionality, the pricing transparency differs. Justcall clearly states: $99/month for the AI Voice Agent with 100 minutes included.

One consideration: Justcall requires a minimum of two licenses, so solo users should look elsewhere. But for teams of two or more, the platform scales nicely.

Justcall Pricing

• Team: $39/user/month (minimum 2 licenses). Includes unlimited calls in the US/Canada, AI transcription, a local number, SMS, WhatsApp messaging, and CRM integrations.

• Pro: $69/user/month (minimum 2 licenses). Adds power dialer, bulk SMS, Salesforce integration, roles and permissions, and advanced reporting.

• Pro Plus: $109/user/month. Includes real-time agent assist, sentiment analysis, and call scoring.

AI add-ons: AI Review Assist costs $9/user/month. AI Voice Agent runs $99/month with 100 minutes included.

14-day free trial available.

Aircall, Best for Mid-Size Teams That Need Enterprise Features

What is Aircall?

Aircall launched in Paris in 2014 to challenge the hardware-heavy phone systems that dominated the market. The founders believed business calling should be as simple as consumer apps—and they've largely delivered on that vision. By 2025, the company surpassed $175 million in annual recurring revenue.

The platform carved out a strong position in the mid-market segment, serving teams that have outgrown basic VoIP but don't need full contact center complexity. Their sweet spot? Companies with 10-200 employees who want reliability and polish without enterprise overhead.

Aircall's approach prioritizes CRM connectivity above almost everything else. Early on, they recognized that a phone system disconnected from your sales tools creates friction. Today, their integrations with Salesforce, HubSpot, and Zendesk rank among the most robust in the industry.

Why Aircall is a Good Alternative to Zadarma

If integration quality matters to your workflow, Aircall delivers what Zadarma can't. The native connections go beyond simple call logging—they enable advanced workflows, automatic data sync, and seamless handoffs between tools.

Aircall's 38-country coverage includes regions where Zadarma's European focus leaves gaps. For teams selling into North America, Asia-Pacific, or Latin America, that geographic flexibility proves valuable.

The call monitoring features—listen, whisper, and barge capabilities—support team coaching in ways that Zadarma's basic setup doesn't allow. Managers can join live calls to guide new reps or handle escalations without the customer knowing.

That said, Aircall comes with tradeoffs. The three-license minimum means you're paying at least $120/month before anyone makes a call. AI features only work in English and French. And the support experience varies depending on your team size—smaller accounts sometimes report feeling deprioritized.

Aircall Pricing

• Essentials: $40/license. Includes a local number, unlimited calls within the US and Canada, IVR, call recording, and SMS/MMS.

• Professional: $70/license. Adds advanced analytics, sales features including Power Dialer and Voicemail Drop, and unlimited call recordings.

Minimum 3 licenses required. 7-day free trial available.

Notable add-ons: AI Voice Agent ($0.49/minute), WhatsApp ($10/month/user), Analytics+ ($15/user/month).

Cloudtalk, Best for International Sales Operations

What is Cloudtalk?

Cloudtalk was founded in Slovakia by Martin Malych and Viktor Vanek, who identified an opportunity to serve sales and support teams with a platform optimized for global operations. Since 2016, the company has grown to serve 4,000 customers across 100 countries, with offices spanning Europe, Canada, and Mexico.

The platform distinguishes itself through exceptional international coverage. While many Zadarma competitors focus primarily on US and European markets, Cloudtalk supports local numbers in 160+ countries. For sales teams prospecting across multiple regions, this coverage eliminates the friction of managing separate phone systems.

Cloudtalk has also invested heavily in AI-powered outbound capabilities. Their AI voice agents can place calls autonomously, qualifying leads and booking meetings without human intervention. This functionality goes well beyond what Zadarma offers.

Why Cloudtalk is a Good Alternative to Zadarma

The international calling infrastructure alone justifies considering Cloudtalk over Zadarma. Local numbers in 160 countries versus Zadarma's European focus—it's not even close for teams with global ambitions.

The smart dialer feature automatically selects business numbers with local area codes matching your prospects' numbers. This "local presence" capability significantly improves pickup rates compared to calling from foreign numbers.

Cloudtalk's AI features include real-time transcription, sentiment analysis, and topic extraction. While Zadarma offers call transcription, it charges €0.01/minute. Cloudtalk bundles these capabilities into their plans more transparently.

The platform integrates natively with 70+ tools including Salesforce, HubSpot, Pipedrive, and Outreach. Their HubSpot integration maintains a 4.3/5 rating on the marketplace—respectable, though not quite matching Allo's perfect score.

Cloudtalk Pricing

• Lite: $27/month/user. Includes unlimited domestic calls and local numbers in 160+ countries. However, integrations aren't included and most features are limited.

• Essential: $39/month/user. Adds business hours, IVR, ring groups, and integrations.

• Expert: $69/month/user (minimum 3 licenses). Includes power dialer, live monitoring, advanced reporting, and WhatsApp support.

AI voice agents are billed separately.

14-day free trial available, no credit card required.

Quo, Best for Small Teams That Value Simplicity

What is Quo?

Quo (formerly known as OpenPhone) launched in 2018 with a straightforward premise: business phone systems shouldn't require IT expertise to set up and manage. The platform appeals to SMBs and small teams who want professional calling capabilities without enterprise complexity.

What makes Quo distinctive is its approach to team collaboration. The shared inbox supports threads and tagging, letting multiple team members handle customer communications without stepping on each other. An internal chat keeps team discussions separate from customer conversations.

The platform also includes a lightweight CRM built directly into the phone system. For teams not ready to invest in Salesforce or HubSpot, this bundled functionality provides basic contact management without additional subscriptions.

Why Quo is a Good Alternative to Zadarma

Quo's interface is noticeably cleaner than Zadarma's dated design. The platform feels modern and intuitive—most teams can start making calls within minutes of signing up.

The starting price of $19/user/month undercuts both Zadarma's Office plan (€37/month) and most other alternatives on this list. For budget-conscious teams that don't need advanced features, Quo delivers solid value.

The AI answering service, called Sona, handles incoming calls intelligently. While 10 calls come included in all plans, additional usage costs $0.75/call—more transparent pricing than Zadarma's unlisted AI rates.

Quo supports call transcriptions and summaries in 34 languages, covering more ground than many competitors' English-only AI. The platform integrates with HubSpot, Salesforce, and Jobber, plus Zapier and Make for custom workflows.

One important caveat: Quo prohibits cold calling and may block accounts they suspect of violating this rule. If outbound prospecting drives your sales motion, choose a different platform.

Quo Pricing

• Starter: $19/user/month. Includes a local number, unlimited calling and messaging to US and Canadian numbers, voicemail transcripts, and 10 calls handled by Sona AI.

• Business: $33/user/month. Adds AI call summaries and transcripts, group calling, call transfers, analytics, and HubSpot/Salesforce integrations.

• Scale: $47/user/month. Includes dedicated onboarding support, priority support, and inbound phone support.

7-day free trial available.

Dialpad, Best for AI-First Mid-Market Teams

What is Dialpad?

Dialpad carries an unusual pedigree in the VoIP space. Founder Craig Walker previously created GrandCentral—the service Google acquired and transformed into Google Voice. After that exit, Walker started Dialpad in 2011 as an entrepreneur in residence at Google, and half of the company's first 30 hires came from Google.

That DNA shows in Dialpad's approach to AI. Rather than licensing third-party models, the company has developed its own AI technology since 2018. This proprietary foundation powers features like real-time transcription, live coaching, and call scoring that feel more tightly integrated than bolted-on alternatives.

Dialpad maintains three distinct products: Connect for general business communications, Support for customer service teams, and Sell for sales organizations. Each comes with tailored features and pricing for its specific use case.

Why Dialpad is a Good Alternative to Zadarma

Dialpad includes AI features in all plans at no extra cost—a stark contrast to Zadarma's per-minute transcription charges. Call summaries, live coaching suggestions, and call scoring come standard.

The platform supports 50+ countries for local numbers, matching or exceeding Zadarma's coverage. The integration ecosystem is also more mature, with native connections to all major CRMs and productivity tools.

For teams that value call intelligence, Dialpad's proprietary AI delivers genuinely useful insights. The system can identify coaching opportunities, track talk-to-listen ratios, and surface patterns across thousands of calls.

The tradeoffs? Some users report call quality issues, and the learning curve can be steeper than simpler alternatives. Support response times also draw occasional criticism, particularly for smaller accounts.

Dialpad Pricing

• Standard: $27/user/month. Includes unlimited calling (your country, US, and Canada), a local number, call forwarding, call recording, and up to 3 departments.

• Pro: $35/user/month. Adds SSO, phone support, and up to 25 departments.

AI features are included in all plans.

Additional products (Support and Sell) carry separate pricing structures.

Vonage Business, Best for Large Teams with Complex Call Routing

What is Vonage Business?

Vonage has been in the communications business since 2001, evolving from a residential VoIP pioneer into a comprehensive unified communications platform. The company now serves medium to large organizations, particularly those with sophisticated call management requirements.

The platform's strength lies in advanced call handling. Features like call announce, call screening, call park, and call queue provide granular control over how incoming calls flow through your organization. For companies with dedicated reception staff or complex routing needs, this depth proves valuable.

Why Vonage is a Good Alternative to Zadarma

Vonage supports 90+ countries for local numbers, substantially expanding on Zadarma's European coverage. For companies with distributed teams or international customers, this reach matters.

The advanced call management features exceed what either Zadarma or most other alternatives offer. Call tagging, call conferencing, call flip between devices—these capabilities support workflows that simpler platforms can't handle.

The AI virtual assistant handles calls, answers FAQs, and routes callers using voice-activated IVR. While Zadarma offers similar functionality, Vonage's implementation supports 20+ languages out of the box.

The 27 native integrations include connections to Salesforce, Microsoft Teams, Slack, and HubSpot. However, the HubSpot integration reviews are notably poor, so test thoroughly before committing.

Vonage's main drawback: essential features like call recording and visual voicemail are locked to higher-tier plans, and add-on fees accumulate quickly.

Vonage Pricing

• Basic: $19.99/user/month (plus taxes and fees). Includes unlimited domestic calling and SMS/MMS.

• Premium: $29.99/user/month. Adds unlimited video meetings (up to 200 participants) and team messaging.

• Advanced: $39.99/user/month. Adds on-demand call recording (15 hours/month) and visual voicemail with transcription.

Notable paid add-ons: Business call recording at $49.99/month, business inbox at $9.99/month, local business phone at $4.99/month.

Conclusion

Choosing a Zadarma alternative comes down to matching your team's priorities with each platform's strengths.

For small sales teams that want simplicity and AI-powered efficiency, Allo delivers the most complete package at $45/user/month with no add-ons or complexity. The mobile-first design and strong CRM integrations make it ideal for teams that sell on the go.

For teams that need power dialing capabilities, Justcall's outbound tools and comprehensive feature set justify the higher price point, especially as you scale.

For international operations, Cloudtalk's 160-country coverage and local presence features remove friction from global sales.

For budget-conscious small teams, Quo's $19 starting price and clean interface offer solid value, though the cold calling restrictions may be a dealbreaker for some.

For mid-market teams prioritizing AI, Dialpad's proprietary technology and included AI features provide depth that Zadarma can't match.

For large organizations with complex routing, Vonage's advanced call management capabilities handle workflows that simpler platforms struggle with.

The VoIP market has evolved dramatically since Zadarma launched in 2006. Modern alternatives offer AI automation, deeper integrations, and mobile-first design that transform how sales teams communicate. The right choice depends on your team size, budget, and workflow requirements—but you have more options than ever.
