Since Skype for Business was discontinued, many companies have turned to heavy collaboration tools like Teams or Zoom. But if all you need is simple, affordable international calling, ZenCall offers pay-as-you-go rates from $0.02/minute—directly in your browser.
Skype for Business was officially discontinued in 2021, leaving many companies scrambling for alternatives that could maintain their international calling capabilities without disrupting operations. While Microsoft Teams absorbed many features from Skype for Business, not every business wants or needs a full collaboration suite just to make international calls.
In 2025, several strong alternatives exist for organizations that need affordable, reliable international calling—including ZenCall, a browser-based pay-as-you-go platform that prioritizes simplicity and cost-effectiveness over feature bloat.
The discontinuation of Skype for Business marked the end of an era for many companies that had relied on it for years. Organizations found themselves forced to evaluate new solutions, often discovering that their needs had evolved beyond what Skype for Business originally provided. Some companies needed comprehensive unified communications platforms with chat, video, and collaboration tools. Others simply required a reliable, affordable way to make international business calls without the complexity or cost of enterprise software suites.
Understanding which alternative fits your organization depends on your specific needs, budget, team size, and technical requirements. Let's examine what happened to Skype for Business and explore the best alternatives available today.
The timeline of Skype for Business's decline provides context for why businesses need new solutions:
Skype for Business Online was retired in July 2021 after Microsoft announced the end-of-life date years in advance. This gave businesses time to plan migrations, but the transition still disrupted many organizations that had built workflows around Skype for Business functionality.
The on-premises Skype for Business Server continued for a while longer but has also been deprecated, with Microsoft providing only minimal support and no significant updates or improvements.
Microsoft encouraged users to migrate to Teams, positioning it as the natural successor with enhanced capabilities. Teams inherited many Skype for Business features while adding modern collaboration tools, deep Microsoft 365 integration, and improved user interfaces.
For organizations already invested in the Microsoft ecosystem with Office 365 or Microsoft 365 subscriptions, Teams seemed like the obvious choice. However, this "obvious" solution came with significant drawbacks for certain types of businesses.
Many businesses wanted something simpler, cheaper, and dedicated to calling rather than a comprehensive collaboration platform. The issues with Teams as a Skype for Business replacement include:
This mismatch between what Teams offers and what many businesses actually need created an opportunity for alternative solutions that focus specifically on calling without the overhead.
Let's examine the leading alternatives, their strengths, weaknesses, and ideal use cases:
Microsoft Teams offers a full collaboration suite including chat, meetings, file sharing, and calling—essentially replacing not just Skype for Business but multiple communication tools.
Best for: Enterprises already in the Microsoft ecosystem with Office 365 or Microsoft 365 subscriptions who need comprehensive unified communications.
Advantages:
Downside: Teams represents overkill and becomes expensive if you just need international calling. The Phone System add-on costs $8-$15 per user monthly, and calling plans add even more. For a team of 10 people making occasional international calls, this quickly becomes hundreds of dollars monthly for features they don't use.
Additionally, Teams' complexity means training time, administrative overhead, and potential resistance from team members who find it overwhelming compared to simpler tools they previously used.
Zoom Phone is built on Zoom's proven video platform, extending the reliability and ease of use that made Zoom's meetings popular into voice calling.
Best for: Companies already using Zoom meetings who want integrated calling capabilities and a consistent user experience across video and voice.
Advantages:
Pricing: Typically $10–$20 per user per month depending on features and calling plans.
Considerations: Like Teams, Zoom Phone works best when you're already invested in the Zoom ecosystem and need the full suite of features. For businesses only needing occasional international calling, the per-user monthly fees add up quickly.
Vonage Business provides a cloud PBX with advanced features including auto-attendants, call routing, voicemail-to-email, and extensive integrations with business software.
Best for: Medium-sized businesses needing a complete phone system with features like call queues, extensions, and sophisticated call routing.
Advantages:
Pricing: Starting at $19.99+ per line per month, with costs increasing for advanced features and international calling.
Considerations: Vonage excels as a complete business phone system replacement but represents more infrastructure and cost than businesses need if they're primarily making occasional international calls rather than running a full call center or phone-dependent operation.
ZenCall offers a simple pay-as-you-go calling platform focused specifically on international calling without the complexity of full unified communications suites.
Best for: Small teams, startups, freelancers, and any business needing affordable international calls without monthly subscriptions or feature bloat.
Key Features:
Advantages:
Check exact rates for any destination using ZenCall's rate calculator to know your costs before you dial.
For many businesses that used Skype for Business primarily for international calling, ZenCall provides everything they need without the excess:
Only pay for the minutes you use with no monthly per-user charges. If your team makes 500 minutes of international calls monthly, that costs just $10 with ZenCall versus potentially hundreds of dollars with per-user subscription services. This cost structure is particularly advantageous for:
No downloads, hardware, or IT setup required. Team members simply visit the ZenCall website, log in, and start calling. There's no software to install, no configuration needed, and no technical hurdles preventing adoption. This accessibility means:
Add call credits for your team without subscription bloat. Whether you have 2 people or 20 making international calls, you simply add credit as needed. No need to predict usage, commit to user counts, or manage complex subscription tiers. Scaling up means adding more credit; scaling down means simply not adding credit. This flexibility is invaluable for growing businesses or those with changing needs.
Flat international rates with no hidden fees mean you always know exactly what you're paying. Unlike services with connection fees, maintenance charges, or variable pricing based on destination and number type, ZenCall maintains simple, predictable pricing. Save frequently called numbers with ZenCall's contacts feature to make repeat calls even faster.
ZenCall's browser-based approach represents the future of international calling, eliminating the need for complex software installations, reducing security vulnerabilities, and ensuring universal compatibility. Browser-based calling means:
ZenCall is particularly well-suited for specific business scenarios:
Startups and small teams who need international calls but not enterprise software benefit from ZenCall's simplicity and low cost. When you're focusing on building your business, you don't need to also become an expert in unified communications platforms.
Freelancers and consultants who don't want a monthly subscription appreciate paying only for actual usage. When some months you make many international calls and other months you make none, pay-as-you-go makes perfect economic sense.
Travelers and expats who occasionally need business-quality international calling can use ZenCall from anywhere in the world without worrying about roaming charges, local SIM cards, or maintaining expensive subscriptions they only use periodically.
Any organization watching costs carefully will appreciate ZenCall's transparent pricing and the ability to drastically reduce international calling expenses compared to traditional business phone services.
Choosing the right Skype for Business alternative depends on your specific situation:
Let's examine costs for a 10-person team making 1,000 minutes of international calls monthly:
Microsoft Teams Phone System:
Zoom Phone:
Vonage Business:
ZenCall:
The savings with ZenCall for this usage pattern exceed $100-380 per month, or $1,200-4,560 annually—money that could fund hiring, marketing, or business development instead of communication overhead.
Skype for Business may be gone, but your options aren't limited—in fact, you likely have better alternatives now than when Skype for Business was in its prime.
For many businesses, the death of Skype for Business is actually an opportunity to reevaluate needs and choose a solution that better fits current requirements rather than legacy workflows.
