Top 6 Benefits of Teams Calling

Is your business phone system holding you back? Many businesses are still using legacy PBX systems or outdated VoIP solutions, unaware that a modern alternative exists.
These older phone systems lack flexibility, increase operational costs, and create unnecessary IT burdens. As more businesses embrace remote and hybrid work, traditional phone systems fail to support seamless communication across teams and locations.
Microsoft Teams has quickly become the dominant collaboration platform, with over 280 million users worldwide. While many businesses use it for chat, video calls, and file sharing, fewer realize its potential as a fully integrated VoIP phone system.
This article explores the top benefits of Microsoft Teams Calling, including cost savings, security enhancements, scalability, and advanced calling features. We’ll also highlight how seamless integration with Microsoft 365 improves business efficiency and why now is the best time to migrate.
Microsoft Teams Calling: An All-in-One UCaaS Solution
Before we dive into the details of Microsoft Teams Calling, let’s take a moment to discuss the benefits of a VoIP phone system. Why do modern businesses need a solution like Microsoft Teams Calling?
First, a VoIP phone system allows businesses to eliminate traditional, on-premises PBX phone systems. These legacy solutions are more expensive and less flexible than VoIP, making them less than ideal in the modern age.
Microsoft Teams Calling specifically allows organizations to make and receive calls, integrate with Microsoft 365, and more, all without sacrificing the enterprise-grade security of the system.
With this context in mind, let’s take a look at why so many businesses are making the switch to Microsoft Teams Calling.
Why Businesses Are Migrating to Microsoft Teams Calling
The Shift from Legacy PBX to VoIP
For some time time now we have witnessed the steady migration from traditional phone systems to VoIP solutions. VoIP technology enables voice and video calls over the internet, eliminating the need for legacy phone lines. Businesses are making the switch for several reasons:
- Lower costs: Reduces reliance on expensive, outdated PBX systems.
- Scalability: Easily supports remote teams and multi-location businesses.
- Advanced features: Provides call forwarding, voicemail, and video conferencing in one platform.
By integrating VoIP with Microsoft Teams, businesses can seamlessly make and receive calls through the Teams app or even physical desk phones, offering a flexible and unified calling experience.
Top 6 Key Benefits of Microsoft Teams Calling:
1. Cost Savings and ROI Analysis
Switching to Microsoft Teams Calling can significantly reduce telecom expenses compared to legacy PBX systems. Traditional phone systems come with high maintenance costs, expensive hardware upgrades, and separate carrier fees.
- By moving to Teams Calling, businesses can:
- Eliminate PBX hardware costs, reducing capital expenditures.
- Cut operational expenses by consolidating voice and collaboration tools under Microsoft 365.
- Lower IT maintenance costs, as Teams Calling requires no on-premise hardware.
For example, companies that switch from traditional PBX to Microsoft Teams Calling with Direct Routing can reduce telecom costs by up to 30-40%, depending on the size and complexity of their previous system.
2. Enhanced Security & Compliance
Security and compliance are critical considerations when choosing a communication platform. Microsoft Teams Calling is built with enterprise-grade security, ensuring data privacy, encryption, and regulatory compliance.
Key security features include:
- End-to-end encryption for voice and video calls when both ends of the call are MS Teams.
- Multi-factor authentication (MFA) to prevent unauthorized access.
- Regular security updates to protect against evolving threats.
Additionally, Microsoft Teams Calling meets major industry compliance standards such as GDPR, HIPAA, and ISO 27001, making it a trusted solution for healthcare, finance, and government organizations.
Microsoft also offers Direct Routing for GCC High licenses for government agencies and Department of Defense contractors. However, to make calls in this secure cloud environment, one would need a Direct Routing calling plan through a government-approved provider like Atlantech Online.
