Business Phone System
The best Business Phone System for SMBs and nonprofits
Choosing the right business phone system is essential for small businesses and nonprofits, offering flexibility, reliability, and a professional edge without overwhelming costs. You’ll likely fall into one of two categories:
Already using a phone system?
If you’re already using a traditional or VoIP-based business phone system, switching to a modern cloud business phone system is straightforward. The interface is intuitive, and features like call forwarding, voicemail-to-email, and mobile access make daily operations smoother and more efficient.
Not using a business phone system yet?
If you’re still relying on personal phones or basic landlines, adopting a cloud-based business phone system can transform the way you communicate. You’ll gain access to an easy-to-use business phone system with tools for handling calls, team collaboration, and even video conferencing, all tailored to support growing teams and tight budgets.
Lowered costs
Using a cloud-based business phone system helps save on upfront costs like hardware procurement and maintenance, as well as recurring expenses like licensing fees. Per-user costs start at just $20 per month.
Practical business features
Teams Phone includes features such as auto-attendant, custom call queues, call routing, voicemail and transcribing, and more—making it a powerful business phone system for modern organizations.
Useful analytics
Microsoft Teams Phone has a built-in visual analytics dashboard that helps identify bottlenecks in your business phone system and improve efficiency for specific employees or the entire company.
Easily scalable
When hiring a new employee, scaling your business phone system is quick and easy. Setting up a new phone doesn't require purchasing hardware or any new wiring.
User-friendly software
Using Teams as a base software for team collaboration and calls reduces the complexity of adopting a new business phone system and avoids confusing employees with challenging interfaces.
Seamless remote work
A cloud-based business phone system like Teams Phone supports seamless remote work. Employees can make and receive calls, access voicemails, and collaborate from anywhere, ensuring consistent communication whether at home, in the office, or on the go.

Frequently Asked Business Phone System Questions
Yes, you can keep your existing numbers when you move to Microsoft Teams. We will port your numbers to Teams, and Microsoft will become your new service provider.
You have several options:
- If you prefer a traditional physical office phone, we can set you up with a Teams compatible VoIP phone or headset to give you better mobility.
- You can simply use your computer/laptop/cell phone with the Teams app installed. Either use your cell phone like you would for personal calls (with the separate business number) or your computer with a microphone and headset.
The specific system depends on your business needs, budget, and other factors that we take into consideration during your free assessment.
We ask questions about how your business works and help you make an informed decision that you are happy with. But to answer the question in general — we prefer Teams Phone because it is part of the Microsoft ecosystem and really helps streamline work without the steep learning curve.
Both platforms offer excellent call quality with a stable internet connection. Teams Phone leverages Microsoft’s global infrastructure, while 3CX delivers HD voice and smart call routing for clear, reliable communication.
