Why Microsoft Teams is the best phone system for your business

Why Microsoft Teams is the best phone system for your business

Since its launch, Microsoft Teams has become the fastest growing app in Microsoft history, with over 330,000 companies worldwide using it!

As we continue to work from home, pressure has increased on all areas of IT within businesses, and communication seems to be getting the short end of the stick. Many businesses are simply aiming to reconfigure the classic “on-premise” approach to try and make things work for employees who are working from home. For many, this has taken shape in diverting calls back out to a mobile phone resulting in tying up two trunks or trying to deploy a softphone solution the business has never tested, which is not as simple as it looks!

We’ve seen this across nearly every business with a physical phone system in place for years.  Some modern phone systems do have some flexibility to try and work around this. Still, many older systems impact business because the systems are inflexible and unable to function effectively.  In stark contrast to a physical phone system, Microsoft Teams is the online platform that many businesses have already adopted for; video conferencing, instant messaging and group communication.

How does Microsoft Teams work?

We have seen a mass shift in the market, with many organisations transitioning their voice calls into Microsoft Teams. The approach to this is to use the Microsoft Cloud PBX system. Microsoft Cloud PBX is a technology that was built on the success of Skype For Business. It leverages local break out for calls across Microsoft global Azure network, only transitioning to SIP and then traditional calling technology once it leaves the global infrastructure that Microsoft own.

Key Features of Teams Voice include: 

  • Phone System (formerly known as Cloud PBX) with Microsoft Calling Plans or Direct Routing for PSTN services 
  • Users can receive and transfer calls using mobiles, desk telephone hardware or software phones on their devices. These devices can be mobile IOS or Android, and the desktop client supports Windows and Mac. 
  • Domestic Calling – Calls made from your own country/region are free. International plans and toll-free dialling are also available. 
  • Audio Conferencing – Teams Voice allows you to host a conference call with people who may not use teams or don’t have an internet connection 

Each user will have access to direct dial numbers and participate in call groups and the auto attendant. To add to this, you are entitled to multiple calling functions, for example:  

  • Call History 
  • Call Forwarding 
  • Voice messaging 
  • Simultaneous calls
  • Dial by name directory 
  • Presence (shows other team members when you’re on a call) ​

Each business has different requirements and needs. Microsoft Teams can be tailored to you and your company, ensuring you are not paying for anything unnecessary.


When you adopt Microsoft Teams Voice, you can fully integrate with other Team features such as messaging, meetings, emails, and documents, enabling a more fluid and efficient working experience. 

Why should I use Microsoft Teams for my business communications?

Many will tell you not to have all your eggs in one basket, email, instant messaging, phone, VC, but having all these integrated into one place makes management much smoother and reduces the load on your IT team. Add to that, only paying one licence fee per user instead of multiple for different applications.

What happens if your internet connection goes down, your phone system goes offline… Not with teams. If users have the Teams app installed and logged in on mobile devices, they can switch to mobile data in the interim and still be available. Ideal when you have a distributed team and people on the road.
