What Options are Available for Voice in Microsoft Teams? Part 1 of 3

Posted by lantelligence on Jun 21, 2020

Part one of a three-part series on What Options are Available for Adding Voice to Microsoft Teams. 

Now that you have deployed or started using Teams as a collaborative tool, either before or during the global pandemic, what do you need to do to add voice to your Teams deployment?

In the following parts of this three-part series, we will review some of the MSRP pricing (USD) to move to Teams with voice. 


Key Questions to Consider:

  • Is there a functionality on your existing Premise or Cloud based telephony solution you need to retain? 
  • If your users have a desktop telephony client, which one are they going to use going forward? 
  • Do you need the ability to call in the US or International as well? 
  • Are you moving more and more services to Office 365 and the level of licensing that you need? 
  • What level or licensing is your organization purchasing for those users who will be using Teams?


The answers to the above questions will help point out which is the better option if you plan on adding voice services to Teams. This is where LANtelligence would love to help map out a strategy and demonstrate the look of the end solution. Click the button below to contact us now.

Furthermore, here are the options you have when there is a requirement to add voice to Teams*: 

Phone System (Office 365) 

Phone System is Microsoft's technology for enabling call control and Private Branch Exchange (PBX) capabilities in the Office 365 cloud with Microsoft Teams.

Phone System allows you to replace your existing on-premises PBX system with a set of features delivered from Microsoft 365 or Office 365 that is tightly integrated into your cloud experience.

To connect Phone System to the Public Switched Telephone Network (PSTN), you can choose
Microsoft Microsoft’s Calling Plan or your own telephony carrier and/or current PBX


Connection to Public Switched Telephone Network (PSTN) 

Phone System can be connected to the PSTN in one of two ways: 

    1. Calling Plan (Office 365)

      Purchase a Microsoft Calling Plan (domestic or domestic and international).
      Microsoft Calling Plan is an all-in-the-cloud solution with Microsoft as your PSTN

    2. Connect your own telephony carrier

      Use your existing telephony infrastructure for on-premises PSTN connectivity. With Calling Plan, Microsoft is your PSTN carrier.

      For your Teams users, you can connect your on-premises telephony infrastructure to Phone System by using Direct Routing.
