To get the best video and calling experience on Microsoft you need an internet connection that can support Microsoft Teams.

You also want to make sure that your computer can reach the Microsoft 365 server.

To follow these steps, you need to have a license with one of the following subscriptions:

  • Microsoft 365 Business Basic
  • Microsoft 365 Business Standard
  • Office 365 E1
  • Office 365 E3
  • Office 365 F1
  • Microsoft 365 A1
  • Microsoft 365 A3
  • Microsoft 365 E3
  • Microsoft 365 Business

Microsoft recommends that you don't use more than 30 percent of your total internet connection speed.

For example, if your Internet connection is 60 Mbps, Teams and Business Voice should use no more than 18 Mbps.

Use this equation to determine your minimum Internet connection speed: <highlighted number> / 0.3.

With the number that's highlighted in the preceding image, the calculation is 4.6875 / 0.3 = 15.6. In this case, the Internet connection speed should be at least 15.6 Mbps.

If Teams and Business Voice will use more than 30 percent of your total Internet connection speed, the highlighted number will appear red. In that case, you may need to upgrade your Internet connection.

Use Microsoft Network Planner Tool to figure out what your highlighted number use.

Follow these steps:

  1. In a browser, go to https://admin.teams.microsoft.com.
  2. Sign in by using an account that has Global Administrator permissions. The account that you used to sign up for Office 365 has these permissions.
  3. Open Planning and select Network planner.
  4. Under Network plans, select Add. Enter a name for your plan, and then select Apply.

Make sure the computers and devices on your network can reach Microsoft 365

Computers and devices that use Business Voice must use specific network ports to communicate with Microsoft 365 servers. These ports are essentially doors through which devices talk to each other over a network or the Internet. Your firewall needs to allow devices on your network to reach Microsoft 365 through the following outbound network ports:

  • TCP ports 80 and 443
  • UDP ports 3478, 3479, 3480, and 3481

The easiest way to check whether your firewall allows communication on these network ports is to make a test call in Teams:

  1. Go to https://aka.ms/getteams on a computer on your network and install Teams. Make sure that the computer has speakers and a microphone.
  2. Open Teams and sign in by using a Microsoft 365 account.
  3. In Teams, select your profile picture, and then go to Settings > Devices.
  4. Under Audio devices, select Make a test call.
  5. Follow the steps to leave a message and have it played back to you.
  6. If the call connects and you hear your message, your firewall is set up correctly.
  7. If the call connects, but you can't hear the instructions or your message, make sure that your speakers and microphone are set up correctly, and then try again.
  8. If the call doesn't connect or it connects but you can't hear your message, you might need to update your firewall to allow access to the required network ports. Check your firewall's documentation, or contact an IT specialist for help.

If you're an IT professional and want more information about how to prepare larger or more complex networks to support Business Voice, see Evaluate my environment.
