Microsoft Teams Network Requirements
If you are having network issues or you just are using the Microsoft Teams phone system for the first time, then it is important to review your network security to ensure it's allowing Microsoft to get to you with no difficulties.
Below is the link to the Microsoft Network Assessment tool. This
can be run on any PC, and will tell you if there are any difficulties
communicating with Microsoft.
Below is the site link for the IP ranges which you want to accept through for Microsoft Teams servers.
