Here’s a handy list of URLS Teams Handsets access.
This list was captured using a Pi-hole, from the moment the handset was turned on, registering with Intune and Azure AD, and signing in to Teams. Making calls and joining a meeting are also included.
Note: The list only includes URLs and does not include IP addresses that are listed here: Office 365 URLs and IP address ranges – Microsoft 365 Enterprise | Microsoft Docs
