Firewall configuration of calling applications for Teams users

Azure Communication Services allow you to build custom Teams calling experiences.

You can use the Calling Software development kit (SDK) to customize experiences. Use your Administrator account to configure your firewall based on Communication Services and Microsoft Teams guidelines. Communication Services requirements are for control plane and Teams requirements are for Calling.

If you use an independent software vendor (ISV) for authentication, use instructions from that vendor and not from Communication Services.
