Direct routing service is adding capacity across regions and that capacity falls into already published Teams IP ranges and domains. Please make sure that all published Teams specific endpoints are permitted for your Direct Routing scenarios.
Affected Workloads
- Microsoft Teams
When this will happen
Beginning in late June and expect to complete by early July.
How this will affect your organization
As part of Teams Direct Routing expansion and service improvement we have deployed new instances of Direct Routing infrastructure in Japan. If you have Teams Direct Routing enabled, before this change takes effect, you need to make sure that:
- Your Session Border Controllers are configured correctly
- That all IPs from Plan Direct Routing – Microsoft 365, Office 365, and Office 365 GCC environments are added to your IP Access Control Lists (ACLs)
- You have opened ports for all these IP addresses in your firewall to allow incoming and outgoing traffic to and from the addresses for signaling. For more information please see Plan Direct Routing
Users may no longer be able to make calls via Direct Routing, when this change is implemented if proper configuration is not applied and not all steps are followed.
What you need to do to prepare
Follow the guidance at Plan Direct Routing and add all Direct Routing endpoints to your IP Access Control Lists (ACLs) and open all required ports
