M365 Changelog: (Updated) SIP / H323 dialing from MTR-W to a VTC

MC543860 – Updated June 8, 2023: Microsoft has updated the rollout timeline below. Thank you for your patience.

Starting early June, you can configure your Teams Rooms on Windows with a Pro license (MTR-W Pro) to place and receive one-to-one calls from the room to a SIP/ H323 endpoint and vice versa. If you want to enable this calling feature, you must work with a CVI provider to enable the service.

This message is associated with Microsoft 365 Roadmap ID 95263

When this will happen:

Standard Release: Microsoft will begin rolling out in mid-June (previously early June) and expect to complete by late June (previously mid-June).

How this will affect your organization:

There is no increased risk for you; the feature will be released disabled by default.

Only if you configure your MTR-W Pro by running the right PowerShell commands that enable the feature and if you have contacted a CVI provider that offers this service, your MTR-W Pro will be able to place and/or receive calls to and from SIP/H323 endpoints. These endpoints can be internal (within your organization) or external (outside your organization)

What you need to do to prepare:

If you do nothing, no change is needed and no impact for you. Your MTR-W Pro will continue working as today.

If you want to enable the feature, you must run the PowerShell commands to set up the MTR-W Pro and explicitly configure and enable if you want to allow the room to receive internal (from within your organization) or external (from outside your organization) calls from SIP / H323 endpoints.

How to disable the MTR-W Pro rooms you enabled:

If you want to disable an MTR-W Pro that you have enabled, you just need to run the same PowerShell command that you ran before and explicitly disable the feature.
