Changes in Normalization

Message Summary

Stopping normalization on number that starts with plus sign (+)

Normalization in Microsoft Teams was not designed to do normalization when the phone number starts with plus sign (+) as documented, but we’ve never enforced this in the Teams desktop or Web client. We are planning to enforce this in the future but for now we recommend avoiding this pattern. 

We are making this change to align with our Calling Service, other Teams services, Azure Communication Services SDKs, and other Microsoft services. Numbers that start with a plus sign (+) will not pass through any normalization rules. 

Translated numbers that do not start with a plus sign (+), will pass through normalization rules more than once. Please see : for more information

When this will happen:

Standard Release: We will begin rolling out mid-July and expect to complete by late August.

How this will affect your organization:

No one gets impacted immediately. We are letting you know to make you prepare for this change. If you have dial plan policies that has a pattern to match the phone number that starts with plus sign (+) or you rely on the number that starts with plus sign (+) to be translated, you have to adjust your dial plan policies. 

What you need to do to prepare:

There is no action needed to prepare for this change. You may want to notify your users about this change and update any relevant documentation as appropriate.
