Teams calling with External Users

[Keith_Chan912]

we are using Teams to communicate with our Vendor, and we added their contact into Azure AD as guest user. it is works for a long time.

somehow, they reported all of them missing the call button. we tried , we can't make a conference with them by Teams, but message is ok.

Has anyone seen this before?

@Keith_Chan912 Do you have the same for all guest users?

The only thing that I know controls private calls for guest is the guest settings in Teams Admin Center, is that enabled?

@Linus Cansbythis option is off.

i enabled it and let's see if it works or not.

thank for your help! Bro

The default setting for this is on, so you should maybe check why someone turned it off.
