The team is working to address issues with call controls that occur for users running both Teams and Skype for Business. We will let you know when there is more to share.
Thank you for your feedback! The team has reviewed this request and has added it to our backlog for both Standard (Public) to Private and Private to Standard (Public) channel conversion. We will share an update as soon as it’s available.
We are happy to inform you that you are able to join meetings by choosing “Call me” from the join dropdown on iOS & Android. To use this feature, you need to provide a phone number where you can receive a phone call. If the call is accepted, your meeting audio will switch to the cellular connection. Your personal and work phone numbers, if added to your account, will be available for selection automatically.
The team is working to release this feature for Desktop. I don’t have dates to share at this time, but will keep you posted.
