Microsoft Teams | How to use Skype phone number?

 Yes, Microsoft Teams can utilize Skype phone numbers, specifically Skype Numbers, in a few ways, but it requires a Teams Phone license and potentially a Calling Plan. Skype for Business, which is a separate product, is being retired and users are encouraged to migrate to Microsoft Teams. 

Here's a more detailed explanation:

• Skype Numbers in Teams:

  If you have a Skype Number (a phone number you purchased through Skype), you can port it to Microsoft Teams. This allows you to receive calls on that number within the Teams environment. 
• Teams Phone License:

  To use Skype Numbers or any other phone number for calls within Teams (including making calls to regular phones), you need a Teams Phone license. 
• Calling Plans:

  If you want to make calls from Teams to regular phones (landlines and mobile phones), you'll also need a Calling Plan, which is an add-on to the Teams Phone license. 
• Migration from Skype for Business:

  If you were using Skype for Business, you can port your Skype for Business number to Teams. Microsoft has provided resources and guidance to help users migrate their Skype for Business data and settings to Teams. 
• Skype Dial Pad in Teams Free:

  If you're using Microsoft Teams Free, you can access a Skype Dial Pad to make calls if you have active Skype Credit or a subscription.
