As of now, there isn’t a supported way to simply “transfer” a Skype number that’s linked to a personal Skype account directly over to Microsoft Teams. Skype numbers and Teams phone numbers are treated differently within Microsoft’s ecosystem. Here’s a bit more detail:
• Skype numbers are provided as an add‑on service for personal or consumer Skype accounts. They’re managed separately from Microsoft’s enterprise Phone System (used in Teams).
• Microsoft Teams’ calling functionality (whether you’re using a Calling Plan, Direct Routing, or another telephony solution) requires numbers to be provisioned or ported as part of your organization’s Phone System setup. The phone numbers used in Teams typically come from carriers or are ported from eligible external providers—not directly from Skype.
