Source note · CUCM to Teams Phone migration
If Microsoft provides the PSTN access and phone numbers, the user additionally requires a Microsoft Calling Plan licence; if a non-Microsoft PSTN operator is used, Microsoft requires no other licensing because the PSTN costs are incurred from that operator.
Checked 2026-09-16
If you elect to use a PSTN operator other than Microsoft, then Microsoft doesn't require other licensing because the PSTN costs are incurred from your preferred operator.
