Provision a Microsoft Teams Calling Plan phone number for the Dynamics 365 Customer Service / Contact Center voice channel — end to end, from prerequisites to the number appearing in the Copilot Service admin centre. Use when "Sync from Teams" finds nothing, a Teams phone number is missing from the Phone Numbers list, outbound calls fail with 404 / sub-code 580406, or you need the full resource-account + license + Entra-app provisioning sequence for a Teams number in Contact Center.
