I saw an article in a google search that says you can apply an extension number to a user without needing a voice license. The article did not explain how it could be done. I have run the typical powershell commands but they all fail, due to user not being licensed. Does anyone know if this can be done?
'Extension Number' doesn't really have any meeting in Teams voice, everything is E164 anyway. Anyone in a call that involves a PSTN number needs a E5 or Teams Phone System license, other than conference calls.
