dears,
i have a legacy onprem pbx and im thinking of migrating it to microsoft teams. however, calling plans are not available in my region
1) if i use direct routing, can i get rid of my onprem pbx system? or it will be needed as direct routing will be a kind of a hybrid deployment?
2) can i transfer my numbers from my legacy pbx and use them in teams? or this feature is just available for calling plan
thank you in advance
