MS Teams roaming
Hi How does MS teams server know which country user is currently in when receiving a call on a landline number. For example, the user has UK landline number on teams account and if the user receives a call (while abroad), the caller get a ringing tone that is from abroad instead of normal UK ringtone. I suspect when the user register while abroad the servers recognise the IP of user which is not from UK or the the fact the the user registers to a non-UK Teams server because of DNS but I want to know precisely how it works please. Thanks
