Hello? It's MS Teams calling

Now MS Teams Calling allows you to connect your Microsoft 365 phone system to the public phone network using Now’s network, so you can make calls to anywhere using the Microsoft Teams app. External calling can be enabled with no investment in equipment and your existing phone numbers can be ported to ensure customer continuity. Once you setup MS Teams calling your MS Teams users will be able to use their MS Teams app to make phone calls outside of your organisation.
