At present our primary focus in UK based businesses only. However, it is possible to deploy SIP Direct Routing for MS Team internationally with some important caveats. Calls between MS Teams users who are part of the same MS tenant will be on-net calls and therefore FOC. Calls from a MS Teams user based outside of the UK to a UK geographic or UK mobile number will use the available minutes bundles where applicable. Calls from a MS Team user based outside the UK calling a local number (a call from Germany to German number for example) will be charged as an international call.
