 **Outbound calling with Toll-Free numbers**
 
-Microsoft provides Toll-Free telephone numbers that have outbound calling capabilities, but it's important to note that this feature is only provided on a "best-effort" basis. In some countries/regions, toll-free numbers are considered as an "inbound only" service from regulatory perspective. This means, that in some scenarios, the receiving carrier may not allow incoming calls from toll-free telephone numbers. Since Microsoft and our carrier-partners don't have control over other carrier networks, we can't guarantee that outbound calls will reach all possible destinations.

 **Inbound calls to Toll-Free numbers**
 
-All of our Toll-Free numbers have inbound calling capability, but do note that inbound calls to your Toll-Free numbers are only guaranteed to work if both the Toll-Free number and the caller's phone number are from the same country. If a call to your Toll-Free number originates outside the Toll-Free number country, we cannot guarantee the delivery of the call. In most cases, international reachability on our Toll-Free numbers is supported, but there can be certain international carrier and country combinations where we cannot guarantee that the call reaches to your Toll-Free number.
