 **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 can't 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 can't guarantee that the call reaches to your Toll-Free number.
