Question
What are the calling restrictions for toll-free numbers?
Answer
Inbound
Toll-free numbers should be used for domestic inbound voice calls only. If you try to call a toll-free number from a phone number outside that number's country, your call might not go through because these numbers are usually set up to work only within their own country.
Outbound
Outbound calls aren't supported from toll-free numbers, this also applies to numbers added as external numbers.
Since callback and overflow features rely on making outbound calls and toll-free numbers can't do that, you'll want to turn those features off.
Excepcions
Toll-free numbers from the United States, Canada, and Japan can make outbound calls to numbers from the same country. However, they cannot call international numbers.
