How it works
The number owner usually pays for incoming calls under carrier terms; free access for callers may depend on network and country. Telephone numbering depends on national rules, carrier capabilities and the selected calling route. Customers benefit from consistent dialling formats and reliable number reachability.
Business example
A business offers customers a toll-free support line subject to operator coverage and tariff rules.
What to consider
Before deployment, verify geographical availability, permitted number formats, tariffs, caller-ID restrictions and both inbound and outbound calling behaviour.
