How it works
Caller-ID presentation works when the network supplies the identity and the called endpoint is allowed to display it. 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
An employee sees the calling number on a phone display when its presentation is allowed.
What to consider
Before deployment, verify geographical availability, permitted number formats, tariffs, caller-ID restrictions and both inbound and outbound calling behaviour.
