# List Phones

Retrieve a list of phones.

To fetch all results, run repeatedly with the `Offset` parameter as long as the result metadata has a `next_offset` value.

If no `Number` or `Extension` parameters are provided, the list will contain all phones.

Otherwise, the list will contain either a single phone (if a match was found), or no phones.

**Note**: This action requires the `Grant resource - Read` API permission.
