The Number Spinner supports flexible CLI selection strategies tailored to each user’s needs. The random strategy picks any number from the available list, ensuring varied and unpredictable caller IDs. The prefix-matching strategy chooses a CLI with a matching destination number prefix, enhancing regional alignment and familiarity. When multiple matches exist, a configurable approach—like round-robin or least-used selection—can determine the optimal number. These strategies help customize caller ID behaviour, improving call response rates and user control.
