In Auckland's bustling evenings, calls from unfamiliar 09 numbers often spark caution, especially when silence greets your hello. This pattern screams spam tactics, where predators test active lines for later harassment or scams. The lack of response is a classic robocall ploy to confirm your number's live status. Hang up immediately if it happens again—don't engage. Block the number via your phone settings or carrier app to cut off future nuisances. Report to New Zealand's Do Not Call Register or anti-spam authorities for broader protection. Stay vigilant; these silent probes can escalate to aggressive pitches or worse.
The caller seemed dubious since I rarely receive 09 numbers; after answering silently and hearing no response, it appears to be a spam or predatory line
