These calls are classic spam‑robocall behavior, hammering recipients with multiple unanswered rings and never leaving a voicemail. The pattern of daily 5‑6 calls from varied area codes is a red flag for automated dialing lists. Block the number on your device, report it to the FCC, and consider using a call‑screening service. If you receive a text asking "who is this?" and get no response, treat it as suspicious and avoid replying. Stay vigilant and keep your caller ID settings tight to reduce exposure.
Daily calls, sometimes 5 or 6 times a day, are made from various US locations, with no messages left, which is disturbing, especially during work hours.
