Is 0440138171 a scam or just spam?
Based on the single report, 0440138171 appears to be spam rather than a scam. The contributor noted no interaction or deceptive claims - just an unanswered call with no voicemail. Spam is unwanted marketing or unsolicited calls, while scams actively attempt to defraud you.

Why did the caller from 04 4013 8171 not leave a message?
Callers from spam operations often don't leave messages because they're using automated systems to dial large contact lists quickly.

Legitimate callers almost always explain their purpose in voicemail.
