Based on the provided comments, it appears that the caller with the number +61272406155 is likely engaged in spam activities, as multiple users have reported receiving calls that were hung up immediately after answering. This behavior is consistent with automated dialing systems, which can be used to distribute unsolicited calls to a large number of recipients. The fact that the caller hangs up as soon as the call is answered suggests that the caller is not interested in engaging in a legitimate conversation, but rather may be attempting to verify active phone numbers or disrupt the recipient's daily activities.
The call was answered, but the other party hung up, suggesting a possible spam bot call.
The phone rang, and the caller hung up immediately after I answered. It appears to be a potential spam call from a bot.
