Frequent calls from unknown numbers like this often signal nuisance or potential scam attempts, especially when callbacks lead to a full mailbox. This tactic avoids direct contact while probing for active lines. In quiet evenings or busy workdays, these interruptions can be frustrating and time-wasting. Block the number immediately on your phone to stop the harassment. Enable call screening features if available, and report it to your carrier or authorities like the FCC for patterns of abuse. Avoid returning calls to prevent engaging with possible fraudsters—silence is your best defense here.
Frequent calls from this line lead to a recording that only says the mailbox is full when you try to return the call—quite odd.
