Why Scammers Use Silent Calls
Silent calls serve as a verification tool. When you answer, the caller's system records that your line is active. If you hang up without responding or if the call goes to voicemail, your number may be flagged as monitored or unresponsive. Scammers use this information to refine their targeting lists or to avoid calling numbers that are likely to report them.
The brief pause reported from 02 8004 9617 before disconnection is typical of automated systems that detect a live answer and then decide whether to transfer the call to a live operator or disconnect. This behaviour does not necessarily mean harm will follow immediately, but it indicates your number has been identified as active.
