Silent Call Reports for 03 7305 2981
One contributor has reported receiving repeated silent calls from 03 7305 2981 (also written as 0373052981). The calls follow a consistent pattern: the line connects but the caller remains silent, then disconnects after a few seconds. This behaviour is characteristic of silent calls, which can indicate robocalling systems, callback scams, or automated dialling operations testing active numbers.
The number is allocated as a local service through Symbio Networks Pty Ltd in Victoria, which should theoretically be a legitimate Victorian business line. However, the silent call pattern suggests the number may have been compromised or is being used for automated calling campaigns.
