Suspicious Callback Activity from 02 4277 0180

Four contributors have reported calls from 02 4277 0180 (also written as 0242770180), a local NSW number allocated to Symbio Networks. What stands out across these reports is the pattern of one-way calling: the number calls in but doesn't leave a message, and when contributors attempt to call back, they encounter technical issues or find the number appears invalid.

This callback pattern is characteristic of either automated systems testing numbers for active use, or callers masking their true identity. One contributor who tried to return the call to 0242770180 received a system message indicating the number was not in service, despite clearly receiving the incoming call from it.

What Contributors Experienced with 02 4277 0180

The four reports about 02 4277 0180 show consistent behaviour:

• Missed calls with no voicemail left
• No caller identification message or greeting
• Callback attempts to 0242770180 result in "check the number first" errors or "not in service" notifications
• One contributor noted the caller ID showed "Kiama" location data, but the number itself appears dormant when called back

These characteristics suggest the calls may be generated by automated systems or spoofed using the 02 4277 0180 number as a mask. Legitimate businesses typically leave a message or ring with caller identification information.
