02 7506 8101 (0275068101): 3 community reports of automated robocalls with unintelligible audio and silent calls with no message.
Robocall and Silent Call Reports for 02 7506 8101
Three contributors have reported suspicious activity from 02 7506 8101 (also written as 0275068101), a local NSW service number. The reports indicate a pattern of automated calls delivering unintelligible or no audio, characteristic of robocall systems or potential scam infrastructure testing.
The number is allocated to Symbio Networks Pty Ltd as a local service in NSW. While the allocation details appear legitimate on the surface, the call behaviour reported by contributors suggests the number may be compromised or being used for unauthorised automated calling campaigns.
What Callers from 02 7506 8101 Do
One contributor answered a call from 02 7506 8101 and encountered an automated message with unintelligible audio described as "mumbo jumbo". The caller could not determine the purpose or identity of the caller, which is a common tactic in robocall probing or scam testing phases.
A second report from 02 7506 8101 describes a silent call with no message left. The contributor noted that the lack of any communication combined with the call pattern "feels like scam" activity. A third report captured the same silent call behaviour.
The absence of voicemails and the robotic nature of the contact attempts suggest this may be an automated system rather than a human operator, typical of illegitimate robocall networks.
Call Patterns and Timing
Reports of 02 7506 8101 span a 24-hour period from early morning to late morning. One silent call arrived at 04:08 in the early morning hours (4 November), while other calls came through during business hours on 5 November. The timing pattern and repeated contact attempts without coherent messaging indicate persistent automated calling behaviour.
Notably, when one contributor attempted to call back 0275068101 to identify the caller, no one answered. This non-responsive behaviour is typical of robocall operations, where inbound calls are not monitored or accepted.

WRITE A REVIEWFrequently Asked Questions
What is a robocall and why did 02 7506 8101 call me with unintelligible audio?
A robocall is an automated call system that dials numbers and delivers pre-recorded or dynamically generated messages. One contributor answered a call from 02 7506 8101 and heard only "mumbo jumbo" - unintelligible automated audio. This is often used by scammers to probe for active numbers, test fraud infrastructure, or deliver phishing messages. Robocalls from 0275068101 are illegal under Australian telemarketing laws unless the caller has prior express consent.
Why do silent calls from 02 7506 8101 happen with no message?
Silent calls from 02 7506 8101 (also 0275068101) where no voicemail is left indicate automated calling systems that disconnect if no human answers. Contributors reported receiving silent calls from this number with no follow-up message. These are often used by scam networks to identify working phone numbers for later targeted attacks, or by illegitimate robocall campaigns testing dialling infrastructure.
Should I call back 0275068101 if I miss a call from 02 7506 8101?
No. One contributor who called back 0275068101 found that no one answered, which is typical behaviour for robocall operations. Calling back unknown numbers, especially suspected robocalls or scam numbers, may confirm your number is active and lead to more frequent calls. Block 02 7506 8101 instead and report it to ACMA.
Is 02 7506 8101 a real business number or is it spoofed?
02 7506 8101 is allocated to Symbio Networks Pty Ltd, a legitimate NSW internet service provider. However, legitimate numbers are frequently spoofed by scammers and robocall operators. The behaviour reported by contributors - automated garbled audio, silent calls, and no response when called back - suggests the number may be spoofed or the account has been compromised. Contact Symbio Networks directly to verify if they initiated the calls.
What should I do if I keep receiving calls from 02 7506 8101?
Block 02 7506 8101 immediately using your phone's built-in blocking feature or your provider's call filtering service. Report the number to ACMA at acma.gov.au as a robocall violation. If calls continue after blocking, contact your phone provider to request additional investigation. You can also report the number on Reverseau to help other Australians in NSW identify the suspicious activity from 0275068101.
Can robocalls from 02 7506 8101 be a prelude to a scam?
Yes. Robocalls and silent calls like those reported from 02 7506 8101 are often used as initial probing by scam networks to identify active phone numbers. These numbers are then added to targeted scam campaigns (phishing, tax fraud, tech support scams). Contributors who received unintelligible audio or silent calls from 0275068101 should remain vigilant for follow-up calls from other numbers with specific scam messages, and report any escalation to Scamwatch.
