Robocall and Silent Call Reports for 07 2143 5645
Three contributors have reported suspicious activity from 07 2143 5645 (also written as 0721435645), a Queensland local service number allocated to Symbio Networks Pty Ltd. Two separate reports describe silent calls characterised by an audible connection click followed by complete silence, with callers indicating an overseas origin. One contributor also flagged a telecom-related inquiry where the caller requested to speak with a manager or random worker, with records linking the number to Trilogy Care in Brisbane.
The pattern of repeated silent calls from 0721435645 suggests automated dialling activity typical of robocall campaigns. Contributors who answered the call from 07 2143 5645 experienced immediate silence rather than a human greeting, a common indicator of mass-call systems that connect only when a call is answered.
What Callers from 07 2143 5645 Experience
Two reports about 07 2143 5645 describe identical experiences: the call connects with an audible click sound, then silence persists on the line. Both contributors received multiple calls over a short period, suggesting systematic dialling rather than accidental misdials. One contributor noted the distinctive overseas quality to the connection, including the characteristic delay and background noise associated with international calls.
A third report involving 0721435645 documented a different interaction where a human caller requested connection to a manager, and when declined, asked for a random worker by name. This pattern differs from typical silent robocalls but raises questions about the purpose of the call attempt, with the contributor noting the number's association with a Brisbane-based organisation.
Report Patterns and Timing
All three reports about 07 2143 5645 came through answered calls rather than missed calls, indicating the number's dialling system successfully connected with recipients. Two reports were submitted within roughly two weeks of each other (26 February and 7 March), while the telecom inquiry was logged on 19 February. The consistency of silent-call reports suggests ongoing robocall activity from this number rather than isolated incidents.
Contributors experienced calls at various times, with one report documenting calls received during early morning hours (03:50 UTC), typical of automated systems that operate continuously across time zones. The repeated nature of calls from 0721435645 mentioned by contributors indicates the number remains active in placing multiple attempts to the same recipients.
What to Do If You Receive a Call from 07 2143 5645
If 07 2143 5645 calls you:
- Do not: Stay on the line during silence, speak personal information, or press any keys in response to prompts
- Do: Hang up immediately, block the number on your phone, and do not return the call
- Consider: If the caller eventually connects, ask them to identify their organisation and purpose before engaging further
Robocalls and silent calls from 0721435645 should not receive callback attempts, as connection-click patterns often indicate systems designed to identify active phone numbers for future targeting. Blocking the number prevents repeated attempts and reduces your exposure to automated dialling campaigns.

WRITE A REVIEWFrequently Asked Questions
Why do I hear a connection click then silence when 07 2143 5645 calls?
The connection click followed by silence is characteristic of robocall systems that use automated dialling. When 0721435645 connects to your number, the system detects the answered call but doesn't immediately route you to a live agent or recorded message. This pattern helps robocall operators identify working phone numbers for future targeting. Hanging up immediately and blocking 07 2143 5645 prevents further attempts.
Is 0721435645 calling from overseas?
Two contributors who answered calls from 07 2143 5645 reported hearing overseas connection characteristics, including distinctive delay and background noise. However, the number itself is allocated as a Queensland local service by Symbio Networks Pty Ltd. The overseas quality may indicate the call is being routed through international gateways or originated from offshore despite using an Australian number. This technique is common in international robocall campaigns.
What does the caller from 07 2143 5645 want if they actually speak?
One report about 0721435645 documented a human caller requesting to speak with a manager or asking for a random worker. This differs from the typical silent-call pattern and suggests the number may be used for both robocall campaigns and direct inquiry attempts. Contributors should not provide employee names, transfer information, or any details when 07 2143 5645 calls, as the intent remains unclear.
Should I call 07 2143 5645 back?
No. Do not return a call to 0721435645. Returning the call confirms to the robocall system that your number is active and monitored, likely increasing the frequency of future calls from this number and similar campaigns. If you're concerned about a legitimate inquiry, use official channels to contact organisations directly rather than calling back from an unknown number like 07 2143 5645.
Is 0721435645 connected to Trilogy Care?
One contributor noted the number was linked to Trilogy Care in Brisbane, based on their own research or caller identification. However, this does not confirm Trilogy Care initiated the call. The number 07 2143 5645 is allocated to Symbio Networks Pty Ltd, a telecommunications provider, meaning the actual caller could be using this service without representing the organisation. Verify directly with Trilogy Care through official contact details if you're concerned about a specific inquiry.
What should I do if I keep receiving calls from 07 2143 5645?
Block the number immediately in your phone's settings to prevent further connection attempts. Report the calls to ACMA at acma.gov.au and Scamwatch at scamwatch.gov.au, providing the date and time of each call from 0721435645. If you have a landline, contact your telephone provider about implementing additional call filtering. Contributing your report to Reverseau helps other Australians recognise 07 2143 5645 and take preventive action.
