Repeated Calls from 03 9961 2118
Eight contributors have reported problematic activity from 03 9961 2118 (also written as 0399612118), with a clear pattern of aggressive repeated calling. The most distinctive finding is the caller's use of number variation tactics, changing a single digit across multiple attempts to bypass blocks. This suggests a coordinated campaign rather than a one-off call.
The number is allocated to a local service provider (Symbio Networks Pty Ltd) in Victoria, but multiple reports describe the calls as spam originating from related numbers. One contributor noted receiving three separate spam calls from variations of 0399612118, each with one digit changed, attempting to circumvent call blocks.
What Callers from 03 9961 2118 Do
Callers from 03 9961 2118 employ several specific tactics. Multiple contributors report receiving calls with no one on the line when answered - one contributor simply noted they answered and "didn't say anything." Others describe the calls being screened automatically by iPhone's spam filter, with no voicemail messages left.
One contributor received an SMS after a call from someone claiming to work for a plumbing and roofing business, signed "Jordan." This suggests at least some calls are attempting to solicit business or generate leads. The concerning aspect is the intentional number variation strategy. A contributor reported receiving calls every 15 minutes from "random numbers," later identified as variations of 0399612118 with single digits changed - this is a known evasion tactic to defeat call blocking.
Call Patterns and Timing
The reports span from late August through mid-September, showing sustained activity over several weeks. Contributors describe the frequency as intensive: "rings daily with no message," "back to back calls," and one report of calls arriving "every 15 minutes." The calling pattern is consistent across multiple contributors, suggesting a coordinated campaign rather than isolated incidents.
Most reports involve missed calls that contributors did not answer, with Apple's spam detection flagging 03 9961 2118 and related numbers. When contributors attempt to return the call, they report callback failures, indicating the number may not accept incoming calls or the service is one-way.

WRITE A REVIEWFrequently Asked Questions
Why does 03 9961 2118 keep calling even though I blocked it?
Multiple contributors report that callers from 0399612118 use number variation tactics, changing one digit at a time to bypass call blocks. When you block 03 9961 2118, expect calls from similar-looking numbers (e.g., 03 9961 2119, 03 9961 2117). This is an evasion technique used by spam campaigns. You will need to block each variant as it appears, or ask your service provider about blocking number patterns. iPhones with spam detection enabled will help automatically filter these repeated variants.
Is 0399612118 a legitimate business number?
The number is allocated to a local service provider, but eight contributors have flagged it for spam and nuisance calling activity. One contributor received an SMS claiming to be from someone named Jordan at a plumbing and roofing business, but without independent verification. Contributors should not assume legitimacy based on the allocation - multiple spam and scam operations use legitimate service allocations. If a business claims to be contacting you from 03 9961 2118, verify by contacting the business directly using a number from their official website.
What happens if I answer a call from 03 9961 2118?
Based on contributor reports, if you answer 0399612118, the most likely outcome is silence or no one responding. Several contributors who answered reported the caller said nothing. One contributor described the call simply as 'spam' with no message. Do not engage - if no one speaks within a few seconds, hang up immediately and add the number to your block list.
Why do I get a failed callback when I try to call back 03 9961 2118?
Multiple contributors report that attempts to return calls to 0399612118 fail. This indicates the number is likely set up for outgoing calls only and may not accept incoming connections. This is a common tactic in spam and scam operations - the number is configured to call out but not receive calls, making it harder to verify or respond to the campaign.
Should I report 03 9961 2118 to my phone provider?
Yes. Contact your service provider and report 0399612118 and any variants you've received calls from. Providers like Symbio Networks (the allocated provider) and your own carrier can investigate and block numbers at the network level. You can also report to ACMA at acma.gov.au or via SMS to 0429 999 888 with details of the calls.
Is this a scam or just spam from 03 9961 2118?
Contributors classify activity from 0399612118 as nuisance calls and spam rather than confirmed scam attempts. The pattern shows aggressive repeated calling (sometimes every 15 minutes), number variation to bypass blocks, silent calls, and at least one unsolicited SMS. While not all reports describe a financial or personal scam attempt, the aggressive repeated contact and evasion tactics are red flags. Treat it as unwanted contact and block it.
