  @JoGu1802 It was because Optus no longer supported the iPhone 5 on its app that I upgraded. Because it’s DAMN hard to use the app to prepay for your phone when the app doesn’t… support your phone…

  It's not like mainstream media dont know about ANY of this. 👇👇 In September 2017, the federal government announced a $50 million investment over seven years in the Cyber Security Cooperative Research Centre (CSCRC). The CEO was Rachael Falk. She led the independent review into the Optus and Medibank cyber breaches. She was appointed by the Minister for Home Affairs to the Expert Advisory Board for Australia’s 2023-2030 Cyber Security Strategy. In February 2025, Falk left the CSCRC to become a partner at Ashurst Risk Advisory—a return to the firm where she had worked as a lawyer in 1998. The CSCRC was not just a research centre. It was a revolving door—a place where a connected insider could build a network, then cash in.

  @MichaelRuyg yep, when they built the NBN fixed wireless tower, that carries optus and vodafone as well, it had a backup generator. then the tower got "upgraded" with 6 months of regular outages and then next power outage we discovered the backup generator and the ability to call 000 was gone

  @Optus The reason I ask is my account is now overdue by 8 days, I'm able to pay the bill in 2 days in full however when asking for help or letting optus know of concerns with overdue accounts and financial difficulties the automatic payment system set up on this account restricts the help i can ask for online

  Ask Grok: Can ISPs block VOIP? Yes, ISPs can block Voice over IP (VoIP) traffic at their network level, and many do so in practice. This is technically feasible using tools like port blocking, deep packet inspection (DPI), and other traffic management techniques. How ISPs Block VoIP ISPs control the core network infrastructure, so they can inspect and filter traffic before it reaches customers. Common methods include: Port-based blocking**: Traditional VoIP often uses specific ports like UDP 5060/5061 for SIP (signaling) and a range of ports (e.g., 10000–20000) for RTP (media/voice). ISPs can simply drop traffic on these ports. Deep Packet Inspection (DPI)**: This examines not just headers but packet contents, signatures, packet sizes, timing, and protocol behavior to identify VoIP even if it uses non-standard ports or obfuscation. DPI can dynamically detect and block SIP, RTP, or app-specific patterns (e.g., Skype, WhatsApp calls). IP address or domain blacklisting**: Blocking known servers of VoIP providers. Protocol anomaly detection or traffic shaping**: Dropping or throttling UDP-heavy, low-latency streams typical of voice calls. Real-World Examples Certain countries and carriers (e.g., in the Middle East, Morocco, Philippines, or places with state telecom monopolies) block VoIP to protect traditional phone revenue or for regulatory reasons. Mobile providers like Optus 4G or others have blocked SIP traffic. Corporate/school networks or bandwidth-limited ISPs sometimes block or deprioritize VoIP to conserve resources. China has historically blocked VoIP, though workarounds emerged over time. Limitations and Challenges for Complete Blocking Encryption and obfuscation**: Modern VoIP (e.g., over WebRTC, HTTPS, or apps like Signal/WhatsApp) is harder to detect reliably. DPI isn't foolproof against randomized ports, variable packet patterns, or VPN-like wrapping. VPNs and tunnels**: Users can often bypass blocks by routing traffic through a VPN, which encrypts and hides the VoIP signature. Evasion techniques**: Providers and users adapt with port hopping, STUN/TURN servers, or proxies. False positives**: Overly aggressive blocking can disrupt other UDP-based services (gaming, video streaming). Complete, unbreakable blocking is difficult long-term without also harming general internet performance, but partial or effective blocking for most users is very achievable. Why ISPs Do This Reasons include protecting legacy telephony revenue, complying with regulations, managing bandwidth, reducing congestion, or enforcing content policies. In summary, yes—ISPs have both the capability and precedent for blocking VoIP, primarily via DPI and port controls, though motivated users can often circumvent it. If you're dealing with a specific ISP or scenario, details could help narrow down options. TCP/IP allows spam filters at the node level. This is one small example. TCP/IP remains neutral and ethical.

  @Candour100 @blu_boys @Optus Yeah my husband had to switch to the Telstra network because of remote work. Boost was his choice.

  @tiny_watermelon @Optus I just realised I didn't get an alert today either, while I was sleeping. Considering I'm a disabled pensioner that's a little concerning. In the days of landline phones, I was on a high-priority service. Maybe it's because I don't have a smartphone ? Goodness knows.
