  @FelixCLC_ What's been the biggest problem you've faced using Optus with hardware design ?

  @alex_prompter The problem is Fable isn't actually worth using. Optus ultra is a better all rounder

  @Optus @itsallTag So I don’t get I got 5G on my phone when the test came through even though that there is currently an outouge on my closest network tower and I am only receiving 1 bar of 4G because of the outage of that area tower so it doesn’t make sense to me towers also need to be fixed irl

  Why does @Optus now require a direct debit to be setup if you want to change your internet plan? I have had post paid plans with Optus for years and never an issue but now have been told it is the only way😡

  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.

  @Telstra What a disgrace that each Telstra customer has to individually apply for compensation for the outages last week. Really shows what you think of your customers. Just provide free data like Optus did you scabs. Pathetic 😡 #telstra #telstraoutage

  Halftime at Optus. That second quarter was, despite the inaccurate set shots, actually a lot better than the first. But we're still down by 7 points, so it's time for the Lions to regroup and go again in the third term. Hopefully the Eagles will finally lose their legs by then. #AFLEaglesLions

  AusAlert cost ~$130 million to rollout. A 13x increase from the $10m initial budget. Here are the known costs and estimates: $10m Initial Planning Taskforce $60-70m Carrier access tolls (Telstra, Optus, TPG) $30m Security architecture & hardening $20-25m Foreign hardware + offshore managed services $5-10m Public awareness, testing & administration Want to know how each allocation is spent? Too bad. Contractors and government use "Commercial-in-Confidence" clauses to keep specific commercial margins and costs hidden from the public eye. A 1300% blowout with no accountability.
