  @strangerous10 The Optus CEO fell on her sword after their nationwide outage a couple of years ago. The Telstra head might go the same way. What were they thinking, laziness, or just penny-pinching.

  @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…

  A guy moved into a new apartment. Only “official” internet was FTTN NBN — $90/month for a pathetic 30 Mbps down max. He called Telstra and Optus. Both said “5G Fixed Wireless not available at your address.” He checked a cell tower map anyway. Half a dozen towers within a couple km. Bought a GL.iNet GL-X3000NR 5G router + built a DIY 4x4 MIMO LPDA external antenna. Result? 800 Mbps download / 170 Mbps upload. 25x faster. $75/month. Same building. Here’s exactly how he did it 🧵

  @BritishHodl Grok can an ISP block voice over IP? 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.

  @JordanTHFCFFC Freo is in trouble anyway. They need Brisbane in the 1/4 game so they can beat them at Optus. If they play anywhere else Brisbanes big game players will win it so they need to hope someone can knock the lions off

  @JacintaAllanMP We saw similar issues with Optus. There is supposed to be redundancy that allows emergency calls to be carried over any available mobile network. If our emergency communications and critical infrastructure are meant to be resilient, why do single network outages continue to have such widespread impacts? It’s time to review whether our redundancy is truly independent, or whether we’re relying on backup systems that share the same points of failure.

  Our nbn internet/phone service isnt working. A @Optus techician was sent to my home to find out why we dont have nbn internet. He told me there is something wrong with the fibre optic internet cable. The cable brings the internet to our home.
