  @me_dc And it was totally free this World Cup! Paying for Optus was **** last time

  @Naymmm_ @stupidtechtakes *actually the governments fault for whatever stupid reason, they forced Telstra/TPG/Optus to do these blanket bans on VoLTE capable devices if they weren’t sold locally for whatever reason

  @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.

  @BinManIan Even if we were to propose the oval stadiums, the AFL is too greedy and has too much influence, they'll never allow the use of the MCG, Adelaide Oval and Optus Stadium for a month

  @Adrian_Arciuli @FIFAWorldCup MCG, Optus and Adelaide are Ovals and non starters. Cake Tin would and should be knocked down to expand. Given cricket isn't played there it would be rectangular, By 2042 Stadium Australia will have been rebuilt Perth should have a 40k rectangular Hopefully expanded Coopers

  @james00000001 Interesting to see if they were Optus phones that didn’t receive the message - wouldn’t be surprised Optus is so ****

  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

  Further update, Mum was just on the phone with Optus and apparently Optus (an internet provider) isn’t able to call NBN to fix this, they can only text message them. Or at least that’s the line they are spitting out about the network degradations DO YOUR JOB!!!

  @PaulBongiorno Oh woe is me ! Just purchase a sim card supported by Optus [this is redundancy contingency] when Telstra goes off line swap out their sim & slot in the backup & vice versa. Alteratively purchase a dual sim phone which allows you to switch between service providers

  I’m wondering if Telstra Optus etc will cope on Monday 27th when all the emergency services etc are planned to be delivered to phones
