  @TweetTreet @tim_blee That's bullshit, devices EFTPOS and similar devices that run on 4G/5G can use other networks, and a bit of business continuity planning would have a backup network, even for a small business, like running down to Officeworks and buying an OPTUS prepaid SIM.

  @JohnnyinternetI @WestCoastEagles AFL had nothing to do with Optus build. Such a stupid comment.

  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.

  @Optus This morning, just after 11am, I noticed that my @Optus @NBN_Australia connection stopped working, resulting in no internet or telephone service. I’m located in the Inner West Sydney area. Is this an unscheduled outage. What is going on? This is so frustrating!

  Better get my pre game post out before Optus is full and the network fails to load. Tonight is a test @freodockers . You have studied for it. You have prepared. Now it is time get out there and ace the exam. Harness the nerves and kick between the two big sticks #foreverfreo

  @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

  @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

  @matt_barrie @van00sa And the Optus network went down right after Albanese visited Beijing in November 2023.

  Why in a capital city do all fail with internet coverage In out back Truganina phones and internet mobile connection are a massive fail. @Telstra @Optus @amaysimAU

  The Optus Stadium surface is simply the worst; it’s worse than those arena shows that do Disney on Ice
