  @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

  @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.

  @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.

  @FOXFOOTY @maxlaughton You would have instant support in the South West but a harder time converting northern suburbs of Perth away from WCE & Freo. Powers above would want northern Perth side to get the extra $$ from more matches at Optus. I am bias but South West Sharks is the way to go!

  @Kate3015 Remember 18 Sept 2025 when Optus had a 000 outage because no one though to make some test calls to ensure the service was working after an upgrade? Doing a test is basic common sense.

  @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

  Here in Australia we’ve got the semi-annual hand wringing over cellular carriers and emergency calls - is it time to ditch SS7 for VoIP/SIP and switch from single operator SIM from Telstra/Optus to multi-operator SIM like SimBase or ThingsMobile?

  @JacintaAllanMP Wasn’t Anika Smells supposed to put something in place in the case of such scenarios after the Optus outage? The fault for this lies with Labor
