  @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

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

  @Cazzawhy @TigerAncient @SenSHenderson It’s also important that an opposition member of parliament can hold an MP accountable and be aware of lack of access to emergency services to the public in which they serve. Remembering what happened to Optus when people died as a result of losing the same access that was lost yesterday.

  @GraemeEtt If it's being sent via Telstra or Optus god help us.

  @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.

  You will hear this more and more... Australia needs another mobile network operator, this will head into a colesworth situation and everyone will suffer.... Wholesaling isn't an option anymore because Telstra and Optus game the system Mark my words, Telop

  @Fallingsky556 I gather she was on the Optus network?

  @therevaknight Because of Government incompetence, they had no simple backup system, they made NO allowances for technological failure, complexity is the enemy of reliable; the reliability issue was known (ref previous OPTUS outage). NO REDUNDANCY for critical infrastructure! @heidimur

  @EVERALDATLARGE Many have said their Telstra provider phone worked but not their Optus. I even saw one question regarding Vodafone. Is it a provider issue perhaps?

  @EVERALDATLARGE Agree Everald. Yes there was a system fault, and yes 000 Failed. And Yes after the Optus problems the Labor Minister for Communication put in place to hopefully fix the problem. Calling for government to leave is a bridge too far. It will take time to fix. It’s not down every day
