  @VoteLewko On my mates farm in the coast they have redundancy (Starlink) & anothet mate who runs ASIC’s infrastructure says they have always had both Telstra & Optus to try & avoid over reliance on a single network. So if farmers & some federal bureaucrats know this why don’t Victoria’s?🤡

  @david89293299 Where was the communications minister moron? Some one needed to step up and actually test it! Not like the the bungled Optus uggrade where the 000 outage went unnoticed for hours. Smart and proactive! Not something you Labtards would know anything about

  @heidimur This isn’t just about Telstra. We saw similar issues with Optus. 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 backups that share the same points of failure.

  @james00000001 I now think not an Optus problem as my husband received the alarm and he is on the same service as me. If I don't get anything I will contact Optus to find out why not.

  Why is it the USA can communicate with a space ship circulating the moon but Australia has such a hard job communicating with a ******* train just around the corner.. Because of this useless waste of space Anita Wells…. WHY is Australia STILL relying on just a single network for the train networks and 000 and a host of so many essential infrastructure ?? WHY hasn’t our government, especially after the Optus outages just changed the laws to the filthy rich telecommunications companies that they have to combine both networks together for things of major importance to the running of the country ?? 000 and train networks. You want a communications licence… fix the bloody thing so at least BOTH Telstra and Optus are both responsible for the safety of Australia and every Australian.. @AngusTaylorMP @PaulineHansonOz

  @OMGTheMess It only happened recently with Optus. Anika Wells didn’t fix it, did she?

  @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.

  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.

  @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
