  Wondering whether the Telstra CEO Vicky Brady will break down and cry when she fronts up to the media about the system outage, just like the Optus CEO Kelly Bayer Rosmarin did, following the system outage in 2022?

  The fact that the emergency AusAlert didn’t reach Optus customers who had no Optus coverage, despite Telstra towers being available, is absurd. An emergency warning system should use any available network to deliver life-saving alerts—not fail because your own carrier is down. In a disaster, network loyalty shouldn’t determine who gets warned. This needs to be fixed before the next emergency.

  @realRick_AUS We need him to have a full mobile network so we can piss Telstra and Optus off forever

  @alex_prompter The problem is Fable isn't actually worth using. Optus ultra is a better all rounder

  @MikeCarlton01 @Telstra That would be vodafone followed by optus and then telstra. Before anyone comes after me, vodafone went down for several months in 2010/2011, optus had a data breach in 2022 that affected nearly 10 million customers. Telstra just inconvenienced people.

  @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.

  @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.

  Our nbn internet/phone service isnt working. A @Optus techician was sent to my home to find out why we dont have nbn internet. He told me there is something wrong with the fibre optic internet cable. The cable brings the internet to our home.
