  @RoadknightThe Mine didn't work on Telstra. The optus phone did. FAIL

  We need the telco to learn #auspol but as an Optus customer .who has seen it before, what happens hear? Zero cash for us, but the Optus bill goes up to cover this pay out to lawyers and a few who could afford them. Same as the mob who are suing Coles. Pays lawyers and a few and we all pay the price in the new prices, not Optus or Coles

  Hey paul...Labor promised they'd get to the bottom of the optus outage.. Any idea why they walked away from the problem and allowed it to happen again.

  @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.

  Doesn’t seen to be the same outrage with Telstra outage than Optus 🤔

  @CharlesSzulc Telstra will appear before a Senate inquiry into its outage, starting next Friday. Senator Henderson is involved in the (apparently ongoing) Optus one. It'll be be interesting if she now asks questions of Telstra, as will be forthcoming media reports.

  @jfwfreo @D_LittleproudMP Exactly. I live remotely, and the local tower broke down. It took 3 weeks for Optus to arrive. Meanwhile I used the local pay phone most days to conduct business and to phone concerned friends and relatives. Littleproud has no idea how the remote live. He’s just another National

  @james00000001 Interesting to see if they were Optus phones that didn’t receive the message - wouldn’t be surprised Optus is so ****

  @tim_blee You would think that if you relied on the mobile network to receive payments then you would have a backup should the particular network fail. Maybe have an Optus or Vodafone SIM card handy or re-route your payment system to the NBN? No sympathy for unprepared businesses.

  @Gizmologist_ Funny how telco’s never had this problem before wouldn’t surprise me if Telstra orchestrated Optus outage to knock them out of the market like Qantas did to Rex blocking airports We’ve had polair lately at night doing thermal mapping of the area fly round almost 2hrs each time
