  @1amsharky @DeafMango ENG had better bowlers last time around. This time they don't have quality bowlers. They did really well in the last Ashes down under when they got bouncy decks in Optus, MCG. If theres a flat deck then it would end up in draw as neither teams could take 20 wkts on those surfaces

  @blu_boys @Optus Switch to Amaysim. Half the price still on the Optus network. You can take your phone numbers.

  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.

  @susanmandrews RA seems to be taking quite a unique approach to the women’s rugby program. We have all been through it. Unless it is a significant issue which requires an apology eg Optus/Telstra outages, just put out a holding statement & some spin. RA is lucky not much media interest in rugby

  @strangerous10 The Optus CEO fell on her sword after their nationwide outage a couple of years ago. The Telstra head might go the same way. What were they thinking, laziness, or just penny-pinching.

  @karavas_alex Nah - not playing at the G becomes a bigger myth. Some clubs don’t play at Optus in a season but maybe expected to play a final there. It’s just a mind set, the more it gets talked about, the bigger the issue , we’ll be fine

  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.

  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
