  @roodave didn't Metro in Melbourne get hit by an Optus outage a couple of years back?

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

  @nadarnation @rossivision Optus stadium is far superior to Subi. Subi was hideous to get in and out of (both the oval itself and the suburb) , terrible design and horrid to watch football at. Camfield is right next door, Crown a short walk away and great facilities inside the stadium.

  @PaulBongiorno Oh woe is me ! Just purchase a sim card supported by Optus [this is redundancy contingency] when Telstra goes off line swap out their sim & slot in the backup & vice versa. Alteratively purchase a dual sim phone which allows you to switch between service providers

  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.

  @Kate3015 Kate i think the Labor communication minister Anika Wells should be the one getting the kick up the arse because she was in charge when optus had their outage and said she was going to fix it obviously she hasn't

  @BonnieLerino123 How absurd Really this is the hill they want to die on ? Common sense after what happened with Optus and NO ONE GAVE A DAMN PEOPLE COULDNT CALL 000 AND DIED THANKYOU SARAH FOR YOUR QUICK ACTION

  @TimjboAU Remember a week ago when the entire telstea network went down? Remember a month before that when the entire optus/tpg network went down? Now next week we have the entire network government alert thing happening? Yeah, those network outages were 100% preparation for next week.
