  @helphelpandhelp It's the fact that Optus KEPT all the personal info, even of ex-customers. WTF were they doing with licence and passport numbers well after the 100 point check had been done. WHY?

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

  @FreedmFightr1 When OPTUS stadium was built in WA originally they wanted to charge obscene prices for crap pies until the backlash. But that's the mindset. Instead of being grateful. They want to milk the supporters DRY!

  @FOXFOOTY @maxlaughton You would have instant support in the South West but a harder time converting northern suburbs of Perth away from WCE & Freo. Powers above would want northern Perth side to get the extra $$ from more matches at Optus. I am bias but South West Sharks is the way to go!

  @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.

  @theheraldsun Telstra’s outage affected many states but Victoria’s train network was most affected. Why more than other states? State government stuff up. Optus has had outages too so you shouldn’t be fully reliant on these telcos.

  🔔 Optus 2018 was hands down his best test hundred. That was really tough deck.

  @JaniceB72627796 Apparently not an Optus issue

  @OMGTheMess She was supposed to implement a new BCP after the Optus outage. What are we paying her to do? Other than drink champagne on her business class flights? What has she actually achieved? Does anyone know?

  Better get my pre game post out before Optus is full and the network fails to load. Tonight is a test @freodockers . You have studied for it. You have prepared. Now it is time get out there and ace the exam. Harness the nerves and kick between the two big sticks #foreverfreo

  @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.
