  @BigDog_USA @Telstra You must be deaf and blind. It was a massive outrage when Optus went down too. Not everything is about an agenda **** head.

  @simonbiddle @taipan168 As much as I defend funding government services, the notion that government run IT will be more reliable than Telstra/Optus is just not believable given the various IT issues we see on a constant basis from Centrelink and who can forget the debacle of the last Census

  @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.

  @jbulldogs4 Not really as its still ongoing. They told people to use a optus or vodafone device thats not Telstra. Thats some reliable service isnt it. Shouldn’t be happening but probably a overseas disgruntled workers!.

  @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.

  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

  Is #Optus NT #Darwin experiencing connectivity issues last few days ?

  @Kate3015 Aussies are being fleeced, these comms companies compared to everywhere else in the world take Aussies to the cleaners. For the entire network to fail would suggest a complete & utter rebuild of Telstra is required urgently, from the very top down. #Telstra #Auspol #Optus

  @EVERALDATLARGE Agree Everald. Yes there was a system fault, and yes 000 Failed. And Yes after the Optus problems the Labor Minister for Communication put in place to hopefully fix the problem. Calling for government to leave is a bridge too far. It will take time to fix. It’s not down every day

  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.
