  @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 ****

  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.

  @ALeighMP Didn't get it. iPhone. Optus. On. Fail.

  @KobieThatcher It is same with Telstra Optus and Vodafone. Network monitoring is also done from India.

  @robertveneziano @VoteLewko Incorrect ARTC handles Standard Gauge in AUS... Whist @VicTrack_Vic handles Broad gauge in VIC. But all should not rely on only one telco provider...the ICE radio are linked to Telstra! But optus has gone down too 2 years ago with the same result!

  @Naymmm_ @stupidtechtakes *actually the governments fault for whatever stupid reason, they forced Telstra/TPG/Optus to do these blanket bans on VoLTE capable devices if they weren’t sold locally for whatever reason

  @strangerous10 And they pushed back at global roaming as well. Happens as a default in most countries. Would save a lot of problems if Telstra or Optus shared their networks when network problems arose with any communications provider in Australia 🇦🇺 @AlboMP

  @IanBatchelor11 @australian i worked for origin this exact issue was raised as an issue my manager ( who was at Optus when they had the databreach) said it wasn't an issue
