  @Optus Thanks, but that doesn’t address what actually happened. I was in the emergency broadcast area with a compatible device. There was no Optus coverage, but there was coverage from another network. Despite that, I never received the AusAlert. If emergency alerts can’t be delivered when your carrier is unavailable, even though another network is in range, that’s a significant issue. In an emergency, people shouldn’t miss life-saving warnings because of which carrier they’re with. Can you clarify whether AusAlerts are expected to be delivered in this scenario, or is this a limitation of the current system?

  @Adrian_Arciuli @FIFAWorldCup AFL stadiums are not built to support football, I’d take Optus, Adelaide Oval and the MCG off the list! Probably one of the reasons we have never won a World Cup

  Here in Australia we’ve got the semi-annual hand wringing over cellular carriers and emergency calls - is it time to ditch SS7 for VoIP/SIP and switch from single operator SIM from Telstra/Optus to multi-operator SIM like SimBase or ThingsMobile?

  @HappyNacho73 I've got two numbers and the Telstra one on e-sim was very loud compared to the Optus network one.

  @KatyKray73 In the event of a global war, data centres will be prioriy targets for bombs, missiles, and emp nukes, because.... These data centres will control everything. Ffs, telstra and optus outages caused enough disruption, imagine a total testra and optus blackout, multiply that by 100

  @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!.

  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.

  @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

  @MickamiousG @Starlink I got Optus net and have had no problems at all.

  @me_dc And it was totally free this World Cup! Paying for Optus was **** last time
