  @satoshigoy @Optus AusAlert isn’t delivered through @Optus. On LTE, the cell sends a Paging indication 'cmas-Indication-r9' then the warning itself is broadcast in SIB12. A working SIM or successful network registration is not required.

  @tonyward116 @Batman2242 Optus was probably down again.

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

  @JoGu1802 It was because Optus no longer supported the iPhone 5 on its app that I upgraded. Because it’s DAMN hard to use the app to prepay for your phone when the app doesn’t… support your phone…

  @OMGTheMess It only happened recently with Optus. Anika Wells didn’t fix it, did she?

  @Gizmologist_ Funny how telco’s never had this problem before wouldn’t surprise me if Telstra orchestrated Optus outage to knock them out of the market like Qantas did to Rex blocking airports We’ve had polair lately at night doing thermal mapping of the area fly round almost 2hrs each time

  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.

  @keating01 Isn’t OPTUS & Telstra’s outage breakdown a strong reason NOT TO go digital on everything under one system of Government control? How many different services went out - not just 000? Can’t bank, buy petrol, grocery, use your card! EVEN WORSE is if we have a power supply outage!

  @StMaryMacKiller So bad the iPad has an Optus chip and the house has been in Starlink for years

  Data Security seems to be a major problem in Australia. How about I just hand my data over publicly and be done with it? @Optus @originenergy #DataSecurity
