  @MickamiousG @Starlink When starlink finally get their mobile plans into Australia Telstra will be done within 2 years...one of Vodafone and Optus will survive as a budget telco, but people won't be paying Telstra prices for dogshit service

  @mdtlion She sounds more like a Telstra public relations officer, than the Communications Minister. Maybe she’s grifting for a future job with them. I noticed the little dig she made at Optus by mentioning a previous issue they had had in the past, but totally relevant to today’s issues.

  @Raymartin55 So the opposition communications or health minister shouldn’t check to see if vital infrastructure is working properly Do you remember the Optus outage! Give me a spell!

  @matt_barrie @van00sa And the Optus network went down right after Albanese visited Beijing in November 2023.

  You will hear this more and more... Australia needs another mobile network operator, this will head into a colesworth situation and everyone will suffer.... Wholesaling isn't an option anymore because Telstra and Optus game the system Mark my words, Telop

  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.

  @7NewsBrisbane Why doesn’t 000 have an alternative number as a backup run by? Maybe Optus or Tpg or Vodafone? How does a company or a business run with just one solution? 000 is incompetent.

  @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

  @JH_Otway_Ranges @FranMooMoo Hanlon’s Razor or whatever razor that states never attribute to malice that which can be explained by stupidity. Optus staff literally left a URL public that was supposed to be private and someone stumbled on it.
