  @nemagovau If i receive the alert on the phones i had to replace because they couldn't call one number on one network that i don't use, "000" on Voda network. Then i want those phones imei numbers reinstated on the Telstra & Optus, that i have sims for. The public/private partnership scam

  @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.

  @zanekyal Hey, Nicole. It appears that the screenshot shown captures a partially completed Speed Test for your connection to the Optus Mobile Network, as opposed to the same Wi-Fi connection as your TV. We would recommend connecting your phone to the same Wi-Fi connection and completing this again. Should there be any further concerns after this, please don't hesitate to send us a Direct Message, where we can verify some additional information and assist further. - Dillon

  @VoteLewko On my mates farm in the coast they have redundancy (Starlink) & anothet mate who runs ASIC’s infrastructure says they have always had both Telstra & Optus to try & avoid over reliance on a single network. So if farmers & some federal bureaucrats know this why don’t Victoria’s?🤡

  @WesleySouthcott @ScomoCchio No. Optus has had outages too. And their response was just as pathetic as Telstra’s. But the point remains, huge service providers that can cause disrupt/impact nationwide are not held to account in any meaningful or significant way.

  @BinManIan Even if we were to propose the oval stadiums, the AFL is too greedy and has too much influence, they'll never allow the use of the MCG, Adelaide Oval and Optus Stadium for a month

  @Optus are the worst telco on the planet. You’d think that after over 30 years of loyalty they’d be willing to negotiate a compromise and maybe even a little leniency to someone in financial hardship, but no. They don’t care. It’s all about the money. Stay away from @Optus
