  @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.

  Why does @Optus now require a direct debit to be setup if you want to change your internet plan? I have had post paid plans with Optus for years and never an issue but now have been told it is the only way😡

  Our @optus NBN internet/Phone service problem has been fixed. My mother can watch online movies and music videos on youtube. The internet is her only source of entertainment

  @strangebaaza @RjeyTech Well, I beg to differ. My previous fold 4, S22 ultra, fold 6, the current fold 7 and s26 ultra all had or have green line screen issues while my iPhone 12 pro, iPhone 14 pro max and 16 pro max still going strong, no issues whatsoever. All cost pretty much the same but Samsung quality is subpar, and service is shite. I still ordered the fold 8 as currently it is available for $0 via Optus Harvey Norman Australia. Bet you, it will also likely have this screen issue. No matter what Samsung does, somehow manages to create overpriced paperweights.

  In what they claim is a world first, $NOK and Optus used a robot dog to measure mobile coverage and design 6G networks. They also conducted a 6 GHz spectrum trial, in which a user could download a 2 hour HD movie in just a few seconds, or support over 140 simultaneous 4k video streams.

  @Optus And the session time-out keeps interrupting me when I'm talking to a customer support, I have to log in again after a while. Why is that? Can the product manager explain? The overall experience with Optus apps (Web and mobile) is painful, and a simple request would take days.

  @EVERALDATLARGE Many have said their Telstra provider phone worked but not their Optus. I even saw one question regarding Vodafone. Is it a provider issue perhaps?

  @QBCCIntegrity Australians are now being subjected to more and more data breaches. I have friends with Optus and Energex who are at a loss as to what to do. Bank details, card details, DOB. Banks cancel your cards in times of dispute. Direct debits are affected. Constant crimes against us all.
