  @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.

  @alex_prompter The problem is Fable isn't actually worth using. Optus ultra is a better all rounder

  @realRick_AUS We need him to have a full mobile network so we can piss Telstra and Optus off forever

  @FranMooMoo I wonder if his satellites can be used for mobile phone network? Mobile phone calls and text messages don't use much bandwidth unlike the internet, if he were to somehow make phones and they worked everywhere even in the desert Telstra Vodaphone, and Optus would go bust

  @rossivision Optus Stadium is elite but getting in and out of it sucks.

TCP/IP remains neutral and ethical.

  @benny_drew @7AFL Don't forget they lost to Gold Coast at Optus Oval in the finals last year by 1 point. They'll **** it up like they always do.

  @iisancs Hi Isan, we're sorry to hear you're experiencing issues with your internet connection in spite of paying your monthly Optus bill. Please send us a DM with your full service address and your internet type, so we can take a look and investigate further. -Enku

  One Telstra glitch this morning and half the country stopped working. Some clocks fell out of sync across a few network nodes at 4:30am and that was enough to ground every regional train in Victoria, suspend lines in NSW, knock out payments for small businesses, stop freight, and some 000 calls weren’t getting through. Boost, Aldi Mobile and Belong all run on Telstra’s network so their customers went down too. 25 million services are on this network. They don’t know the root cause yet. Optus went down for 14 hours last year and 2 people died when emergency calls couldn’t connect, now it’s Telstra’s turn. This is the infrastructure they want your ID, your payments and your entire life running through.

  @BonnieLerino123 How absurd Really this is the hill they want to die on ? Common sense after what happened with Optus and NO ONE GAVE A DAMN PEOPLE COULDNT CALL 000 AND DIED THANKYOU SARAH FOR YOUR QUICK ACTION
