  @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.

  @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

  @FelixCLC_ What's been the biggest problem you've faced using Optus with hardware design ?

  @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?🤡

  @IanBatchelor11 @australian i worked for origin this exact issue was raised as an issue my manager ( who was at Optus when they had the databreach) said it wasn't an issue

  @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.

  @Birdsperch Clearly no contingency for terrestrial fail [all eggs in one basket] even with satellite backup downlink distribution relies on terrestrial bearers (circuits), Even Optus with satellite support incorporates terrestrial distribution -Contingency planning is key & costs money

  @BigDog_USA @Telstra You must be deaf and blind. It was a massive outrage when Optus went down too. Not everything is about an agenda **** head.

  @TweetTreet @tim_blee That's bullshit, devices EFTPOS and similar devices that run on 4G/5G can use other networks, and a bit of business continuity planning would have a backup network, even for a small business, like running down to Officeworks and buying an OPTUS prepaid SIM.
