  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.

  @simonbiddle @taipan168 As much as I defend funding government services, the notion that government run IT will be more reliable than Telstra/Optus is just not believable given the various IT issues we see on a constant basis from Centrelink and who can forget the debacle of the last Census

  @lodo25 @Ausbobsmit I’m usually in favour of government owned utilities but in my opinion the only privatised function that appears to work is communications. If there was only Telstra we’d be paying top dollar with no alternatives. I’m with Optus and my wife with Telstra so there wasn’t a problem.

  @thmsenglsh i used to work at telstra and we had even more data breaches and outages than optus did but telstras like besties with every australian media outlet and funds alot of their services so everyone just bags on optus instead, telstra genuinely sucks

  @EVERALDATLARGE Agree Everald. Yes there was a system fault, and yes 000 Failed. And Yes after the Optus problems the Labor Minister for Communication put in place to hopefully fix the problem. Calling for government to leave is a bridge too far. It will take time to fix. It’s not down every day
