  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.

  @RW2023141 SARAH SHADOW COMM MINISTER NEEDS TO KNOW WHAT OCCURS TO BE FULLY ACROSS PROBLEM . NOT BE FKN HOPELESS LIKE ANNNNIKA SMELLS AND OPTUS OUTAGE DEPARTED OS DURING PROBLEM SILLY SARAH IS HANSON YOUNG YOUR ROBOT ROBERT.

  @Cazzawhy @TigerAncient @SenSHenderson It’s also important that an opposition member of parliament can hold an MP accountable and be aware of lack of access to emergency services to the public in which they serve. Remembering what happened to Optus when people died as a result of losing the same access that was lost yesterday.

  @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

  @JacintaAllanMP Wasn’t Anika Smells supposed to put something in place in the case of such scenarios after the Optus outage? The fault for this lies with Labor

  @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.

  (not to mention, I was in the OPTUS shop when this occured, and has occured many times...) I couldn't send any messages on discord but speed tests were fine, I smell layer 7 sniffing and dodgy QoS to make your network look better...

  @theheraldsun Telstra’s outage affected many states but Victoria’s train network was most affected. Why more than other states? State government stuff up. Optus has had outages too so you shouldn’t be fully reliant on these telcos.
