  @corduroy @Optus Last year Telstra was the same man. They just have no clue about customer service.

  @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.

  @heidimur This isn’t just about Telstra. We saw similar issues with Optus. If our emergency communications and critical infrastructure are meant to be resilient, why do single network outages continue to have such widespread impacts? It’s time to review whether our redundancy is truly independent, or whether we’re relying on backups that share the same points of failure.

  @Optus This morning, just after 11am, I noticed that my @Optus @NBN_Australia connection stopped working, resulting in no internet or telephone service. I’m located in the Inner West Sydney area. Is this an unscheduled outage. What is going on? This is so frustrating!

  @jbulldogs4 Not really as its still ongoing. They told people to use a optus or vodafone device thats not Telstra. Thats some reliable service isnt it. Shouldn’t be happening but probably a overseas disgruntled workers!.

  @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.

  @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

  @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.

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