  @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!

  So we have another outage impacting 000 calls in Australia, this time by Telstra. This has already happened with Optus twice if I recall. Enough is enough. Renationalise Telstra and Optus, and give them all the funding needed to maintain, develop and expand our telecommunications infrastructure across Australia in the interests of the people rather than private and foreign shareholders. #auspol

  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.

  Optus stadium turf has been shockingly bad lately. Players slipping everywhere as that top layer is shifting too easily, reckon we’ll see an injury soon

  @NoticerNews Same reason for the recent Optus outage. This woke CEO & Labor government needs to swing.

  @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

  @nadarnation @rossivision Optus stadium is far superior to Subi. Subi was hideous to get in and out of (both the oval itself and the suburb) , terrible design and horrid to watch football at. Camfield is right next door, Crown a short walk away and great facilities inside the stadium.

  @optus_help Hey Sam, I wasn't logged in and not even an Optus customer. Do you want me to DM the original enquiry so that it is easier to find the conversation?

  Our @optus NBN internet/Phone service problem has been fixed. My mother can watch online movies and music videos on youtube. The internet is her only source of entertainment
