  @Optus There’s been ongoing issues with the @Optus tower here in Koroit, Victoria for the past few weeks. Maybe someone could look at putting up a new tower?

  @Optus Is actually the web page design that’s the issue- it references something that doesn’t exist on that page. I’ll try your advice. Maybe someone can have a look at the page to ensure it’s helpful… 🤔

  Origin Energy just had 900,000 customers' data breached, joining Optus, Medibank, Qantas and DP World. We treat each as a one-off. A pattern this long stops being bad luck and starts being the cost of collecting data you can't protect. #CyberSecurity #DataBreach

  @amagickeagle999 Listen up ********. She's not expected to run it. She is expected as the responsible minister to oversee the regulatory framework and take the necessary legislative steps to protect consumers and ensure service standards are maintained. She promised tougher oversight after the two Optus outages last year and has done nothing, **** all. Over 600 triple 0 calls failed, lives at serious risk let alone the economic damage. Get it through your thick skull - She dropped the ball.

  @jlandsme_93 The media in WA refuse to press Optus management over it. The drainage system there has issues all the time. The soil develops a slippery biofilm on it due to the **** drainage system

  @FranMooMoo I wonder if his satellites can be used for mobile phone network? Mobile phone calls and text messages don't use much bandwidth unlike the internet, if he were to somehow make phones and they worked everywhere even in the desert Telstra Vodaphone, and Optus would go bust

  can’t watch the game but is it pissing down at Optus? Why can’t anyone kick straight #AFLFreoSwans

  @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.

  @therevaknight Because of Government incompetence, they had no simple backup system, they made NO allowances for technological failure, complexity is the enemy of reliable; the reliability issue was known (ref previous OPTUS outage). NO REDUNDANCY for critical infrastructure! @heidimur

  @7NewsBrisbane Why doesn’t 000 have an alternative number as a backup run by? Maybe Optus or Tpg or Vodafone? How does a company or a business run with just one solution? 000 is incompetent.
