  @toninicho I am now, seriously, thinking of changing my carrier after years of being with Optus Problem is Telstra cost me a first full money last time I was with them and I dropped Vodaphone over their poor customer service.

  @JohnCoo51013646 @call_me_tomasso @Leinster_Lad @lesleygood1 @Optus Ah yes, I well remember Telecom and the Post Office, both focused on the customer and delivering quality service.

  @LesStonehouse @Optus There is, I think I remember correctly, a period of up to 48 hours where a new service replicates across a WAN (wide area network).

  @zanekyal Hey, Nicole. It appears that the screenshot shown captures a partially completed Speed Test for your connection to the Optus Mobile Network, as opposed to the same Wi-Fi connection as your TV. We would recommend connecting your phone to the same Wi-Fi connection and completing this again. Should there be any further concerns after this, please don't hesitate to send us a Direct Message, where we can verify some additional information and assist further. - Dillon

  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.

  @strangerous10 The Optus CEO fell on her sword after their nationwide outage a couple of years ago. The Telstra head might go the same way. What were they thinking, laziness, or just penny-pinching.

  @james00000001 @Schtang Optus is not the problem! It's individual users and their settings.

  @Optus are the worst telco on the planet. You’d think that after over 30 years of loyalty they’d be willing to negotiate a compromise and maybe even a little leniency to someone in financial hardship, but no. They don’t care. It’s all about the money. Stay away from @Optus

  🔴 Telstra CEO faces parliamentary inquiry over nationwide outage affecting emergency calls, payments Telstra chief executive Vicki Brady will testify Friday before an emergency parliamentary inquiry into last week's outage that knocked out triple zero emergency calls, disrupted payment systems, and stopped trains in two Australian states. Greens communication spokesperson Sarah Hanson-Young said: "Telstra, just like Optus, has put their profits ahead of public safety and public service for far too long, and the law allows them to." • Telstra accepting compensation claims from affected customers and small businesses with supporting evidence

  @daytona7th @Adrian_Arciuli @FIFAWorldCup I have been to many soccer games at Optus stadium and its been great. They do preseason games there every year for big teams and its never been a bad watch.
