  @blu_boys @Optus Switch to Amaysim. Half the price still on the Optus network. You can take your phone numbers.

  @Optus @OptusNewsRoom @Optus I also have been experiencing problems with apps loading despite having 4G.

  @tonyward116 @Batman2242 Optus was probably down again.

  @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.

  @KobieThatcher @Ann19851873 Agree 💯 Also with the recent Telstra outage and formed Optus outage. Both affecting Eftpos networks and ATM’s. Cash is king for many reasons including privacy. Do not let cash die out.

  @jnj_pro Sorry to hear that you're having these ongoing issues with the app and need to log in multiple times. Can you please ensure both the app and your device have been updated to the latest available software? We also recommend enabling biometrics in the My Optus App, so you don't need to keep re-entering codes. Please send us a DM if you are still needing assistance. - Joel

  Imagine cancelling a family plan & replacing it with another service, funnily enough which costs more. Customers needs aren’t changing, your greed is. @Optus, this is appalling & just outright greedy. I will be taking my business elsewhere, along with future required services.

  AusAlert cost ~$130 million to rollout. A 13x increase from the $10m initial budget. Here are the known costs and estimates: $10m Initial Planning Taskforce $60-70m Carrier access tolls (Telstra, Optus, TPG) $30m Security architecture & hardening $20-25m Foreign hardware + offshore managed services $5-10m Public awareness, testing & administration Want to know how each allocation is spent? Too bad. Contractors and government use "Commercial-in-Confidence" clauses to keep specific commercial margins and costs hidden from the public eye. A 1300% blowout with no accountability.

  Does everyone know you can dumb down the Claude model to get around prompt restraints in Optus and above yeah ?
