  @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.

  @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.

  @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).

  @satoshigoy @Optus AusAlert isn’t delivered through @Optus. On LTE, the cell sends a Paging indication 'cmas-Indication-r9' then the warning itself is broadcast in SIB12. A working SIM or successful network registration is not required.

  Our nbn internet/phone service isnt working. A @Optus techician was sent to my home to find out why we dont have nbn internet. He told me there is something wrong with the fibre optic internet cable. The cable brings the internet to our home.

  Go digital they said. What that has got us? MyGov, Telstra, Optus hacked. Stolen identities, etc. This isn't even 1% the problem. Why keep pushing something that causes many problems & stress to everyday ppl? Tracing private citizens every move is the objective.

  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.

  @nicko_316 Thats bad news for Brizvegas if you’re right. Freo will be favourites in that match up at Optus.

  @jnj_pro Hey, J. Customers who log in using email & password also need to perform Multi-factor authentication (MFA). We recommend enabling biometrics in the My Optus App for a faster and secure login, where no extra codes are required. From the 1st of Jan 2026, no conversation history will be stored/available in the My Optus app or My Account online. We understand that this change is a pain point for you, and we've flagged this as feedback for the relevant teams to review. - Dillon

  @AuspiciousTimes @blu_boys @Optus Aldi uses “parts of the Telstra network “ if you read the fine details. Only Boost gives you access to the full Telstra network.

  @HappyNacho73 I've got two numbers and the Telstra one on e-sim was very loud compared to the Optus network one.
