  @JohnnyinternetI @WestCoastEagles AFL had nothing to do with Optus build. Such a stupid comment.

  @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.

  @nemagovau If i receive the alert on the phones i had to replace because they couldn't call one number on one network that i don't use, "000" on Voda network. Then i want those phones imei numbers reinstated on the Telstra & Optus, that i have sims for. The public/private partnership scam

  @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!

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

  Why is it the USA can communicate with a space ship circulating the moon but Australia has such a hard job communicating with a ******* train just around the corner.. Because of this useless waste of space Anita Wells…. WHY is Australia STILL relying on just a single network for the train networks and 000 and a host of so many essential infrastructure ?? WHY hasn’t our government, especially after the Optus outages just changed the laws to the filthy rich telecommunications companies that they have to combine both networks together for things of major importance to the running of the country ?? 000 and train networks. You want a communications licence… fix the bloody thing so at least BOTH Telstra and Optus are both responsible for the safety of Australia and every Australian.. @AngusTaylorMP @PaulineHansonOz

  @OMGTheMess She was supposed to implement a new BCP after the Optus outage. What are we paying her to do? Other than drink champagne on her business class flights? What has she actually achieved? Does anyone know?

  @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.
