  Oh, but @triplej is far-less-national than I understood. Still a big chunk of this drive where neither broadcast radio or @optus signal penetrate.

  @Sammy__Edmund @SENBreakfast The surface at Optus has been **** for years

  @DelloPicks Worth noting he has only missed 14 at Optus once this season as is, which was probably a career worst game.

  @JaniceB72627796 I'm wondering if Optus had a problem. Will be interested to hear if you receive it later

  @TimjboAU Remember a week ago when the entire telstea network went down? Remember a month before that when the entire optus/tpg network went down? Now next week we have the entire network government alert thing happening? Yeah, those network outages were 100% preparation for next week.

  @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.

  Telstra network issues rumble on in qld. Messages delayed Calls dropped. How's Optus & Vodaphone doing?

  The fact that the emergency AusAlert didn’t reach Optus customers who had no Optus coverage, despite Telstra towers being available, is absurd. An emergency warning system should use any available network to deliver life-saving alerts—not fail because your own carrier is down. In a disaster, network loyalty shouldn’t determine who gets warned. This needs to be fixed before the next emergency.

  @Fallingsky556 I gather she was on the Optus network?

  @PaulBongiorno Oh woe is me ! Just purchase a sim card supported by Optus [this is redundancy contingency] when Telstra goes off line swap out their sim & slot in the backup & vice versa. Alteratively purchase a dual sim phone which allows you to switch between service providers

  @twensor @FetchStep sadly its totally on form for telstra. remember when a small fire in their chatswood building took out the national SMS network. where i live telstra, nbn, optus and vodafone are all on a 4 hour battery backup, while essential energy schedules regular 8 hour outages.
