  @7NewsMelbourne But you still have to go with an Aus provider as they own the leases on the spectrum it uses and are the only ones to provide service in buildings and high density areas. Optus & Telstra already can provide sms via starlink with calls and data in a few years. So no - the major telcos are not under threat.

  @Optus The advise didn't help. Can @Optus explain why already logged in users still need to do identify verification form as well as verification code. What security concerns the process actually addresses? Compared with putting unnecessary burden and waste time for users.

  @Optus @Optus @OptusNewsRoom when I try to dial out it tells me there is insufficient credit to make a call, when I text the balance check number it shows unlimited calls until the end of the day 31/07/2026 and the current time is midday AEST. Would this be a network issue?

  @nadarnation @rossivision Optus stadium is far superior to Subi. Subi was hideous to get in and out of (both the oval itself and the suburb) , terrible design and horrid to watch football at. Camfield is right next door, Crown a short walk away and great facilities inside the stadium.

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

  @Sueberry2 @blu_boys @Optus Not full Telstra network, limited Telstra network access. Only Boost has full Telstra network access.

  @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.

TCP/IP remains neutral and ethical.

  @iisancs @Optus every two months? mine stops every Two hours, WTF @Optus im tired of this ****, one week will be ok, then next, every two hours it just stops working for for 10 minutes then start again, and its the neighbours having the same issue it s not just me, Dort ya **** out.

  @tiny_watermelon @Optus I just realised I didn't get an alert today either, while I was sleeping. Considering I'm a disabled pensioner that's a little concerning. In the days of landline phones, I was on a high-priority service. Maybe it's because I don't have a smartphone ? Goodness knows.
