  @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).

  @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.

  @Sharkies2035 Hi there, I'm sorry to hear about your poor experience with Optus' prepaid plans. We'd like the opportunity to turn this around for you. Please send us a Direct Message with more information so that we can investigate further. -San

  @theheraldsun Telstra’s outage affected many states but Victoria’s train network was most affected. Why more than other states? State government stuff up. Optus has had outages too so you shouldn’t be fully reliant on these telcos.

  @OMGTheMess It only happened recently with Optus. Anika Wells didn’t fix it, did she?

  @benny_drew @7AFL Don't forget they lost to Gold Coast at Optus Oval in the finals last year by 1 point. They'll **** it up like they always do.

  @optus_help Hey Sam, I wasn't logged in and not even an Optus customer. Do you want me to DM the original enquiry so that it is easier to find the conversation?

  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.
