  @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.

  @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.

  @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).

  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.

  @optus_help I’m not entering my personal details to one more Optus representative. This needs to be escalated to the Ombudsman. No one can respond or communicate with me about this issue. And there has been absolutely no effort to restore services.

  @ellensandell The data centres are built by Australian companies you utter imbecile. Do you have problem with data centres built by Goodman? NextDC? Used by Telstra? Optus? Vodafone? How are you such a ******* simpleton?

  @Optus And the session time-out keeps interrupting me when I'm talking to a customer support, I have to log in again after a while. Why is that? Can the product manager explain? The overall experience with Optus apps (Web and mobile) is painful, and a simple request would take days.

  @WestCoastEagles so Milan derby at Optus. In what part of the oval are they going to situate the rather tiny pitch? And are they erecting seating on a surface that's already having problems?

  @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?

  @saline Hi Samela, so that we are on the same page, you have an Optus service and your service is getting cut off at night, especially when you call your colleague Brenda? If you are an Optus customer having issues with your service then please send us a direct message with more details of the fault so that we can assist you further - Kartik

  @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.
