  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.

  @MikeCarlton01 @Telstra That would be vodafone followed by optus and then telstra. Before anyone comes after me, vodafone went down for several months in 2010/2011, optus had a data breach in 2022 that affected nearly 10 million customers. Telstra just inconvenienced people.

  @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!

  @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?

  @therevaknight Because of Government incompetence, they had no simple backup system, they made NO allowances for technological failure, complexity is the enemy of reliable; the reliability issue was known (ref previous OPTUS outage). NO REDUNDANCY for critical infrastructure! @heidimur

  @m_aryel_len @james00000001 Not true. I was updated. Didn't get it. Partners wasn't updated. He did. Same Optus network.

  @MiddleMoney @aussiewongm @Anneeokeefe I'm pretty sure Metro went down during the Optus outages last year. But restoration time was quicker iirc.

  Data Security seems to be a major problem in Australia. How about I just hand my data over publicly and be done with it? @Optus @originenergy #DataSecurity
