https://stream.echo6.co/videos/watch/e2b2c374-dd34-48a9-b74a-9a6b2dbf8403 In this video I show you have to capture VoIP (Voice over IP) phone calls and replay them. We'll capture both the SIP messages and the actual RTP and replay it. I'll show you multiple ways of doing this including: using a Network Tap, ARP Poisoning Man in Middle attack, even using a Hub, Be careful if you are using a PBX and SIP phones - are the calls actually encrypted? Are you using SSL and SRTP? FreePBX in this example doesn't do that. Disclaimer: I gave myself permission to capture and replay my own phone calls. Only ever capture and replay calls you have permission to. // David's SOCIAL // Discord: https://discord.com/invite/usKSyzb X: https://www.twitter.com/davidbombal Instagram: https://www.instagram.com/davidbombal LinkedIn: https://www.linkedin.com/in/davidbombal Facebook: https://www.facebook.com/davidbombal.co TikTok: http://tiktok.com/@davidbombal YouTube: https://www.youtube.com/@davidbombal Spotify: https://open.spotify.com/show/3f6k6gERfuriI96efWWLQQ SoundCloud: https://soundcloud.com/davidbombal Apple Podcast: https://podcasts.apple.com/us/podcast/david-bombal/id1466865532 // MY STUFF // https://www.amazon.com/shop/davidbombal // SPONSORS // Interested in sponsoring my videos?

Hacking VoIP shows how deep networking really goes. It feels like being a digital spy. Capture RTP packets with Wireshark Filter traffic using port 5060 (SIP) and UDP (RTP). Wireshark captures and analyzes SIP, SDP, and RTP protocols in real-time. Kali Linux includes tools for VoIP analysis and attacks. Wireshark captures VoIP traffic for inspection. SIP packets reveal call metadata and credentials. Man-in-the-middle attacks capture VoIP conversations. Ettercap helps intercept VoIP traffic. Unencrypted VoIP is vulnerable to eavesdropping.
