SIP Tutorial: How to find all calls for a particular number in large traces
This video will help you when somebody sends you 24 hours worth of traces in one or many files and you need to find all calls to and from a particular phone number.
I apologize I did have to blur some parts of the video to protect the innocent. I also started this video with a completely different method in mind, but as I made the video I found a faster method and just decided to cut the other method all together.

Converting G.729 codec to playable audio
Переглядів 10 тис.9 років тому
I cut this piece of video from another presentation because I think it is something important for people to learn. It was buried in my video on how to trouble shoot choppy audio. This video will teach you how to convert a packet capture with G.729 packets into playable audio. As you probably know, G.711 can do this right inside wireshark, however, G.729 cannot. Hope this helps somebody!

Thank you for this insight into the packets. As a domain admin it is good to see the other side of the DHCP server I manage :)
Man, this is very helpful. Thank you very much for the informative SIP content
hello sir what does it mean 401 Unauthorized and 500 Internal server error . SIP outgoing call not working after analyses the packet flow i received this
Hi such a nice work, how did you get traces from different machine and combine them into one file?
Going for a CO field position with Verizon... Thanks for the overview... Will help with my interview!
how to identify if there no audio from both side i mean sender (caller) and callee(receiver) and this is happening for outbound external call only(When we call any germen number that scenario) give me some suggestion how i can find the root cause because i have checked from external SBC to Internal SBC no packet loss ,even no rule in firewall side ?
Mr. Terrell. Almost all the videos on the Wireshark use coloring without explanation and that is not only confusing but annoying. Plus they don't explain it at step one.
Really good introduction to wireshark. Would love if you'd update it, or give insight into your most used wireshark capabilities in telecom today.
Hiw do i get intouch, i need your support service.
When would you take a packet capture and when to take call logs?
Thank you for making this video. It’s helping me a lot to get Spectrum ESG to work with UniFi talk.
Seriously lovee it
I didn't get. What's the difference between hybrid port and trunk port who's native vlan is not 1. If you can set trunk port's native vlan for instance 200, then what's the purpose of hybrid port?
In this switch, a trunk port does not support untagged packets. If you want both tagged and untagged it needs to be a hybrid port.
@@TerrellBoyer But in general (not this switch) trunk port with untagged other vlan is the same?
@@RobA92 correct
@@TerrellBoyer Thank you very much!
Yay I can understand your video
Thank you for these videos sir!!! Excellent explanation of SIP!
excellent video, still relevant and helpful today.
Thank you
If you click to Media Port: by RightMouseButton and select "Apply as Column" then rewrite that SDP Media Port will be easier. Very good toturial, I hope you are well and you publish some new video, maybe with FreePBX Toturial ...
thank you very much. Your video is really interesting , i learned a lot !
thanks for the content, really interesting ! How is it possible to regroup different traces with wireshark like you do during the video ?
thanks for sharing very helpful and clarifying
ua-cam.com/video/UE_RO9nISt4/v-deo.html
Well explained.
Informative video. Could please help me how did you open packet tracer, how it's launched to see the traffic. Can we open on our desktop?
Hello, not sure if you still respond here. Just trying. I watched your outbound tutorial on SIP Troubleshooting for Beginners - Outgoing Call Trace Review. I am needing to understand how to set up traces to show the RTP stack. Currently I am unable to figure out how to incorporate the RTP/Audio information in my PCAPS. Any help on this would be appreciated. Thanks, Raheem
it worth it subscribing to your channel , thanks a lot
very well explained...thank you
Thanks for sharing. Even today, nearly 7 years later, it's still helpful. I think in the meanwhile Wireshark might be able to natively decode G.729
Great video, thanks
Great job, thanks very much!
Useful video, thanks!
Please add new videos
Thank You!
thanks
hi, thanks for the video very interest, but i have a question, hope you can get me a solution. this is about sip calls and rtp. i have filtered one call and i have more than one direction of rtp flows. im using wireshark version 3.4.4. when i play the rtp it plays all together. can i play one direction at a time. just like in this video. select the stream and play it in version 3.4.4..
Where is the troubleshooting part of finding the cause of this choppy or garbled audio?
thank you for this nice video on SIP.
Great tutorial. Thank you! I struggle to follow call ladders on a daily basis... no more.
👍
Song?
Is this an open source tool?
Unfortunately not. It's quite expensive and costs a couple of thousand Euros and needs a yearly subscription as well.
Nice way to see supported options* 😀
Great work pls i need help on SIP congestion
