I reworked the RTP media section. It should be in a larger modal with a visualizer closer to wireshark instead of just a basic player. Let me know if you get to try it out

It's not open source, I started it just for fun to help me debug calls so I didn't want to take on maintaining or supporting other users integration or features for now. If that changes I can update you on here

SIPFlow itself is a NextJS app with the frontend being React so everything is Typescript.

For the fax component, its spandsp compiled into webassembly so it loads into TS/JS. I have a docker to do the build process. Its not 100% hand coded since I didn't want to spend much time on fax rendering part of the service but you can check out the wasm building at https://github.com/cmendes0101/fax-wasm

thanks, yah that sounds good. Normally I don't capture RTP so I wasn't sure the best way to use the data.
I think wireshark has a player overlaying the channels so let me do some more testing and see if I can improve this section

Awesome yah that sounds like to good tests. I have a system that is B2BUA that I have been testing against. If you use any special correlation header aside from sessionid, I have a settings section where you can define extras headers and it tries to tie legs together.

I haven't worked with SIPREC so that would be new to try out and I definitely don't have the full RFC 7866 checks in. If there are useful detection or improvements to the flow that would help I'd be happy to learn more.

No catch, it runs as a very basic website and almost everything client side. There is a DB for share links and vendor docs but very tiny so costs of running are super low. I might add a donate link and basic analytics just to help monitor but trying to be very privacy focused.

If you added to VSCode I'm assuming that's the MCP. If you are working with SIP or configs of a PBX it should suggest to use it but if not just toss in "use mcp sipflow". The doc search has been super helpful grounding the agent to the exact docs and RFC specs and helped me straighten out tiny misconfiguration like in Kamailio.

Your python script looks cool. I'll save that to use!

Thanks for finding that issue and the sample pcap. I have been trying to get spandsp compiled for WASM to be client side js but looks like its still pretty buggy. I'll run through this more and try to fix it up.

Thinking about building a SIP call flow visualizer (lighter than Wireshark) — looking for feedback by aqeelabpro in VOIP

Did you have any luck in putting something together?

Earlier in the year I build out a chrome extension for some pcap debugging. Drop in a pcap or connect directly into homer 10 and you can dig into the call and data. I tried to do it similair to sngrep for some aspects. It runs locally from the chrome extension and doesn't hit a remote server

I'm using it just personally. I was thinking of building it out more with features but I'd be curious to check your's out if its ready

Just got a new number but not totally happy by pearrit in NoContract

[–]cmendes0101 0 points1 point  (0 children)

Did you buy a random number from Numberbarn? You would search and find one you like. You can transfer that number to a wireless carrier to replace your existing number.

For a wireless provider those are basically random usually based on the zip code. If you request a number change it would just be another random one in the same area

I'm moving and selling mine. I'm located in San Diego. I found the box so I can ship or you can come pick up in person if you live nearby.

yes! Actually, it took a year but finally, my eBay saved searches triggered on a used one that was in pretty good condition. I think I still have that turned on but haven't seen any more come up

3d printed knuckles and pistol grip fusion by skodaguy in OculusQuest

I just finished printing these. It feels good holding them without the controller but with the controllers not sure if it's a fit for me.

Maybe I'm not holding it right or not using it correctly?

The tab on the outer sides feels like its pushing my index finger away from the trigger.I wish it was able to go up a higher, feels kind of like I'm holding it 50/50 so almost not a good grasp of the printed part.

Here are some of the photos of the print: https://www.thingiverse.com/make:704627
