Every now and then I hear about providers that refuse to hand over the VoIP SIP credentials.
If you do have access to your modem, you can Wireshark the WAN side, then reset the modem and capture traffic until it has obtained the VoIP information:

Veel mensen op het forum van Telfort vragen zich af of ze de SIP gegevens kunnen krijgen voor telefonie zodat men de ExperiaBox niet hoeven te gebruiken. Gezien dat de Telfort Support deze gegevensā¦

Cool set of steps on [WayBack]Ā How I use Wireshark – Julia EvansĀ who uses the combination of tcpdump to dump traffic in pcap files and Wireshark to analyse the pcap files after copying them using scp. On many platforms, Wireshark can also capture the ptrace files for you.
Via:Ā [WayBack] šJulia Evansš on Twitter: “how I use Wireshark https://t.co/j699JXrjaH”Ā which has some nice comments including:
- adding
ptrace to your tool-kit
- not needing
scp for copying, as you can do [WayBack] dumpcap over an existing ssh connection:
- You might like this snippet, saves you the need to do the scp dance:
wireshark -k -i <(ssh <IP> "sudo dumpcap -P -w - -f 'not tcp port 22'")

I don’t use Wireshark enough to be fluent, so here are some links and quotes that proved to be useful for me:

I hadn’t done a lot with pfSense in the past, which I regret a bit since I discovered this really cool feature: Sniffers, Packet Capture – PFSenseDocs.
The coolness isn’t so much that you can capture packets, but that it’s compatible with tcpdump and WiresharkĀ (which has become available natively for Mac like 2 years ago).
Which means that you can download captures and open them in Wireshark.
So it’s as easy as 1,2,3:
- Set-up the capture on your routerĀ https://a.b.c.d/diag_packet_capture.phpĀ and start it
- Stop the capture and download the file
- Open the file in WiresharkĀ or convert it to text using tshark
