Hello,

wss is not usually on port 5060, it can be on port 5061 (if you haven't configured another tls socket specially for wss traffic). Anyhow, wss traffic is encrypted, so sngrep will not match it as sip traffic.

If you want to see locally the wss sip traffic, load sipdump module, it will write in text files (the version in master can save the traffic in pcap files as well, although it will appear as being udp traffic, because it was simpler to build the pcap headers, however you can sport from the headers/ports what was the trasport layer, or enable to add the extra meta-data sip header).

If you already have homer, then you should see the wss encrypted traffic there.

Cheers,
Daniel

Hmmmm seeing that port 127.0.0.1….9060  looks like to capture and forward  to homer (I know I installed it at one time to try to some triage).

Maybe homer built for additional checks.
I just disabled the module hosting that port and I no longer see it in ngrep.

 my path  issue is  wss://  webrtc over to  uac.reg and FW it  off  to  PBX. So ill try  and  figure out where  in kama.cfg to hopefully get  it to fw to pbx  and make call.

Ya I have other  scenarios  that show  up  like  inbound call.

So I did this (made a test call)  and saved output ngrep to pcap.

And open in wireshark  and I see it as protocol  UDP  with SIP enclosed  in data

ngrep -d any -qt -W byline port 5060 -O test.pcap

heres ngrep

You sure you’re using 5060 on kamailio?

Are you using vlans? In the past I had issues with ngrep if the packets had vlan tags on them.

I can see kama logs./ngrep when I try to call out (WSS -> ) . But I cant see anything in sngrep nor tcpdump.

“ngrep -d any -qt -W byline port 5060”

Im not sure how/why or  it could be something simple but what puzzles me is I know im sending data but its not captured.

Setup is pbx at 24.xx.xx.xx but ext is uac.reg to stay connected.

UA client  = sip.js / wss

Inbound works(but  1 way  audio ill fix after outbound issue)

Outbound doesn’t dial out  (UA = webRTC client) using wss. Which led  me to troubleshoot  via  sngrep/tcpdump.

But I seet his when  it happens knowing I ame getting  something  sent.
