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.
