Hello list,
I have kamailio 5.5.3 (x86_64/linux) configured as an SBC in front of asterisk to front
end webrtc clients. Browser clients running JsSIP 3.7.0 connect to kamailio via webrtc and
kamailio sends the traffic back to asterisk using SIP. rtpengine is configured to relay
the RTP packets.
I need to send websocket pings every 10 seconds to the browser clients.
I have the following config in kamailio:
modparam("websocket", "keepalive_mechanism", 1)
modparam("websocket", "keepalive_timeout", 10)
modparam("websocket", "keepalive_interval", 2)
modparam("websocket", "keepalive_processes", 2)
modparam("websocket", "verbose_list", 1)
If my understanding of the documentation is correct, I do not need to do any additional
configuration.
But looking at the websocket traffic, I do not see any ping packets in websocket. I am
also using sipdump module to capture all packets sent and received by kamailio and the
ping packets are not visible there either.
What could be wrong here? Do I need to do any additional config?
Thanks for every help!

Xuo,
How do you capture this traffic? WebSocket pings is not an ordinary
"SIP-style OPTIONS" pings, It's packets described in RFC6455 -
https://datatracker.ietf.org/doc/html/rfc6455#section-5.5.2

Hi,
Yes, I understand that the SIP OPTIONS and websocket pings are different.
I check the ping using two methods. One at the client side using chrome developer tools.
At the server side I use sipdump module to capture all traffic.
modparam("sipdump", "enable", 1)
modparam("sipdump", "folder", "/var/log/kamailio/sip/")
With this enabled, kamailio dumps all the traffic in a file for analysis. For example:
tag: rcv
pid: 1553531
process: 16
time: 1646982958.357033
date: Fri Mar 11 12:45:58 2022

I expect the ping websockets to be printed here, but this is not the only place I am

my case neither place shows any trace of websocket pings packets.

Xuo,
Can't say for Chrome Web Tools, but they most likely will filter these
packets out as they are not part of "real traffic". I'd suggest you to do a
capture directly on the wire with Wireshark or so.
Same for Kamailio, I also don't expect em to be saved there for the same
reason above.

Indeed, the sipdump is not saving everything that comes in or goes out
of kamailio, only the traffic that uses the functions for handling or
sending sip traffic. http is mapped over sip internally, but ws pings
are using directly lower api for tcp send.

Daniel

Thanks for your inputs Daniel and Igor.
I have confirmed that Kamailio is indeed sending out WebSocket ping as configured.
Chrome's network tab do not show the control packets, but it can be viewed using
firefox.
