does anyone have any idea on the issue below?
Alessio told me that is always reproducible, and he can also provide
captures and more logs.
Thanks in advance!

I have a problem with the blind transfer via WebSocket,
debugging from the browser we see that in some cases when the REFER is
done and the sip message "202 Accepted" arrives,
the message "180 Ringing" arrives first and then the "100 Trying"
and the transfer goes in error with "500 JsSIP Internal Error"
I have an architecture with Kamailio in frontend and asterisk in backend
on the same network, the sip dialogue between FE and BE is in SIP / UDP.
The WebRTC client connects to WebSocket at Kamailio's public address.
We have verified that the sip messages exchanged between kamailio and
asterisk are always correct.
Kamailio Ver. 4.4.4
Asterisk Ver. 13.18.3
PJSIP Ver. 2.6
JSSIP Ver. 3.2.2
