[SR-Users] [4.2] how to send out BYE successfully to close a TCP/TLS connection which misses the connection ID?

[Jack Wang]

For some reasons,
My settings will cause kamailio to be restarted even if there were
connections connected to it.
And when one SIP client in a connection wanted to hangup the call with a
WebRTC Client (SIP over websocket) after the proxy-restarting,
local client was closed, however , the other side was not.
>From the log below it seems that the connection missed.

Jan 30 18:19:31 ./kamailio[27857]: WARNING: <core> [msg_translator.c:2777]:
via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found
Jan 30 18:19:31 ./kamailio[27857]: ERROR: tm [t_msgbuilder.c:1365]:
assemble_via(): assemble_via: via building failed
Jan 30 18:19:31 ./kamailio[27857]: ERROR: tm [t_msgbuilder.c:1545]:
build_uac_req(): build_uac_req(): Error while assembling Via
Jan 30 18:19:31 ./kamailio[27857]: ERROR: tm [uac.c:379]: t_uac_prepare():
t_uac: Error while building message

So,
Is it equivalent to connection ID missing?
And is there any way to make Websocket  found the connection?

Btw, after proxy-restarting for seconds , I typed `sh kamctl stats` :

websocket:ws_current_connections = 1

It showed that the WebRTC Client will re-connect automatically,
So I think this connection could be found by proxy,
Any suggestion?



Thanks :)
