<tt>Hi, Mikhail!<br>
<br>
Unfortunately there is no way for OpenSIPS to recover TCP
connections to the browser. You'll have to modify your sip.js
client to automatically try to reconnect when the connection with
OpenSIPS goes down.<br>
<br>
Best regards,<br>

<div>I am using opensips 2.2.3 to handle websocket connections

<div>Assume I have a call between 2 webrtc clients and I restart
opensips during this call. Media handled by freeswitch, so

<div>Then, one client send BYE. I use loose_route to find

<div>But here I got error that I could not handle.</div>
<div>t_on_failure trigger does not fire</div>
<div>t_relay return success.<br>
