Hi,
I have a WebRTC softphone based on JsSIP and kamailio 4.4.7. Generally it
works well but sometimes websocket connections interrupt and reconnect
immediately (especially running behind proxies). If the interruption occurs
during an active call, kamailio tries to send BYE message to softphone over
closed websocket.
gruu_enabled flag is active on registrar module and JsSIP sends proper
sip.instance value. So after ws reconnects, registered contact details do
not change on kamailio except Expires value.
Is it possible to send BYE message via contact's last active websocket
after reconnect?
