Hello,
are the endpoints connecting directly to Kamailio, or is there a http
proxy/tcp loadbalancer in front?
It is pretty unlikely another endpoint to get same source ip and port,
unless is a middle proxy that reuses the connection. I met the latter
case in the past, but not the former.
Cheers,
Daniel

Hi,
The proxy-ws has no way of knowing which client is registered; all
it can do is consume the RURI as received, and map it to an
existing connection from IP1:PORT1.
I think it's vital to get to the bottom of why the first
connection was never "cleaned up". When the socket closes, it
should be cleaned up, and rather immediately. What's going on there?

Hello guys,
We're seeing corner cases where the following happens:
On proxy-ws
- IP1:PORT1 connects via websocket from Client1
- Registration happens on an upstream kamailio
- for any reason, the TCP socket closes or times out.
- IP1:PORT1 (same IP:PORT combination) connects via websocket
from Client2
- Registration happens on an upstream kamailio
Now a call comes in to Client1. Because the first connection was
never cleaned up, it is sent to the proxy-ws and the proxy will
send it to the IP1:PORT1 where Client2 is connected.
Short story, proxy-ws doesn't check the IP1:PORT1 where it is
sending the INVITE is the actual client it is supposed to be
sending...
It seems that when a socket is closed, the mapping IP:PORT to
Address (i.e.: sip:d4f27e34@994f31243be9.invalid;transport=ws)
doesn't seem to be cleared... is this by design?
Thanks!
