Hi Guys,

Thanks for replying.

@Ludovic: Are you referring to this:

Browser >> WSS >> HA Proxy >>> *WS* >> Kamailio ?

I am trying to have minimum translation between HAproxy and Kamailio so keeping it same. Just want it work then can decide on above.

@Gonzalo: Using public certs. When used only with Kamailio and any WebRTC2SIP client like JsSIP/SIP.js/SIPml5 calls work fine.

Do you guys see anything wrong in HA Proxy Configs, as that part is new to me. Where else should I look? One more info:

JsSIP is hosted on - some-other-domain with Apache on it. And the HA Proxy is hosted on another server with it's cert, hosting wss port and then load-balancing it to Kamailio web-sockets having same certs as HA Proxy (as they are public and for whole domain)

Are you using self-signed certs? or public certs signed by public CA.

Hi,

It might be a stupid question, but why you don't have WebSockets without TLS between HAProxy and Kamailio ? I've a similar setup to enable us to have on the same 443 port regular Web server and SIP WebSockets, for now, it works pretty well.

Hi Guys,

I am trying to setup the following flow:

Browser >> WSS >> HA Proxy >>> WSS >> Kamailio

But getting TLS errors in Kamailio logs: *[29634]: ERROR: <core> [tcp_read.c:1321]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7f68ebe872b0 r: 0x7f68ebe87330* *[29631]: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number*

Browser <-----wss---->Kamailio works fine with same certs.

Both HA Proxy and Kamilio are installed on separate servers, hosting on same port with different domain. Kamailio tls.conf has method = TLSv1

*@HA Proxy:*

openssl s_client -connect HA-PROXY-DOMAIN:*10443*

SSL-Session: Protocol : TLSv1.2

*@Kamailio :* openssl s_client -connect KAMAILIO-DOMAIN:*10443*

SSL-Session: Protocol : TLSv1

So I made HA Proxy to be on TLSv1 "ssl-default-bind-options force-tlsv10" But still I get the same TLS error in Kamailio.

*HA Proxy config looks like:*

*frontend public*

• bind *:10443 ssl crt /etc/haproxy/certs/cert.pem*
• acl is_websocket hdr_end(host) -i m1.some-domain.com

http://m1.some-domain.com*

• use_backend wss if is_websocket*
• default_backend wss*

*backend wss*

• timeout server 600s*
• server ws1 k1.some-domain.com:10443 http://k1.some-domain.com:10443*
• server ws1 k2.some-domain.com:10443 http://k2.some-domain.com:10443*

Need some direction, thanks in advance.

Regards, Jade
