[SR-Users] WSS connection is getting dropped after BYE is sent

Hi,
I have successfully configured Kamailio for WSS support using the below instructions. Everything works perfectly except, when call is hanged up from the receiving end, Kamailio sends BYE and the browser disconnects websocket connection right after getting response from Kamailio with the following error message:
Firefox: WebSocket connection to 'ws://localhost:3001/websocket' failed: Invalid frame headerChrome: The connection to ws://localhost:3001/websocket was interrupted while the page was loading.
Everything works perfectly over plain websocket(WS). Kamailio is sending something with the websocket that the browsers do not like. But im not sure what it is. If somebody faced same issue before or can give any clue that would be really helpful.
Thanks in advanced!

Hi Ben,
In regards your certificates, please double check the following:a) CN field:In your webrtc client check the URL used for wss. and verify it matches the CN field of the certificate installed in kamailio:Example:In my sipml5 client I configured wss://ramenlabs.io:5063 and my certificate in fact contains in the cn field ramenlabs.io
Subject: OU=Domain Control Validated, OU=PositiveSSL, CN=ramenlabs.io
openssl x509 -in /etc/certs/sip.192.168.146.133/cert.pem -noout -text
b) I have successfully configured Kamailio 4.1 with TLS and WSS using TLS port 5063Topology:1) sipml5 --wss--> ngnix -wss-> kamailio (sip registrar)2) sipml5 --wss---> kamailio

ok. I have made some changes. rather than getting the TLS configaration from a file I added this lines:

now, Im getting different logs which looks good. Getting positive results from openssl test,
openssl s_client -connect 192.168.146.133:5061 -tls1CONNECTED(00000003)^C
But when I try to connect using my webRTC client or even from web-browsers im getting timed out. I think im close .. please help me fixing this issue.

Out of curiosity, why don't you use the pre-built packaged binaries instead of building from source?

Hi,
Im trying to connect my WebRTC clietn
to kamailio via WSS. I successfully connected it via WS but having
trouble connecting it via WSS. My first issue is I get error messages
while i try to compile TLS module(console log in the end of the
document). But, still it creates tls.so file. So i copied the tls.so
to my kamailio modules directory and then updated my kamailio
configuration as below:
#!define WITH_TLS
.
.
listen=tcp:127.0.0.1:5061
listen=tcp:192.168.146.133:5061
.
.
#!ifdef WITH_TLS
enable_tls=yes
#!endif
.
.
#!ifdef WITH_TLS
# ----- tls params -----
modparam("tls", "config",
"/usr/local/kamailio-devel/etc/kamailio/tls.cfg")
#!endif
Now, according to this mailing
list,http://lists.sip-router.org/pipermail/sr-users/2013-March/077182.html
: “when
tls module is installed, a self signed pair of certificate-private
key is generated in /usr/local/etc/kamailio”
In
my case, I dont even have the /usr/local/etc/kamailio directory. So,
I followed
http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates
to create my certificate and key. And updated my tsl.cfg, this is how
my tsl.cfg looks like:
[server:192.168.146.133:5061]
method
= TLSv1
verify_certificate
= no
require_certificate
= no
private_key
= /etc/certs/sip.192.168.146.133/key.pem
certificate
= /etc/certs/sip.192.168.146.133/cert.pem
ca_list
= /etc/certs/demoCA/cert.pem
[client:192.168.146.133:5061]
verify_certificate
= yes
require_certificate
= yes
Then I restarted my kamailio server.
And i get the following errors in my kamailio log:
Im not sure what wrong im doing. Please
help me:
