The CRL with revoked server certificate needs to be loaded in the sip client. TLS server
doesn’t send CRL to client during handshake.

Hello,
haven't played with CRL lately, but kamailio should just call libssl functions for
validating the certificates, after initializing the context with CRL file.
Maybe you can open an issue on
github.com/kamailio/kamailio tracker, add there all log
messages printed by kamailio with debug=3 in kamailio.cfg. In this way we do not forget
about it and can be investigated properly.
Cheers,
Daniel

Hi All,
I'm trying to configured kamailio as TLS server with below configuration (tls.cfg)
and TLS server is started successfully.
[server:default]
method = TLSv1+
verify_certificate = yes
require_certificate = yes
private_key = ./sip/server.key
certificate = ./sip/server.crt
ca_list = ./bundle.crt
crl = ./sip_crl.pem
verify_depth = 9
[client:default]
verify_certificate = no
require_certificate = no
TLS connection works fine.
Later i have updated the sip_crl.pem with server certificate revoked details and
performed tls.reload command to load the latest update.
After this I expect any TLS client trying to establish TLS connection should fail, as the
client and server certificates are signed by same authority and server certificate is
revoked. But the clients are able to establish TLS connection without any errors.
I'm not getting any traces to confirm CRL validation has been performed before
accepting the TLS connection.
Any advice would be help to proceed with evaluating CRL functionality.
