Hi all,
I’m still stuck with this even if I built a new VM to avoid any buggy configuration.
Some thoughts on this:
I have tried to change verify_certificate = no on my server section of tls.cfg, so ideally the remote certificate will not be verified, but this is not changing anything.to understand properly, even if you have verify_certificate = no, the certificated is verified and fails?
Otherwise I don't have access to Skype for Business 2015, so I cannot troubleshoot much.
Cheers, Daniel
My Kamailio cluster is part of a DNS alias, but the alias is defined as alias=<myalias>:5061 in the Kamailio.cfg. Could this be affecting somehow the verification? My tls.cfg only has server:default and client:default section.Every time I reload the configuration, the TLS info and debug messages for client and server are coherent with what I would expect from my tls.cfg:INFO: tls [tls_domain.c:278]: fill_missing(): TLSs<default>: tls_method=20 INFO: tls [tls_domain.c:290]: fill_missing(): TLSs<default>: certificate='/usr/local/etc/kamailio/tls/myCert.pem' INFO: tls [tls_domain.c:297]: fill_missing(): TLSs<default>: ca_list='/usr/local/etc/kamailio/tls/myCAfile.pem' INFO: tls [tls_domain.c:304]: fill_missing(): TLSs<default>: crl='(null)' INFO: tls [tls_domain.c:308]: fill_missing(): TLSs<default>: require_certificate=1 INFO: tls [tls_domain.c:315]: fill_missing(): TLSs<default>: cipher_list='(null)' INFO: tls [tls_domain.c:322]: fill_missing(): TLSs<default>: private_key='/usr/local/etc/kamailio/tls/myKey.pem' INFO: tls [tls_domain.c:326]: fill_missing(): TLSs<default>: verify_certificate=1 INFO: tls [tls_domain.c:329]: fill_missing(): TLSs<default>: verify_depth=9 DEBUG: tls [tls_domain.c:968]: fix_domain(): using tls methods range: 20 DEBUG: tls [tls_domain.c:566]: load_crl(): TLSs<default>: No CRL configured INFO: tls [tls_domain.c:658]: set_verification(): TLSs<default>: Client MUST present valid certificate INFO: tls [tls_domain.c:278]: fill_missing(): TLSc<default>: tls_method=20 INFO: tls [tls_domain.c:290]: fill_missing(): TLSc<default>: certificate='/usr/local/etc/kamailio/tls/myCert.pem' INFO: tls [tls_domain.c:297]: fill_missing(): TLSc<default>: ca_list='/usr/local/etc/kamailio/tls/myCAfile.pem' INFO: tls [tls_domain.c:304]: fill_missing(): TLSc<default>: crl='(null)' INFO: tls [tls_domain.c:308]: fill_missing(): TLSc<default>: require_certificate=1 INFO: tls [tls_domain.c:315]: fill_missing(): TLSc<default>: cipher_list='(null)' INFO: tls [tls_domain.c:322]: fill_missing(): TLSc<default>: private_key='/usr/local/etc/kamailio/tls/myKey.pem' INFO: tls [tls_domain.c:326]: fill_missing(): TLSc<default>: verify_certificate=1 INFO: tls [tls_domain.c:329]: fill_missing(): TLSc<default>: verify_depth=9 DEBUG: tls [tls_domain.c:968]: fix_domain(): using tls methods range: 20 DEBUG: tls [tls_domain.c:566]: load_crl(): TLSc<default>: No CRL configured INFO: tls [tls_domain.c:658]: set_verification(): TLSc<default>: Server MUST present valid certificate DEBUG: tls [tls_domain.c:1119]: load_private_key(): TLSs<default>: Key '/usr/local/etc/kamailio/tls/myKey.pem' successfuly loaded DEBUG: tls [tls_domain.c:1119]: load_private_key(): TLSc<default>: Key '/usr/local/etc/kamailio/tls/myKey.pem' successfuly loaded DEBUG: tls [tls_rpc.c:82]: tls_reload(): TLS configuration successfuly loaded
