Hi Daniel
I’m testing with a Yealink T57W. It comes with a factory install certificate which will probably fail validation as the common name is the MAC.
I'm not trying validate the client device’s certificate just get it to offer what it has so I can check the details.
Thanks Mark

Hello,
what is the SIP client app you used? Is it configured to use its own tls certificate when connecting to the SIP server?

Hi all
Been trying to grab the TLS cert details from incoming connections, but failing :-(
So with lines just before AUTH is called like this;
if (proto == TLS) { xlog("L_INFO", "TLSDUMP $ci peer_subject : $tls_peer_subject\n");Gets met with a log line line this;
INFO: tls [tls_server.c:431]: tls_accept(): tls_accept: new connection from 1.2.3.4:11797 using TLSv1.2 ECDHE-RSA-AES256-GCM-SHA384 256 INFO: tls [tls_server.c:434]: tls_accept(): tls_accept: local socket: 5.6.7.8:5061 INFO: tls [tls_server.c:445]: tls_accept(): tls_accept: client did not present a certificate ... INFO: tls [tls_select.c:168]: get_cert(): Unable to retrieve peer TLS certificate from SSL structure
This is with verify_certificate and require_certificate set to no in tls.cfg
If I try and set the following in tls.cfg
[server:default] method = TLSv1.2+ verify_certificate = no require_certificate = yes
I see in the logs;

ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1417C086:SSL routines:tls_process_client_certificate:certificate verify failed
Which looks like verification is being enabled when I add require?
Would someone be kind enough to point out what I am missing please? (Assuming it’s not a bug :-)
