What I wrote in below, is not correct. (1) Pointing Chrome to
https://<sip proxy>:5061 does result in successful handshake: Oct 17 17:53:06 lohi /usr/bin/sip-proxy[13274]: INFO: tls [tls_domain.c:751]: sr_ssl_ctx_info_callback(): SSL handshake started Oct 17 17:53:06 lohi /usr/bin/sip-proxy[13274]: INFO: tls [tls_domain.c:751]: sr_ssl_ctx_info_callback(): SSL handshake started Oct 17 17:53:06 lohi /usr/bin/sip-proxy[13274]: INFO: tls [tls_domain.c:763]: sr_ssl_ctx_info_callback(): SSL handshake done Oct 17 17:53:06 lohi /usr/bin/sip-proxy[13274]: INFO: tls [tls_server.c:431]: tls_accept(): tls_accept: new connection from 192.168.43.159:43874 using TLSv1.3 TLS_AES_256_GCM_SHA384 256 (2) But when JsSIP TryIt app tries to connect to K at the same port, it does not result in SSL handshake done, but a series of trials: Oct 17 17:55:20 lohi /usr/bin/sip-proxy[13274]: INFO: tls [tls_domain.c:751]: sr_ssl_ctx_info_callback(): SSL handshake started Oct 17 17:55:23 lohi /usr/bin/sip-proxy[13274]: INFO: tls [tls_domain.c:751]: sr_ssl_ctx_info_callback(): SSL handshake started Oct 17 17:55:25 lohi /usr/bin/sip-proxy[13274]: INFO: tls [tls_domain.c:751]: sr_ssl_ctx_info_callback(): SSL handshake started ... And if I first do (1), then also (2) succeeds. With Firefox, (2) works without (1). -- Juha _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
