Hi, it is recommended to enable multi-process mode in the config-file for an adequate function of OpenSER with TLS (fork=yes). Your log shows that OpenSER is not able to open the Socket for TLS, which is, as far as I know, due to the fact that no child process could have been started for that socket. Btw: Last year I set up an environment with MiniSIP as well where everything worked well, referring to the descriptions in the TLS-tutorial. Regards PC fengbin schrieb: Hi,all I met a strange problem while I am testing TLS connection between minisip and openser. The following is my openser.cfg (part of that) ......... fork=no log_stderror=yes # Uncomment this to prevent the blacklisting of temporary not available destinations #disable_dns_blacklist=yes # # Uncomment this to prevent the IPv6 lookup after v4 dns lookup failures #dns_try_ipv6=no # uncomment the following lines for TLS support disable_tls = 0 listen = tls:10.11.57.197:5060 tls_verify_client = 1 tls_method = TLSv1 tls_certificate = "/usr/local/etc/openser//tls/user/user- cert.pem" tls_private_key = "/usr/local/etc/openser//tls/user/user-privkey.pem" tls_ca_list = "/usr/local/etc/openser//tls/user/user-calist.pem" tls_ciphers_list="NULL-SHA:NULL-MD5:AES256-SHA:AES128-SHA" ...... When I set "tls:10.11.57.197:5061" the registration never succeed. But if I set it to 5060 the registration over TLS is OK. I compared the log of two scenarioes and found the TLS session both are OK,but the difference is that: when the port is 5061 there is an error of forwarding. but the forwarding is because openser think it's not the destination of the registration request.

Its a little bit strange that when I set the port to 5061,why did openser check the port 5060????? Can anyone help me to figure it out?

Can you show us the REGISTER request? (both, port 5060 and port 5061). Further show use your openser config regards klaus fengbin schrieb: " flags=ffffffffffffffff flags=ffffffffffffffff found flags=ffffffffffffffff flags=ffffffffffffffff
