Hello,
you add two $xavp(tls=>...) with the operations you do, change to:
$xavp(tls=>server_name)="btip.176.com"; $xavp(tls[0]=>server_id)="btip.176.com";
so the server_id is added to the existing $xavp(tls->...) instead of creating a new one that doesn have server_name.
Cheers, Daniel

Hi , I further went thru the logs of kamailio, and i see the below happening.
tls [tls_server.c:169]: tls_get_connect_server_name[]: xavp with outbound server name not found tls [tls_server.c:152]: tls_get_connect_server_id[]: found xavp with outbound server id: btip.176.com http://btip.176.com
Its strange its able to find the client profile based on server_id , but not able to find using the server_name
In tls_complete_init( )
if (c->flags & F_CONN_PASSIVE) { state=S_TLS_ACCEPTING; dom = tls_lookup_cfg(cfg, TLS_DOMAIN_SRV, &c->rcv.dst_ip, c->rcv.dst_port, 0, 0); } else { state=S_TLS_CONNECTING; sname = tls_get_connect_server_name(); srvid = tls_get_connect_server_id(); dom = tls_lookup_cfg(cfg, TLS_DOMAIN_CLI, &c->rcv.dst_ip, c->rcv.dst_port, sname, srvid); }
Am acting as client, so it will hit the else part
the call to sname = tls_get_connect_server_name(); //failed with below logs tls [tls_server.c:169]: tls_get_connect_server_name[]: xavp with outbound server name not found
the call to srvid = tls_get_connect_server_id(); // success with below logs tls [tls_server.c:152]: tls_get_connect_server_id[]: found xavp with outbound server id: btip.176.com http://btip.176.com
And futher down in the function : as sname is NULL, it is not setting the server name extension in client hello message.
#ifndef OPENSSL_NO_TLSEXT if (sname!=NULL) { if(!SSL_set_tlsext_host_name(data->ssl, sname->s)) { if (data->ssl) SSL_free(data->ssl); if (data->rwbio) BIO_free(data->rwbio); goto error; } LM_DBG("outbound TLS server name set to: %s\n", sname->s); } #endif
Am i missing anything here w.r.t configuration ? or is it a bug ? which has been fixed in later versions ? Please help !!
