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 !!

Hi, I'm testing the integration of CGRates v0.9.1~rc8 with a copy of Kamailio v5.2.5 already working in production. I'm experiencing several problems when Kamailio and CGRates communicates over evapi and exchanges events via JSON RPCs. Has someone integrated CGRates with Kamailio to build a robust Prepaid System and could then share some information like: - what version of Kamailio\CGRates integrates fine? - relevant part of kamailio.cfg/cgrates.json configuration files? Any other helps is really appreciated. I take this opportunity to wish everyone a Merry Christmas and all the best for 2020.

Hi Sergiu, thanks for your reply. With Kamailio v5.1.9 and CGRateS 0.9.1~rc8 git+fc97b08 (2020-01-02T16:01:14+01:00) all works fine! I'm going to investigate in depth why Kamailio v5.2.5 does not able to correctly parse messages coming from CGRates even if configuration are the same over the two different version. Could you please share the libev and libevent packages installed on your environment? Many thanks in advance.

We have it running in production, can't really share entire snippets of script/config due to our company's policy. # cgr-console --version CGRateS 0.9.1~rc8 git+4030357 (2019-10-10T10:56:04+02:00) # kamailio -v version: kamailio 5.1.9 What challenges are you facing? May be post your troubles here and people will try to help. You must have read it already, there's a Kamailio integration tutorial at https://cgrates.readthedocs.io/en/latest/tut_kamailio.html Cheers.
