Hi I used freeswitch on centos 6 . I downloaded freeswitch from “git clone https://freeswitch.org/stash/scm/fs/freeswitch.git And configure properly without errors Then I try to configure mod_verto , https://freeswitch.org/confluence/display/FREESWITCH/mod_verto First I compile the module and then I did configurations from mentioned link below, But I couldn’t create ssl certificate from that instructions Then I used following command to create the certificate and key openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /usr/local/freeswitch/certs/wss.key -out /usr/local/freeswitch/certs/wss.crt cat wss.crt wss.key > /usr/local/freeswitch/certs/wss.pem cat wss.crt > /usr/local/freeswitch/tls/dtls-srtp.crt then I changed ssl.conf file (/etc/httpd/conf.d/ssl.conf) as follows ServerName myserverip:443 SSLEngine on SSLCertificateFile /usr/local/freeswitch/certs/wss.crt SSLCertificateKeyFile /usr/local/freeswitch/certs/wss.key Then restarted httpd server Get the firefox and put https:// myserverip/verto Ask certificate and after add the certificate Loaded login page but can’t log in freeswitch console print following message 2014-12-02 18:11:40.150201 [INFO] mod_verto.c:3688 192.168.1.195:4870 Client Connect. 2014-12-02 18:11:40.150201 [INFO] mod_verto.c:1827 192.168.1.195:4870 Starting client thread. 2014-12-02 18:11:41.169676 [DEBUG] mod_verto.c:1739 192.168.1.195:4870 WS SETUP FAILED [] 2014-12-02 18:11:41.169676 [INFO] mod_verto.c:1853 192.168.1.195:4870 Ending client thread. 2014-12-02 18:11:41.169676 [INFO] mod_verto.c:1860 192.168.1.195:4870 Thread ended Kindly help me to configure this thankyou ach
