[Kamailio-Users] Error in Registration with TLS on

Dear friends, Since last few days i am working on Kamailio with TLS support. I had followed each and every steps in installation docs...created certificates as well. Then i started testing the server with TLS on using SIPP. First i didnt added any certificate to SIPP, and Registration wasnt happening... When i added a certificate and key to SIPP....it started working fine....i was been able to test Registrations Successfully. Then i started working with one open source soft phone supporting TLS named mumble. IT Supports. Now i hadnt added any certificate to Mumblem. In my settings of kamailio i have set clietn_verify = 0 and require_client_certificate = 0. So without certificate as well i should be able to Authenticate my self successfully. Instead it gives following error in kamailio log: Feb 22 09:50:51 localhost ./sbin/kamailio[3300]: DBG:core:print_ip: tcpconn_new: new tcp connection to: 172.16.16.218 Feb 22 09:50:51 localhost

[9:50 AM] Server connection failed: Error during SSL handshake: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure. [9:51 AM] Reconnecting.

[9:51 AM] Server connection failed: Error during SSL handshake: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure. Can any one suggest what could be the problem? My Server works great with SIPP with TLS....so i dont think theres any config related error and i have set client_require_certificate = 0 thats for sure.... In real life scenario, hard or soft phones wont have certificates...so they should be able to connect to server and authenticate/Authorize themselves if server has valid certificate.But its not happening. So i need help from experienced guys.... -- Regards, Hemanshu Patel M: 09601295238
