TLS Handshake failure

I’m working on TLS and SRTP on asterisk. I create self-signed certificates for my server .

I managed to connect two clients with Zoiper without problem in server’s logs. But when I tried with a my mobile phone I can observ this warning which don’t allow a good TLS session :

  > Saved useragent "CSipSimple_m0-16/r2330" for peer tete

SSL certificate ok
== Problem setting up ssl connection: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
[May 26 14:30:27] WARNING[15187]: tcptls.c:274 handle_tcptls_connection: FILE * open failed!
(PS : “tete” is the name of user account and “CSipSimple” is my softphone)

I don’t know what is the problem because the others clients can communicate without problem with TLS and SRTP.

Any suggestions would be appreciated.
