Dear Sir,

We are trying to connect a Grandstream Handy Tone 503 with Opensips 1.6.4
using TLS, and are having difficulties.
Our opensips settings are as follows:

disable_tls = no
listen = tls:x.x.x.x:300
tls_verify_server = 0
tls_verify_client = 1
tls_require_client_certificate = 0
#tls_method = TLSv1
tls_method=sslv3
tls_certificate = "/usr/etc/opensips/tls/user/user-cert.pem"
tls_private_key = "/usr/etc/opensips/tls/user/user-privkey.pem"
tls_ca_list = "/usr/etc/opensips/tls/user/user-calist.pem"

The error message we get on opensips is as follows:

 Jul 21 15:58:42 techdata opensips[16153]:
ERROR:core:tls_accept: some error in SSL (ret=0, err=1, errno=0/Success):
Jul 21 15:58:42 techdata opensips[16153]:
ERROR:core:tls_print_errstack: error:14094410SSL
routinesSSL3_READ_BYTESSslv3 alert handshake failure

Blink softphone works with this Opensips config in TLS mode
In ATA 503, we have SIP Transfer as TLS

Best rergards
