I am trying to enable TLS in FreeSWITCH.

I want an enterprise SIP B2BUA (TLS client) to connect to the FreeSWITCH (TLS server) over TLS. I followed the instructions below and could enable TLS at FreeSWITCH.

However, I see the certificate exchange fails. My enterprise SIP B2BUA seems to send FIN on receiving the certificate from the FreeSWITCH. I imported the cafile.pem into my  enterprise SIP B2BUA server. 

Is there anything that am missing ?

Thanks
