[Freeswitch-users] Anything which encrypt SIP/SDP messages ?

[Herold Park]

Is there something which encrypt SIP and SDP  in the FreeSWITCH ?
The SIP messages seem to be encryption with AES in FS.
But the SDP doesn't. does it OK?

If it is available, How can i configuration in the FreeSWITCH?

* Any help with this would be greatly appreciated.*
