I know that FreeSWITCH supports ZRTP but I would like to know if someone already tried to deploy SRTP on FreeSWITCH? If so, can I have the HOWTO describing this setup if any have been done?
I tried it, but it exposed bugs in OpenSSL. Soon thereafter, ZRTP became available so I switched to that. If you want SRTP, you have to turn on TLS, make sure that both ends are using it, and enable SRTP in the SIP profile, if I remember correctly. ZRTP is better in my opinion; the only reason why you would want to use SRTP is for interoperability with end-points that support it, but not ZRTP - unless you have a public-key infrastructure in place that you want to use for some reason.
