Eric,

I think you need to clarify the context of the following statement you 
made: "The reality is that NO ONE has implemented any security to

Certainly, SRTP is widely implemented and deployed in many environements
(e.g., Enteprise telephony for example).

I am assuming that your comment was specific to MRCPv2?
