[SR-Users] Implementing encryption

[Techie Sup]

Hello,

This was a concept raised in my mind and was looking for a lead or
hint to get started to work on routing rtp via tcp. ( On SIP phone as
well as Kamailio ). I knew through googling there has been such
implementation and thus to make sure it is an absolute possibility. So
here, I am just trying my luck to interact with developers who has
worked on such project, if any.

Warm Regards
Selvam
