For signalling: http://wiki.freeswitch.org/wiki/SIP_TLS For media: http://wiki.freeswitch.org/wiki/SRTP The key used to encrypt the media is passed through the signalling, so you should make sure the signalling is encrypted otherwise everyone will be able to see the key and read the media. -Steve On 4 February 2011 06:44, Dmitry Mordovin <d.mordovin@dwide.com> wrote:

Hello,

I wish to implement some simple encryption stuff into FS.

My Idea: Imagine, some clients who have SIP softphone with encryption (My own method and only SIP signaling packets will affected) will interconnect with FS. So, FS must decrypt this packets before proceed it and encrypt before sent to this client.

Could anyone direct me to easy way to implement it?

Thanks Dmitry
