Subject: [SIPForum-discussion] Encryption of media stream


Hi all
 
How does SIP provide encryption for the RTP/RTCP media stream? There is
a k= option in SDP, but it says (even in the IETF docs) that its not a
great option and its not to be used. How can two parties agree upon an
encryption method and key?
 
Same question for H.323, but I guess it's not the right place here.
 
Thnx in advance
