Essentially: Normal Encoding, > *Encryption*, Sending, Receiving, *Decryption*, Decoding, etc. Daniel, There are a couple of different places where encryption is (can be) done in sipXtapi - one is completed and working, while the other has some plumbing, but not an actual implementation. For signaling, there is an implementation of SIP message encryption (it uses Mozilla NSS for transport of SIP messages over TLS, and for S/MIME encoding of sdp bodies. The sdp bodies need to be encrypted if SRTP is to be used - SRTP is using a shared secret passed along as an SDP attribute (see SdpBody::addSrtpCryptoField). So, this brings me to the other security feature - media encryption with SRTP. There is plumbing to get the appropriate Srtp key info down to the media layer, but, as far as I know, there is no actual srtp encryption/decryption done (although, there may be plans to add this to the media-update branch, or it may already be there - I don't know.) A quick grep of the source for 'srtp' will point you to the srtp plumbing,
