Secure Real-Time Transport Protocol (SRTP)
Secure Real-Time Transport Protocol (SRTP) encrypts the audio streams during VoIP phone calls to avoid inter-
ception and eavesdropping. The parties participating in the call must enable SRTP feature simultaneously. When
this feature is enabled on both phones, the type of encryption to use for the session is negotiated between the
phones. This negotiation process is compliant with
RFC 4568 .
When you place a call on the enabled SRTP phone, the phone sends an INVITE message with the RTP/RTCP
encryption algorithm to the destination phone. As described in
RFC 3711 , RTP/RTCP streams may be encrypted
using an AES (Advanced Encryption Standard) algorithm.
Example of the RTP encryption algorithm carried in the SDP of the INVITE message:
