MIKEY (Multimedia Internet KEYing) is a key management protocol that is intended for use with
real-time applications. It can specifically be used to set up encryption keys for multimedia ses-
sions that are secured using SRTP.
Use secure calls
activates the encryption of outgoing calls, i.e. the phone is capable of receiv-
ing encrypted calls.
The
SRTP type
sets the key exchange method (negotiation method) for secure calls via SRTP.
The following encryption key exchange methods are available:
•
MIKEY
•
SDES (see Section 3.4.1.3, “SDES Configuration”)
The
SRTP Type

(Secure RTCP) to transmit and receive RTP control packets.
