3.4.1.2 MIKEY Configuration
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 and Use SRTCP options are only available for secure (encrypted) calls, i.e.
these parameters are only enabled if Use secure calls is activated.
When Use SRTCP is activated (together with Use secure calls), the phone will use SRTCP
(Secure RTCP) to transmit and receive RTP control packets.

For secure (encrypted) calls, it is required that both endpoints support SRTP. The
secure call indication tells the user that the other endpoint has acknowledged the se-
cure connection.
