Security
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.
INFO:
If SRTP is enabled, ANAT interworking (see
Media/SDP
)
is only possible if SDES is configured as the key exchange
protocol for SRTP.

3.4.1.3 SDES Configuration
When SDES is selected as SRTP negotiation method (see
Security - General
Configuration
), it can be configured further.
The SDES status parameter enables or disables SDES, just like SRTP type in
System > Security > System (see
Security - General Configuration
). When SDES
is disabled, MIKEY will be used.
The SDP negotiation parameter specifies whether the use of SRTP will be forced
by the phone. The following choices are available:
|
--- Admin
|--- System
|--- Security
|--- Server cerfificate
|--- Use secure calls
|--- SRTP type
|--- Use SRTCP
