Parameter Description
SRTP Setting
Media Security
[EnableMediaSecurity]
Enables Secure Real-Time Transport Protocol (SRTP).
 [0] Disable = SRTP is disabled (default).
 [1] Enable = SRTP is enabled.
Media Security Behavior
[MediaSecurityBehaviour]
Determines the device's mode of operation when SRTP is used
(EnableMediaSecurity = 1).
 [0] Preferable = The device initiates encrypted calls. If negotiation
of the cipher suite fails, an unencrypted call is established.
Incoming calls that don't include encryption information are
accepted.
 [1] Mandatory = The device initiates encrypted calls, but if
negotiation of the cipher suite fails, the call is terminated. Incoming
calls that don't include encryption information are rejected
(default).
IPSec Setting
Enable IP Security
[EnableIPSec]
Enables / disables the Internet Protocol security (IPSec) on the
device.
 [0] Disable = IPSec is disabled (default).
 [1] Enable = IPSec is enabled.
Dead Peer Detection Mode
[IPSecDPDMode]
Enables the Dead Peer Detection (DPD) 'keep-alive' mechanism
(according to RFC 3706) to detect loss of peer connectivity.
 [0] Disabled (default).
 [1] Periodic = message exchanges at regular intervals.
 [2] On Demand = message exchanges as needed (i.e., before
sending data to the peer). If the liveliness of the peer is
questionable, the device sends a DPD message to query the
status of the peer. If the device has no traffic to send, it never
sends a DPD message.
For detailed information on DPD, refer to the Product Reference
Manual.
