Notes:

For enabling ARIA encryption, use the AriaProtocolSupport
parameter.

This parameter also affects the selection of the crypto in the
device's answer. For example, if the device receives an offer
with two crypto lines containing HMAC_SHA1_80 and
HMAC_SHA_32, it uses the HMAC_SHA_32 key in its SIP 200
OK response if the parameter is set to 2.
Enables ARIA algorithm cipher encryption for SRTP. This is an
alternative option to the existing support for the AES algorithm.
ARIA is a symmetric key block cipher algorithm standard
developed by the Korean National Security Research Institute.

[0] Disable (default)

[1] Enable
Notes:

To configure the ARIA bit-key encryption size (128 or 192 bit)
with HMAC SHA-1 cryptographic hash function, use the
SRTPofferedSuites parameter.

The ARIA feature is available only if the device is installed with
a Software License Key that includes this feature. To install a
Software License Key, see Software License Key on page 572.
Enables authentication on transmitted RTP packets in a secured
RTP session.

Global parameter that enables synchronization of the SRTP state
between the device and a server when a new SRTP key is
generated upon a SIP session expire. You can also configure this
functionality per specific calls, using IP Profiles
(IpProfile_ResetSRTPStateUponRekey). For a detailed description
of this parameter and for configuring this functionality in the IP
Profile table, see ''Configuring IP Profiles'' on page 304.
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with
the IP Profile.
