Defines the offered crypto suites (cipher encryption algorithms) for
SRTP.

[0] = All available crypto suites (default)

[1] CIPHER SUITES AES CM 128 HMAC SHA1 80 = device uses
AES-CM encryption with a 128-bit key and HMAC-SHA1 message
authentication with a 80-bit tag.

[2] CIPHER SUITES AES CM 128 HMAC SHA1 32 = device uses
AES-CM encryption with a 128-bit key and HMAC-SHA1 message
authentication with a 32-bit tag.

[4] CIPHER SUITES ARIA CM 128 HMAC SHA1 80 = device uses
ARIA encryption algorithm with a 128-bit key and HMAC-SHA1
message authentication with a 32-bit tag.

[8] CIPHER SUITES ARIA CM 192 HMAC SHA1 80 = device uses
ARIA encryption algorithm with a 192-bit key and HMAC-SHA1
message authentication with a 32-bit tag.
Note: For enabling ARIA encryption, use the AriaProtocolSupport
parameter.
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.

For ARIA encryption of SRTP, the device must be installed with the
relevant Software Upgrade Feature Key.
Enables authentication on transmitted RTP packets in a secured RTP
session.

[0] Enable (default)

[1] Disable
Enables encryption on transmitted RTP packets in a secured RTP
session.

[0] Enable (default)

[1] Disable
Enables encryption on transmitted RTCP packets in a secured RTP
session.

[0] Enable (default)

[1] Disable
