User's Manual
Global parameter that defines the size (in bytes) of the Master Key
Identifier (MKI) in SRTP Tx packets. You can also configure this
functionality per specific calls, using IP Profiles
(IpProfile_MKISize). For a detailed description of this parameter
and for configuring this functionality in the IP Profile table, see
''Configuring IP Profiles'' on page 314.
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.
Global parameter that enables symmetric MKI negotiation. You can
also configure this functionality per specific calls, using IP Profiles
(IpProfile_EnableSymmetricMKI). For a detailed description of this
parameter and for configuring this functionality in the IP Profile
table, see ''Configuring IP Profiles'' on page 314.
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.
Defines the offered crypto suites (cipher encryption algorithms) for
SRTP.

[0] All = (Default) All available crypto suites.

[1] 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] 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] 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] 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.
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.
