Description
Global parameter that defines the size (in
bytes) of the Master Key Identifier (MKI)
in SRTP Tx packets. You can also
configure this feature per specific calls,
using IP Profiles (IpProfile_MKISize). For
a detailed description of the parameter
and for configuring this feature in the IP
Profiles table, see Configuring IP
Note: If this feature is configured for a
specific IP Profile, the settings of this
global parameter is ignored for calls
associated with the IP Profile.
