The Media Encryption field is displayed on the IP Media Parameters screen only when:
The Media Encryption over IP feature is enabled in the license file.
The Media Encryption over IP feature is displayed as y on the Customer Options screen.
If the Media Encryption Over IP? field is set to n, the Media Encryption field on the IP Media Parameters screen is hidden and functions as if none is selected.
About this task
On the IP Media Parameters screen, you can administer the type of media encryption, if any, for each codec set.
Note:
H.323 endpoints do not require any encryption administration, and end users need not do anything to use media encryption

Procedure
On the SAT screen, type any of the following and press Enter:
change ip-codec-setnumber
change ip-media-parametersnumber
The system displays the IP Media Parameters screen.
Enter up to three media encryption types.
The Media Encryption field specifies one, two, three, four, or five options for the negotiation of encryption. In this exam, you can choose one mode each from SRTP, aes, and aea. You can specify no encryption by entering none in the Media Encryption field. The default value for this field is none. The order in which the options are listed signifies the preference of use, similar to the list of codecs in a codec set. Two endpoints must support at least one common encryption option for a call to be completed between them.
Note:
The option that you select in the Media Encryption field for each codec set applies to all codecs defined in the set.
