SRTP. It can be selected from dropdown list:
• AES128&256 bit
• AES 128 bit

If it is set to “AES 128&256 bit”, the phone system will provide both AES
128 and 256 cipher suite for SRTP. If set to “AES 128 bit”, it only provides
128-bit cipher suite; if set to “AES 256 bit”, it only provides 256-bit cipher
suite. The default setting is “AES128&256 bit”.
