Other Troubleshooting (Including Failover) - Avaya one-X 9600 Series Installation And Maintenance Manual

Troubleshooting Guidelines
When SRTP is provisioned in CM, the default cryptosuite used is 'aescm128-hmac80'. The
9600 Series SIP IP Telephone also assumes that no encryption is an option provisioned in CM.
If these assumptions were made explicit in the 46xxsettings.txt file they would show as:
SET MEDIAENCRYPTION "9"
Again, this is the telephone's default (9 = 'none') and need not be provisioned explicitly in the
46xxsettings.txt file. If some other encryption set is required, the string must be set
appropriately in the 46xxsettings.txt file. For example, to disable encryption, the following line
must be added to the 46xxsettings.txt file:
SET MEDIAENCRYPTION "9"
The setting of 9 corresponds to no encryption.
