Security
Figure 46: Security icon enabled
Note:
Connecting to the server requires that the IP Deskphone uses, at a minimum,
TLS_RSA_WITH_AES_128_CBC_SHA, and as an objective,
TLS_RSA_WITH_AES_256_CBC_SHA. Because this is a server-specific configuration, the IP
Deskphone must be prepared to handle both. There is no difference in screen indication, regardless
of the type of cipher used.
The following table describes the configurations that affect the presence of the security icon on the
idle screen of the IP Deskphone.
Configuration
Default: UDP + TCP

Unsupported configurations cannot be saved. If the configurations are unsupported, the IP
Deskphone displays an error message.
The following is an example of an error message for unsupported configurations:Unsupported:
