Advanced Call Handling

When end-to-end secure media is established through the Secure Real-Time Transfer Protocol (SRTP) and the call status is secure, the phone plays the secure indication tone (three long beeps with brief pauses).

When end-to-end nonsecure media is established through the Real-Time Protocol (RTP) and the call status is nonsecure, the phone plays the nonsecure indication tone (six short beeps with brief pauses).

If the Play Secure Indication Tone option is disabled (False), no tone is played.

Nonprotected call—The phone does not have a “Protected Device” status in Unified CM. No secure or nonsecure indication tone is played.

Nonsecure call—The phone is not protected on the Unified CM server and the call status is nonsecure.

For more information, see your system administrator.

Your system administrator also configures the VPN Client feature as needed. If it is enabled and the VPN Client mode is enabled on the phone, you are prompted for your credentials as follows:

If your phone is located outside the corporate network—You are prompted at login to enter your credentials based on the authentication method that your system administrator configured on your phone.

If your phone is located inside the corporate network—

If Auto Network Detection is disabled, you are prompted for credentials, and a VPN connection is possible.

If Auto Network Detection is enabled, you cannot connect through VPN so you are not prompted.

To access the VPN Configuration settings, press the Settings button and choose Security Configuration

>VPN Configuration.

After the phone starts up and the VPN Login screen appears, enter your credentials based on the configured authentication method:

Username and password—Enter your username and the password that your system administrator gave you.

Password and certificate—Enter the password that your system administrator gave you. Your username is derived from the certificate.

Certificate—If the phone uses only a certificate for authentication, you do not need enter authentication data. The VPN Login screen displays the status of the phone attempting the VPN connection.
