7.2.2.2 Receiving a Call When Encryption is Always On or Never On
If your ZIP4x4 is configured so that encryption is always on and it receives a call from a device
that has encryption always on , or if your ZIP4x4 is configured so that encryption is always off
and it receives a call from a device that has encryption always off , your phone will answer the
call. The phone turns on the LED on the Encrypt button if encryption is engaged.
If your ZIP4x4 is configured so that encryption is
always on and it receives a call from a device
that has encryption always off , or if your ZIP4x4 is configured so that encryption is always off
and it receives a call from a device that has encryption always on , your phone will reject the call.
The phone does not make any sound or light any LEDs. Your phone accumulates this as a missed
call (see section 8.4.4.3 on page 88). You can identify that the call was rejected as described in
section 8.7.5 on page 98.
7.2.2.3 Making a Call With Encryption Normally On or Normally Off
When you enable encryption on the phone, it functions on each line independently. Therefore
you can have an encrypted call with a person on one call appearance and a call that is not
encrypted with another person on a different call appearance.
To encrypt a call prior to dialling:
•
If the phone is configured so that encryption is normally off , press a free call appearance
button then press the encrypt button.
•
If the phone is configured so that encryption is normally on , as soon as you start to make a call
the phone enables encryption.
The phone flashes the LED on the call appearance button green and also flashes the LED on the
Encrypt button synchronously. Dial the number using any of the methods that you can use for a
call that is not encrypted.
To encrypt a call that is already established, press the Encrypt button during the conversation.
If the other person’s phone can accept encrypted voice the ZIP4x4 lights the LED on the Encrypt
button solid green but makes no change to the display.
If the far end phone rejects the request to enable encryption, your ZIP4x4 beeps three times
through the audio channel you are using, and displays:
The phone holds this display for two seconds, until you press a key, or go on hook.
7.2.2.4 Answering a Call With Encryption Normally On or Normally Off
Your phone automatically configures itself to engage or not engage encryption depending on the
request from the calling device. Your phone makes no sound and makes no change to the LCD.
It lights the LED on the Encrypt button continuously green if encryption is engaged.
Warning:
Encryption turned
off by far end.
