appears on the other
party’s row on your graphic display. You can opt to have
voice connections that are no longer secure indicated
by a brief alerting tone and a window with the message
"Unencrypted call" (see
Æ page 110).
Answering a call
Your OpenStage phone rings with the tone signal set
when an incoming call is received. The call is also visu-
ally signaled on the call display.
If transmitted, calling party information (name, phone
number) appears on the display.
Please read carefully the introductory chapter
"Getting to know your OpenStage phone"
Æ page 11 before performing any of the steps
described here on your phone.
1. Closed for secure or open for nonsecure voice communication
If you have set a pattern melody Æ page 107 or a
ringtone Æ page 107 on your phone, it is possi-
ble that service personnel preset a different ring-
tone or deactivates the ringtone, regardless of
the call type (e.g. an external or internal call).
An incoming call will interrupt any ongoing tele-
phone setting operations. When the call ends,
you can press the
N key to return to the point
in the menu structure where you were interrupt-
ed.
