G. Calling from mobile GSM CryptoPhones to the CryptoPhone PSTN/1
In order to place a secure call
from a mobile GSM CryptoPhone to a CryptoPhone
PSTN/1
, you must switch the “CSD Line Type” on your mobile GSM CryptoPhone
from "V.110, non-transparent" to "V.32, non-transparent" (if it is not already set to
V.32). For instance:
•
As a CryptoPhone G10i user,
within the CryptoPhone application, press
“Menu”
“Settings” and in the menu that will appear select "Call to: Analog
(V.32) " instead of "GSM/ISDN (v.110)". V.32 may or may not be your
default CSD Line Type depending on your local network environment.
•
As a CryptoPhone 200,220 or CryptoPhone 300 user
, go to Start
Settings
Connections
CSD Line Type to do the same.
Please always refer to the manual that came with your mobile GSM CryptoPhone for
details. On most GSM networks, GSM to GSM secure calls can be made in either
V.110 or V.32 mode, however call setup in V.32 mode will take significantly longer
due to the way the call setup is handled in this mode.
Note that during a mobile to fixed-line connection from the CryptoPhone PSTN/1 to a
mobile GSM CryptoPhone, it is not possible to switch from clear mode to secure
mode or vice versa while in a call. This is due to the way the GSM network handles
outgoing voice and data calls.
H. Switching the CryptoPhone PSTN/1 off
The CryptoPhone PSTN/1 needs to be turned on all the time in order to be able to
accept incoming calls. It is designed to run for months and years without interruption.
In case that you need to, e.g., transport the unit to a different place, please press the
Power button on the front of the PSTN/1 encryption unit for five seconds. The blue
light will turn off. You can then disconnect all power and telephone lines attached to
the unit in reverse order as when you did when turning the unit on.
