Configure Security Callback
The function “Security Callback” allows that a call at the INSYS GSM 4.3 initiates a
call to a pre-defined phone number. The function will trigger a callback after suc-
cessful authentication using a password. The password is absolutely necessary for
the security callback. The INSYS GSM 4.3 establishes a data connection after trig-
gering the security callback. Therefore, the security callback is only functional, if
your SIM card supports outgoing data connections. A security callback with a voice
connection is not possible.
Configuration with HSComm
In order to enable security callback, configure the authentication pass-
word on the “Access Control” on the “Password for” panel using the
“set password” button under “data connection, security callback”. Enter
the phone number to be called back into the entry field “Callback num-
ber”. You enter the phone number here, which is called by the INSYS
GSM 4.3 as a reply to an incoming call.
Enable the “automatic call acceptance” and enter the desired number of
ring tones until pick up as described in the respective section.
Configuration with AT commands
In order to enable the security callback
and configure the phone number to be
called back, use the command
AT**CALLBACK=<Number>
In order to disable the security callback,
use the command
AT**CALLBACK=
In order to query the configured security
callback number, use the command

In order to set the password, use the

with the password and
<rp>
with the repetition of the password.
AT**PASSD=<np>,<rp>
In order to change the password, use the
command
Replace
<p>
with the current password,
<np>
