Doing this all outcoming calls starting with
0870
will be stopped (will not be carried out).
4.9.1.2. Whitelist management
All outcoming calls identified with the asterisk symbol ( * ) can be directed to that same number with the
equal sign ( = ) as destination. With the same format used in diverted calls, a whitelist can be created
with the following SMS:
12345,S:$tro6:”
*
“,S:$trd6:”=”
Response:
[“OK”,“OK”]
This is the standard behaviour of the device when the whitelist is empty.
4.9.1.3. Polarity inversion simulation
The device has the capacity to simulate polarity inversion in outcoming calls (polarity is not inverted as
standard). To do so it counts with the parametre
$swpl
and it can be set to the values
t
or
f
(no
quotation marks) as shown:
12345,S:$swpl:t
– inverts polarity
12345,S:$swpl:f
– does not invert polarity
In both cases the response is:
[“OK”]
