Voice dialer support
One main characteristic of voice dialers is that they used to start playing the message if
they detect no ringtone on the line in a certain time.
By enabling this function, the module generates a simulated tone signal until the call is
received. This way can be avoided that the voice dialer starts to play the message before
receiving the call. By default, this function is disabled. To enable/disable voice dialer
support, connect a wired phone device to the module’s “TIP-RING” terminals, then pick
up the receiver and dial the following:
to enable voice dialer support:
0000
1
#
to disable voice dialer support:
0000
0
#
After entering the activation or deactivation command, the module confirms the execution
by emitting a beep through the phone.
Configuring by SMS commands
It is possible to configure the module by sending the appropriate command in SMS to the
module’s phone number from the phone number configured as SUPERUSER. After
receiving a command, the module sends response SMS, except for SUPERUSER
registration. The SMS commands are the following:
SUPERUSER#
The module sets the sender’s phone number as Superuser.
The
module accepts this parameter only if no Superuser has
been set before!
No response SMS is sent for this command!
SU=#
Deletes the current Superuser. The module accepts this
command only from previously set Superuser phone number.

firmware upgrade or in-call volume adjusting.
