If you connect an alarm control panel to the simulated line, no matter which operating mode you
choose, the device will process alarm system messages received or passed through by call.
Thereby, it is possible to send further notifications (voice call, SMS, Push, e-mail) about these
messages, according to the alarm system event settings. The difference between the operating
modes is just that the device will or will not pass through the call to the GSM network, depending
on the number dialed by the alarm control panel.
Configure the connected alarm control panel to wait for the dial tone before dialing!
Attention! Please note that in certain cases you may experience issues with reporting to CMS
over DTMF-based voice call. Success of communication highly depends on the properties of the
given GSM network, such as line quality, line noise and DTMF handling. Due to network
digitalization, DTMF signal tones might get distorted while being processed by the network in such
extent that the receiver will not be able to interpret the transmitted Contact ID event codes. The
risk of this is even higher if the signal is transmitted through multiple GSM operators (e.g., if using
SIM cards from different operators on the transmission and reception site). The device offers an
option to adjust the signals to correct such problems, therefore, if necessary, special DTMF
communication parameters can be configured in the “Advanced settings” menu.
Auto dialing – emergency call function:
Automatically dialed phone number: this function can be used for some special applications
(e.g., automatic emergency call). If configured so, the device will dial the given number
automatically through the GSM network after the delay configure in the “Dialing delay” section,
upon picking up the receiver of the landline phone device connected to the Adapter2. When the
automatic dialing function is used, the device can also be used with an alarm control panel, if an
appropriate dialing delay is configured.
Due to security reasons, the auto dialing feature is not available if “Receive and process alarm
system messages upon any number dialed” option is selected under “Operating mode”.
Dialing delay: the device will dial the phone number configured in the “Automatically dialed
phone number” section after the delay configured here, when it detects off-hook on the simulated
line output. If you wish to use the auto dialing function when the device is being used with an alarm
control panel, configure the dialing delay so that the alarm control panel should have enough time
to start dialing the number it has to call, still before the device starts dialing the number to be called
automatically. The device will not make a call to the number to be dialed automatically if it detects
dialing on the simulated line during the configured dialing delay. In this case it will manage the
communication received through the simulated line.
Miscellaneous settings:
Incoming call from unknown phone number: in this section you can configure what the device
should do when it receives a call from a phone number which is not configured in the device as a
user phone number, or a call from private number (with hidden caller ID).
Available options:
• Forward calls to the simulated line: the device will forward these calls to the simulated
phone line output (LINE). If a landline phone device is connected to the line output, the phone
will ring, and speech communication is possible after accepting the call. Regardless of this
setting, when a call is received from an unknown phone number, a related service event is
generated for which you can configure output control or notification sending.
• Reject calls: the device will reject calls received from the given phone number.
