Sending a fax message to GSM and modem connection through GSM (UMTS, LTE)
When connected device is able to send CNG tone (1100 Hz for fax 1300 Hz for modem), the
gateway recognizes whether the call is fax or data, the connection will be established
automatically. When the tone is not send or some problems with recognition occurred, is
necessary to dial before destination number code *01* for fax call or *02* for data call. This code
us used to inform the Gateway, that the call is a fax or data call.
Receiving a fax message from GSM
It is recommended to activate separate fax number on your SIM card – multinumbering
scheme. Fax messages must be routed to fax number, data call to data number. Incoming fax,
data and voice calls will be than automatically recognized. It is possible to set ring pattern for
fax and data call, different from the pattern for voice call.
If the fax or data number is not activated, the call from analogue network routed to your GSM
number is not detected as fax or data call and is routed via the analogue channel of GSM
network and the connection is not successful. In this case it is possible to set the gateway using
DTMF commands using device connected to FXS line. These commands can be used for data and
fax routing to FXS line or serial line.
