Basic settings
Settings of basic parameters of GSM.
Number of digits dialed from ISDN – sets outgoing ISDN dialings into GSM
networks.
− Maximum – the maximum number of digits to be dialed into a GSM network. Any
dialing longer than or equal to this parameter is dialed automatically (without
waiting time).
− Minimum – the minimum number of digits to be dialed into the GSM network.
− Waiting for next digit – time (in seconds) for the PRIGW to wait for the next
dialed digit. After this timeout, the number is dialed automatically into the GSM
network.
Voice parameters of GSM/3G modules – sets parameters of GSM modules.
− Receive/Transmit level – selects the receive/transmit volume. Caution! We
recommend you to keep the default value to avoid negative effects upon other
transmission parameters, such as echo. Do not change these settings unless
absolutely necessary.
Call delay - the minimum timeout between the end of a call and the beginning of
another outgoing call for one GSM module (Incoming and outgoing calls are not
rejected during this timeout). The optimum time is 2 seconds. Unless absolutely
necessary, do not change the default value to avoid system instability.
DTMF number – sensitivity of DTMF receiver from GSM network. Parameter “delay”
means 10*miliseconds which is added to default value 20ms. The total time is
