When I make outgoing call thru the GW, the call is rejected by the gateway.
What may cause it?
 The communication protocol on the line from your PbX to the gateway is
set to Euro ISDN DSS1 according to Q.931
 The SIM cards are logged to the network correctly – both LEDs called
GSM1 and GSM2 must be off (they are blinking during logging process,
but they go off after they are logged successfully)
 You see good signal strength in the Diagnostics (between -60dB and -80
dB)
 The SIM cards are active, they have credit, they are not blocked by the
GSM operator
 If you are using CLIR function Enabled in the gateway, check if this
feature is enabled in the SIM card by the GSM operator
 The dialed number is in correct format, it matches one of the Network
Lists and this Network List is Actively used in the LCR section
 If you have set Max. number of called minutes, make sure those minutes
have not been already used up.
 The Time limitation of SIM card (which part of the day it shall be used) is
set correctly
 Time and Date is set correctly in the Gateway
