Check the SIM card.

Select a place with a good GSM signal.
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
Call is not disconnected immediately
