In the future it is always helpful to provide the model type and which interface you are trying to use (pstn/fxo or pbx/fxs). From your posting I am guessing that you are using the PBX/FXS interface. The only thing you need to do is make sure that the unit is online and dial tone will be provided to the PBX/FXS ports.
If you are using the pstn port, then again, make sure you have configured the unit online and check that you have good dialtone on your lines by plugging a phone directly to the line.
