Is the system working correctly?
If the MAIN PCB which has 4 LED RED lights, the top MSP light is flashing the 3rd DOWN PWR is Fully on and the 4 th DSP is Flashing?
We have 2 ISDN lines into our box and both have green lights but our handsets will not pick up any outgoing lines, the internal calls are working fine and the handsets dispay is correct. But now out going line just a Bleep Bleep 5 thime and then disconnect.
Is it our BOX or BT main lines into our BOX?
