The Teleboss 500/1000/2000 and Miricall PABXs have 2 comports available. The one
is used for programming and the other just for sending data.
Some management systems can get data through the Programming port.
By just changing the cable from the one port to the data port, you should be able to resolve this
problem.
If the problem persists after this, try having a look at our default fault finding
routines.
