I would like to control the out going calls, whether they are local or long distance, however what Im noticing is that whether the computer is on or off, or the modem is disabled or enabled the call still goes through ??? &nbsp;I would like to start by writing an .NET application that detects when one of the phones are off the hook and what numbers are being dialed... any ideas on where I can start with this ?
