Windows 2003 - Acceleport RAS 8 modem issues

Hi I have a Acceleport RAS 8 Installed in a windows 2003 server machine.

The problem i have is when i use windows Network Connections and try and dial the internet i get an

error 676: the phone line is busy.

When i dial my own phone number the machine dials out but there does not appear to be any handshaking trying to happen the line has no sound.

Any ideas would be great
