Do a Start | Run dialer.exe
From Edit | Options
Check the 'Preferred Line for Calling' and set to 'Phone'.

Just a SWAG...

>During this time it has always worked fine and still does on most of my installations. However, the aquisition of a new Gateway running XP Pro has things messed up. The installation and config of the TAPI drivers is the same as on the other machines, but for some reason when the command calls the windows dialer, the dialer thinks it is making an internet call rather than a call through the phone switch. This results in a "Server is not responding" error.
