Vista - Help Needed!!! CallClerk - PCI Conexant Soft Modem Voice/Fax

Im using a program called CallClerk to recieve Calls on my Second Phone Line. In XP Home SP3 it works fine with my Modem running in TAPI mode. When i use it in Vista Ultimate SP1 it fails to work corerctly. It will Alert me to incoming calls but thats it. It will not answer nor will it activate the Answering machine. I did some reading online about a problem close to this and it said i wouldnt have this problem If i had upgraded from XP instead of having a clean install because some files are not copied. I tried copying the files but had no Luck. If you all can give me any help at all that would be great!! Thanks Alot in Advance!
