Hi! My boss just gave me a new project :D, to create a database that calls a Client's phone number from a Form

. For example, the user will:
a. enter to a form call frmDialPhoneNumber
b. search for a Client
c. press a "Dial Client Phone Number"
d. talk with the client
e. Click Hang-Up to terminate call
Can I use only Access 2003 with VBA to create this database? or I will need to create a program in Visual Basic.NET or some other language that will be called from the form to do the job??? I try using the AutoDialing future from the Access Misc Controls, but that uses the Windows Phone Dialer program to do the job (to much for the user). Any ideas will be appreciate!
Thnks
