Hi,
IMO, you are best off using a commercial add-on. The ones that I know of a
COM (ActiveX controls), but will work in .NET. For example, amTAPI
(
www.allen-martin-inc.com) and TeleTools (
www.exceletel.com). There are
others for Dialogic boards, etc., so depending on what you want to do, and
what hardware you are using, you may want to investigate more. The few
hundred $ that these cost will be paid back in time saved on just the first
day (again, IMO).
