I built a small Cisco IP Phone Service in .NET that simply pulls contacts out of an API for a sales program we use and lets you search and display contacts, and then call them from the Service. I want to extend it so that I can save the info for each of those calls. For example, the call-time, who was called, at what time/date, etc. I assume that I have to use some kind of CTI/TAPI thing, but I know nothing about that at all. Can someone point out a resource to look at so I can maybe get this working? Thanks.
