The TurboPower's award-winning Asyn Professional is now available freeware with source code.

Personally I don't suggest Async Professional for phone automation. When Async Professional was not freeware, my employer company bought it and we couldn't use it for our telephony application.

Async Professional is good (because of no other alternative) for writing fax receiver/transmitter programs, but for telephony applications (specially for interactive voice) it sucks.

The other alternative for Telephony is ExceleTel TeleTools, which is much better than Async Professional. Unfortunately this one is not freeware.
