Thanks for y'r reply. I think what you say is the only way indeed, though I am still investigating if some kind of Window hooking would work.
Personally I really don't understand why this functionality is missing. ET is in every aspect superior when combined with VRS, Remote Monitor etc. But for my clients (callcenters) it is absolutely necessary to call with "progressive dialing" (for example: automatically calling the next number when "line busy" is detected).
Another disappointment: I asked NCH about this, but I get no answers at all.... not even a "no we're sorry"....
