Any response?
We have an issue with Tapi and 18.8, too. 3cx Tapi driver is active in windows client but does not act e.g. when trying to call out of Outlook contacts.

Would like to know too. TAPI on a Terminal Server seems to be a non-working option whatsoever. Which is very unfortunate.

We had the same issue. When the 3CX App does not have valid audio devices, the call will be cancelt immediately. Did you run it in CTI mode for a hardphone also?
