Hi, We are currently experimenting with the AstTAPI driver for desktop integration. For outgoing calls, it seems to work exactly as expected. For incoming call alerting on the other hand, I am struggling a bit. I am using IdentaPop Pro as suggested in the Wiki, and if I enable debug, I can see "TAPI OnCallerID" events arriving okay, but nothing pops-up. I BELIEVE that what is happening is that the callerID is send correctly at first, but when the next TAPI "Ringing" indicator is sent, the callerID is empty in the TAPI data, which suppresses the popup. Can anyone shed any light on this if they have it working? Many thanks, Steve Davies
