Anyone knows if there are some good tutorial or example about tapi programming of avaya? i downloaded the code example from avaya, and worked out most of the functionalities. the problem is the example that avaya provides is not as complete as phone manager, e.g. parking slots ( i managed to un/park calls, but i suppose, when a call is parked, it should be visible to any internal users, which mean tapi will execute call back functions for everyone) and the forwarding function does not work either in example, don't know why. anyone got experience on this?
