Symptoms
A Common Programming Interface for Communications (CPI-C) application that worked in a Microsoft SNA Server 4.0 environment may not work in a Microsoft Host Integration Server 2006 environment. This problem may occur when the application uses another programming interface such as the Request Unit Interface (RUI) or the Session Level Interface (SLI) in addition to the CPI-C interface. In this scenario, a message that is intended for the CPI-C interface may be discarded by the RUI or SLI interface. You may notice that the Accept_Conversation call in the CMACCP function never finishes, even if the call is allocated.
