    David,
    do you get this CME_STREAM_INACTIVE only on the that single machine with the
    CS_DISCONNECT issue or on all of your installations?

    Did you encounter any side effects when "disconnect the call while the server
    handling CME_STREAM_INACTIVE event?"

    In case you didn't already took a look at the TAPI3 samples from P-SDK
    regarding CME_STREAM_INACTIVE, these files have a reference to it:
    \Core-SDK\Samples\NetDS\Tapi\Tapi3\VB\dtmf\DTMF.Frm
    \Core-SDK\Samples\NetDS\Tapi\Tapi3\Cpp\tapirecv\Processing.cpp
