SYMPTOMS
========

Tcmapp.exe does not properly handle situations in which a TAPI service provider
(TSP) removes line devices. For example, a phone is removed, the old line device
is removed, and a new one is added. In this case, Tcmapp.exe stops enumerating
devices, so all devices after added after this device are ignored.
