Abstract. Features provide extensions to a basic service, but in new
systems users require much greater flexibility oriented towards their needs.
Traditional features do
not easily allow for this. We propose policies as the features of the future.
Policies can be defined by the end-user, and allow for the use of rich context
information when controlling calls. This paper introduces an architecture
for policy definition and call control by policies.We discuss the operation
of systems based on such an architecture. An important aspect of the architecture
is integral feature interaction handling.
