Abstract: In future telecommunications systems, behaviour will be
defined by inexperienced users for many different purposes, often
by specifying requirements in the form of policies. The Call Pro-
cessing Language (CPL) was developed by the IETF in order to
make it possible to define telephony policies in an Internet tele-
phony environment. However, user-defined policies can hide incon-
sistencies or feature interactions. In this paper, a method and a tool
are proposed to flag inconsistencies in a set of policies and to assist
the user in correcting them. These policies can be defined by the
user in a user-friendly language or derived automatically from a
CPL script. The approach builds on a pre-existing logic program-
ming tool that is able to identify inconsistencies in feature defini-
tions. Our new tool is capable of explaining in user-oriented termi-
nology the inconsistencies flagged, to suggest possible solutions, and
to implement the chosen solution. It is sensitive to the types of fea-
tures and interactions that will be created by naive users. This tool
