Meshing up telecommunication and IT resources seems to be the real challenge for supporting the evolution towards the next generation of Web Services.

In this paper we describe StarSLEE platform which extends JAIN-SLEE in order to compose JAIN-SLEE services with Web services and the StarSCE service creation environment which allows exporting value added services as communication web services, and we analyze open issues that must be addressed to introduce Web Services in new telecom service platforms
