This monograph presents different experiences related to architectures and mechanisms for deployment of telephony services, understood as especial features complementing the basic voice service. The context for these experiences is the transition of telecommunication (telephony) networks from circuit switched based systems towards packet based ones. The text of this monograph proceeds, unaltered for the most, from the author s PhD thesis Framework for Deployment of Advanced Telecommunication Services in Current and Future Converged Networks , carried out at the Technical University of Denmark in the period [April 2002, April 2005]. Even though the technologies presented in the text have evolved from that period until now, the presented scenarios and setups are still valid as interesting initial steps in the realm.
