Migration of VOIP/SIP enterprise solutions towards IMS
MetadataShow full item record
Voice-over-IP solutions based on SIP and Skype are now widely spread and accepted by end-users. "Traditional Circuit Switched" voice services suffer from declining revenues, high maintenance cost, and a lack of integration with Internet applications. For an enterprise customer it is increasingly difficult to make a decision about which VoIP solution to select. For fixed and mobile operators new solutions based on IMS are on the horizon, and investment strategies for VOIP solutions are difficult. The research project will investigate VoIP/SIP solutions based on open source as a starting point, and outline their possible migration towards IMS for enterprise customers. Major differences between current VoIP/SIP solutions and IMS will be outlined. Architecture components that allow interconnection, extension and migration of VoIP solutions towards IMS shall be proposed. Possibly “proof-of-concept” demonstrations will also be built to verify interoperability aspects. We have proposed four IMS migration solutions that connect a VoIP/SIP enterprise solution together with the upcoming IMS technology. We also outlined a possible migration roadmap that shows in what stage of IMS development the solutions can be implemented. Furthermore this thesis shows the design and implementation of a working state-of-the-art VoIP/SIP enterprise solution.
