Abstract

Voice-over-IP (VoIP) solutions are now widely spread and accepted by end-users. For an enterprise customer it is increasingly difficult to choose one of the numerous VoIP solutions which are available today. What options exist for an enterprise VOIP/session initiation protocol (SIP) solution to migrate from today\´s solutions towards interoperability with future IP Multimedia Subsystem (IMS) solutions, and what would motivate such an upgrade? We visualize four such solutions and position them along a possible migration roadmap. A common VoIP/SIP/IMS research platform is necessary as a test-bed for establishing an environment for development of future "All IP" products and services.
