  IP multimedia subsystem is used in every IT sector across the world, including regions such as Germany, Mexico, and Japan. The IP multimedia subsystem is a unified architectural framework for delivering IP audio-video applications over a circuit-switch-like network. Traditionally, handheld digital telephone services over an IP network have offered voice call handling over a packet-switch-style network, and not over an IP packet-switched network. Packet switching and the IP multimedia layer provide distinct advantages over traditional circuit-switch technology. With the advent of the IP multimedia subsystem, more services can be delivered over IP networks at greater speeds and for less cost. There are two primary benefits to using IP multimedia subsystem over traditional circuit-switch networks: better-integrated media access and greater portability. In regions such as Germany, the prevalence of IT companies has increased the requirement for IP multimedia subsystem. For instance, acco
