IP Multimedia Subsystem (IMS) is a standard that is use in products, vendor system platforms or interoperability programs. IMS is an integral piece of the big vision of telecommunications and is very complicated and abstract.

IMS started as a technology for 3G mobile networks (under the auspices of the 3rd Generation Partnership Project (3GPP) and is a key to fixed/mobile convergence. It builds on the Session Initiation Protocol (SIP), which has emerged as the crucial technology for controlling communications in IP-based networks. IMS is about services and applications, enabling telcos, mobile operators, and other service providers to offer rich multimedia services across packet-switched and circuit-switched networks. It is standards-based and uses open interfaces and functional components that can be assembled flexibly into hardware and software systems to support real-time interactive services and applications.

IMS will help provide a seamless, consistent experience across multiple access technologies, devices and locations, whether wireline or wireless, narrowband, wideband or broadband, business or personal. The implementation of IMS signals a fundamental shift in the way telecom services are created and delivered, helping bring about true fixed-mobile convergence for the multimedia applications. damaka's products are IMS aware and compliant with the industry standards.
