In an ever changing and fast moving global environment, integrated systems that boast a wide array of applications are best suited to meet the exact demands of customers. Unified and comprehensive systems are the order of the day and every aspect of business from communication to management is based on such models. In earlier days, PABX (Private automated branch exchange) systems were used in businesses for call handling and routing and they served as the main communication systems along with other independent systems. With the growth in technology, the need to have unified communication solutions grew and they are a reality today. Unified Communication Systems help in seamless communication across integrated devices that include instant messaging, IP telephony, data sharing, web casts, conferencing capabilities and speech recognition. The system needn’t be a single component; it is mostly an integration of a variety of top notch and latest systems that enable seamless communication.
