IBM Lotus Sametime Unified Telephony:
IBM® Sametime® Unified Telephony integrates telecommunications into your existing unified communications (UC) environment, so people can easily use more cost-effective telephony features. It provides one-number access to any device through rules-based intelligence, in-call management features and a softphone that allows users to place and receive calls from virtually anywhere. It masks the complexity of back-end integration with a middleware layer that provides connectivity to multiple telephone systems—both IP private branch exchange (PBX) and legacy time-division multiplexing (TDM) systems—allowing you to take advantage of your existing infrastructure.
