At Communications Solutions[TM] Expo Fall 2000, Telephony@ Work launched a new Multimedia Overlay Network as part of its CallCenter@nywhere e-contact center solution. It is a means of unifying geographically distributed call centers (including those using legacy telephone systems) into one seamlessly integrated virtual contact center so that ACD transactions on all media can be routed to the best-skilled agent, regardless of agent location. The solution is intended to replace telephone-only switching schemes based on Signaling System 7, which do not address load balancing of any media other than circuit-switched voice telephone calls. Users of the Network can deploy Call Center@nywhere to unify formerly separate, noncommunicating PBX or ACD systems into a single system view or virtual call center.
