Communication Manager is a reliable, resilient, SIP-based IP telephony platform designed for larger and fast-growing enterprises, and is particularly suited to intensive-operation installations such as call centres. Communication Manager scales impressively from less than 100 users to as many as 360,000 users on a single system and to more than one million users on a single network.

Recent evolutions further improve system connectivity and openness, which translates into reduced costs for trunking and connecting systems, faster deployment of new capabilities and increased options for linking communications and business systems. Communication Manager features strong interoperability with third party software and hardware thanks to its open standards support. This simplifies application integration and reduces total cost of ownership.
