According to a new report by Juniper Research, the market for VoIP business services is set to reach $18 billion by 2010. In a separate report by Integrated Research, based on a survey of 1,232 executives worldwide, 78 percent of large companies say they are deploying IP telephony, largely to enhance communications with IP applications and services such as video conferencing. With business critical applications like voice and video now running on IP networks, guaranteeing uptime, performance and service levels is vital.

While the excitement and promise of VoIP is real, organizations have been cautious in their deployments due to a lack of end-to-end visibility into network performance, and the inability to manage the call quality and reliability that users have come to expect from traditional public switched telephone networks (PSTN).
