What technology is available to help effectively manage IP telephony traffic?  PacketShaper from Avaya is an application traffic management appliance providing bandwidth management control, in addition to Layer 7 visibility, to optimize network QoS and application performance. PacketShaper's traffic shaping technology allows organizations to fix WAN and Internet performance problems, and actively prevent network congestion by controlling bandwidth utilization and application performance. PacketShaper allows organizations to maximize QoS for mission-critical applications -- from voice and video to CRM and ERP -- for over 400 applications.   PacketShaper helps ensures that Avaya IP telephony traffic, which is always susceptible to interference from competing traffic on the network, runs smoothly on a converged network with minimal packet loss, latency, or jitter. In particular, PacketShaper delivers Layer 7 quality of service (QoS) for Avaya IP telephony traffic and other mission-critical and latency-sensitive applications. It monitors and controls the performance of IP telephony and other critical traffic over the WAN and Internet, effectively managing all critical IP telephony protocols to deliver the highest quality end-to-end communication on an individual, per-call basis .
