In order to ensure the best possible experience with softphone clients for audio and video calling, Evolve IP has identified several recommended designs for both local installations and virtual.  Each design has independent Quality of Service (QoS) recommendations that ensure soft client traffic is properly tagged and prioritized from the end user machine, across the LAN, and optimally across the WAN to the Evolve IP data center depending on WAN access.

This document provides the best practices when deploying softphones that customers should follow to optimize call quality.
