QoS issues such as choppy audio, echo, one way audio and the like are network performance related. Basically, somewhere in the network path there is either latency, jitter, or packet loss or a combination of 2 or all 3. There is a free 30 day trial tool called "Ping Plotter" which can be run from the same network subnet that the phones are in which will measure the performance of the network path. It provides measurements of packet loss and latency at all hops in the path from the users location to the RingCentral servers. Here are the instructions for downloading and running this free tool:
Download and run ping plotter from your PC to our servers. This is a free download program that measures performance over an extended period of time. Here is the URL of where to ge tit: http://www.pingplotter.com/download.html
