Why is the voice quality for calls so bad?

I like Ring Central...but the call quality is super bad. Very frequently it is so bad that people cannot understand what I am saying as it cuts in and out and sounds "robotic". We've checked and it is definitely not our internet connection and it happens in all of our multiple offices with multiple users and their phones. This is a critical issue and should be fixed yesterday. This problem could force us to leave Ring Central for a different provider.

This reply was created from a merged topic originally titled Cannot get clear calls (QoS). Hello,

I have been running a small office now for about two years and to this day I continue my battle with getting clear VoIP calls. I have literally tried close to 10 different routers to date and RingCentral is now my 4th Company and I am unable to get clear phone calls. 

The biggest problem is that they become choppy when someone on the network is watching a youtube video or downloading a large file. I cannot get QoS to kick in to create a quality phone call. 

I just took out an EA4500 today where I followed the instructions exactly as RC has it plus enabled all of the port triggering. The problem is our bandwidth spikes (we have a 10/10 symmetrical line) when large files are downloaded. When I load a large youtube video (say 50 minutes long), the light gray bar will go across the screen indicating the video is loading and buffering. All during this time, I will experience poor audio quality. I constantly ping google.com and you will see the ping times jump above 100+ ms sometimes 300+ms briefly until the file or video is loaded. All during this time, call quality goes to crap.

Currently I am on an Adtran 3120 which is supposed to be enterprise and designed for VoIP use. Can anyone help me please?
