The issue is dropped calls on VoiP phones. 3 weeks ago we discovered a faulty modem. ISP replaced it and the issues continued, static in calls, dropped calls, no dial ability etc. We have run a voice scout test from Intermedia and it showed all kinds of packet loss. Next we ran packet tests. Again, dropped packets Now I have the MX68w in place, pulling over 550mbps at the gateway, 400mbps on my laptop and still unable to stay on the phone for more than 20 seconds before call drops. I just got off the phone with the ISP (spectrum) and they verified that the modem has been 100% fully operational for the last 11 days, ping tests are good and no packet loss showing on their end. I connected a phone directly to the MX bypassing all switches ran a continuous ping test to the ip and tried to make a call and when I am able to get dialed out, which is seldom, the call drops in 20 seconds but the ping test never waivers. I’m stumped!
