It started couple of months ago with losing the other person for 30 seconds or so and then coming back. Now we lose the other person and might not get them back until we call again. Its a intermittent problem but happening quite often. Call quality is good when we have the other person.

Update on test results, these are only an hour and half later from the original results. I haven't been tracking these but maybe I need to.

What kind of internet service do you have? I've had a case where call quality would be terrible (with drops) once in a while and found the cable modem to be faulty. It was having intermittent problems. New modem fixed the problem.

I was disconnected using my office OOMA at least 3-4 times today. The caller I was speaking with suddenly started to fade in and out, and they could not hear my either.

The same issue happened today on our home OOMA (Core and scouts) at a totally different location here in Phoenix about 5 miles away with a different internet provider.

Lets face it - OOMA is suddenly becoming unreliable. What is happening over there guys? This has been a rock solid service, but recently the quality is terrible.

Ooma has been exceptional for me and all my friends/family up here in the great pacific northwest. Can it be that we are so close to where ooma is? :) Not sure why some of you are experiencing these quality drop offs (if they are indeed non internet service related); hope ooma will shed some light on this subject via this forum (ooma_status just reported an outgoing call issue today that was fixed but no details about what happend reported anywhere).

I have Comcast cable internet. I replaced my modem about 2-3 years ago because I was told from Comcast that it was probably bad. I have a Motorola Surfboard now and I have about a 5 year old Linksys WRT54g (I believe that is right). How can you test to see if the modem is bad? Could it be the router going out?

On speedtest.net I'm getting about 17.28 mb/s download and .34 mb/s upload speed. I understand these numbers change all the time being its cable internet but I use to get about 3.0 mb/s upload speed most of the time. Now last night at about 9:00 PM and today at7:30 AM I'm getting this .34 mb/s upload speed.

If you have cable modem, check into doing these things: viewtopic.php?f=2&t=9142#p63650

I have to agree. Ooma has been horrific for me over the past month or two. Constant echoes and the other person dropping off. Also the person will call and I can't hear them but they can hear me. Now what happens is when I hang up the person on the other end hears that last second or two of audio that they said. Very strange behavior to say the least. I have FIOS with rock solid ping times, little latency and high bandwidth (30/25). Given the fact that nothing has changed for me in the past year and I went from rock solid Ooma service to this Russia roulette phone service, it is frustrating. I can deal with CIDCW not working on my phone but this call quality issue is too much. Over 50% of my phone calls now are having issues. My wife has given me the ultimatum that if this does not clear up we move off the service. Sucks I guess but she is right. The past two months have been too much to deal with.
