See my thread.

I just tested with https://www.whichvoip.com/voip/speed_test/ppspeed.html

and I got 6 green circles (no issues). My incoming and outgoing calls gets a scrambled sound. I have used Ooma for over 5 years and never had this issue before. Is there anything I can change to test?

@Murphy, Thank you for the link. I ran the test and got 6 green circles, so apparently I don't have a problem with my internet connection. I'll just need to keep looking for answers... wondering if the "east coast server" has anything to do with it??

I am on the east coast server. I don't know where it is located but I am in south east PA.

Can I be moved to the East Coast Server. Tons of static and dropped calls.

done

My call quality has been horrible the past few weeks. Calls cutting out, dropping at times, and just generally can't have a conversation. I have amazing internet. I work from home and have to have a reliable internet source.

I too have been having constant call quality issues for the last several months and even replaced my Ooma Telos to make sure it was not the Telos. I ran a speed test during a call and you will notice the difference when I was on the call and when I was not on a call.

I also ran the jitter test mentioned earlier in this thread and everything was green.

Jitter .9 ms
Packet Loss .2
MOS Score 4

When I contacted Ooma this was the response I received:

Your are experiencing issues with call quality because of 2 possible reasons:
After a couple of tests from our end, we found that your upstream bandwidth is not stable, thus:

Based on speed test result the suggested value for upstream bandwidth is 1080.0 kbps
Based on speed test result the suggested value for upstream bandwidth is 900.0 kbps
Based on speed test result the suggested value for upstream bandwidth is 640.0 kbps
Based on speed test result the suggested value for upstream bandwidth is 790.0 kbps

Your Ooma device is already connected directly to the modem so it should already be prioritized on your network, so there is not much we can change on your setup; unless the device itself/hardware is deteriorating. If it is, then we suggest for you to try and replace your Telo.

As I mentioned I swapped the Telos with no improvement and am not sure where to go from here I have XFINITY and use an Arias CM820A modem and any constructive suggestions would be appreciated.

Thanks.

Run this test.

I found that my modem had a problem and was losing up to 17 % of my upstream packets. My outbound audio was unintelligible. A new modem solved the problem.

Using fast cable for Ooma for about 6 years, calls started dropping or being randomly going to VM without ringing a couple days ago (using hardwire handset), can you please work your magic? Thanks.
