Awful Call Quality

Post by atlgeo » Wed Jul 15, 2009 12:05 pm

Help!

The calls echo a lot, I also hear many other conversations (worse when talking to cell phones), it breaks up this is awful!!!

Several Speed Tests ave is listed below:

Jitter (both ways) 18 ms
Packets Lost 0%
Download Speed 108529 bps
Upload Speed 108824 bps
Download Quality 14%
Upload Quality 99%
Max TCP delay 2292 ms
Roundtrip time 198 ms
Bandwidth 112000 bps

If the call quality doesn't get better, then its going in the trash can!
AT&T says the line speed and packets are good, they didn't know what Jitter was. I've tried changing the QoS setting, but no diffierence. The
set up makes no difference phone-modem-ooma-router-computer or phone-modem-router-ooma same test results.

Same test results without ooma connected. Whats going on!!!!

Download quality 14%

I would not expect it to work at all with that low of a download quality.
This isn't an ooma problem, it's an ISP and / or home networking problem.

Indeed it is. Check your home networking first, if that doesn't help, have an AT&T technician come out and check your line (You said AT&T right?)

Ours was bad until we got our line fixed.

Also try testyourvoip.com as I've had really low Qos scores (as rated by the Voip test site) and my quality is fine. If your speed varies much you'll get terrible Qos scores. Jitter on the other hand could be a problem here and is the problem of your ISP.

Adjusting Qos on your system will only prioritize traffic on your LAN. Therefore if there is no LAN activity and you still are having voice issues than it is likely the ISP and no amount of Qos tweaking will help!

Maybe it is just me but I can't read your PDF file... Everything is all jumbled up.

This isn't an ooma problem, it's an ISP and / or home networking problem.
Also for this reason - Max TCP delay 2292 ms !
TCP delay needs to be less than 100ms for VOIP to work reliably!

I agree this is a netork / ISP issue
