My Voice Drops Out On Other End

Post by chiplatham » Fri Jun 12, 2009 6:35 am

hello...i am a new ooma customer and tried searching, but got lost in a bunch of threads dealing with other issues.

when i am talking to someone, the person tells me my voice drops out...ie silent for a moment...like i am getting another call coming in...like from call waiting.

my hub is connected to the modem via the modem connection on the back on the hub and to the router via the home connection, as per the instructions.

speed test per http://www.whichvoip.com/voip/speed_test/ppspeed.html

jitter 0.6 ms
packet loss 0.0%
mos 4.1
download speed 2.82 mbps
upload speed 487 kpbs
qos 95%

any suggestion how i can get this corrected? it is happening every 15 seconds or so according to the person on the other end. thanks.

You are leaving out some of the test results:

jitter should be to and from you to the server
TCP delays to / from you
Round trip times to / from you
QOS Upload / Download

If your voice is cutting out it may be that you you have high TCP delays or poor QOS in the upload direction

Rerun the tests and print all the results

Yes, now we can see your upload QOS is 83% which is probably why your voice is cutting out

You may have to impliment QOS on your OOMA hub if you have not already done so.

QOS settings depend on how it is wired into you network
(Modem -->Hub-->Router or Mode-->Router-->Hub)

I have a very fast FIOS connection so I never had to set up anything with QOS. I am sure others here that will read your post can advise you on making these settings

IMPROVING UPSTREAM QOS?

Post by chiplatham » Fri Jun 12, 2009 11:50 am

My ooma is set up Modem --> Hub--> Router . i know how to adjust the qos setting...what should i adjust it to based on my test?

right now it is set to about 20% of my average upstream numbers.

It should be at 80% of your upstream number. You could also try 100% and also try QOS upload set to 0. I've tried all three and haven't seen any significant difference myself. But setting it to 20% could be causing your problem.

sorry...i meant 20% less than total upstream....ie 80% of the total. i guess i will try 100% and see if that helps.
