GV (obi100) outbound voice breaks up

[Naperville]

I had no problem in the first a couple of weeks of using obi100/GV. Since then voice quality has been poor most of the time. Inbound voice is ok in general.
I remember that I updated a firmware for this device and not sure if that affected the voice quality.
I have a Clear 4-G internet service provider, max download speed 6M/s and most of the time I am in the 5 M/s ranges.
Any advice / suggestion is appreciated!

Set your phone to full duplex and see if that helps.  You can only do that via the phone. 

See here: http://www.obitalk.com/forum/index.php?topic=3788.0

If you have a router the supports QOS, give your Obi priority over everything else.  That way of you are streaming or downloading something but then talk on the phone, you don't get choppiness.

What type of internet service do you have? DSL is often symmetrical up/down, but cable can have upload speed that is 10% of download, so OG voice would be affected.
Check with:

and post the results here.
Also, are you using a PC while talking?

I can't see the value of a speed test, and large pipes are not needed for voip.

What matters is the quality of the connection. 

@ Naperville

Give this test a shot, what you are looking for is low jitter and hopefully ZERO packet loss.

Mine

Test Type:   Voice over IP
Downstream Jitter:   3.65 ms
Downstream Loss:   0 %
Downstream Packet Order:   100 %
Upstream Jitter:   1.7 ms
Upstream Loss:   0 %
Upstream Packet Order:   100 %
Packet Discards:   0 %
MOS Score:   4.2

The best MOS of 5 would be perfect, ain't gonna happen.  Anything over 4 should provide good quality.

...a value of 4.0 to 4.5 is referred to as toll-quality and causes complete satisfaction. This is the normal value of PSTN and many VoIP services aim at it, often with success.

Try a test.

Sorry I couldn't login to this forrum for a while and had to sign in a new acct Naperv.

Here is the test report:


Upstream jitter                    11.8 ms
Downstream jitter              1.7 ms
Upstream packet loss              9.8 %
Downstream packet loss      0.2 %
Upstream packet order           100.0 %
Downstream packet order       99.8 %
Packet discards                       0.8 %
MOS                                       1.0
REGISTER ms                    746 ms
INVITE ms                            725 ms
BYE ms                            439 ms
Test   Voice-over-IP

My ISP is Clear 4G, download <= 6 mps, upload <= 1mps.
Looks pretty bad: MOS = 1.0 and jitters are high.

Also my speedtest results are:

ping=75 ms
download=8.81 mbps
upload=0.98 mbps

I hope this is not over kill.

Here are two pretty comprehensive VoIP 'quality tests':  

http://voipqualitytest.com/

http://www.phonepower.com/wiki/Speed_Test

The second one has a test (see Click Here to test) and also explains results when you scroll down.

Note that Java needs to be enabled in the browser to either test.

And, you want to connect the PC you use to run this test to your router the same way your Obi110 is connected, meaning via an Ethernet cable, a WiFi connection to your pc and a 10 Mb or 100 Mb wired connection to your Obi100 are not going to give useful results.

Will do that when find an ethernet cable. Thanks.
