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.

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.

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.
