Obi and GV calls blank out after a while
jjk99:
I'm not sure how to describe this but my Obi 202 has updated firmware, is connected to google voice and works to make and receive calls. However, sometime during most calls, it seems to blank out and the other party cannot hear me, nor can I hear them. If I connect to my OOMA, no such issues. What is recommended for troubleshooting this? thank you

I have the same problem with my 1032 from time to time.

I am also having this exact same problem. I also have an OBI202 with updated firmware. I am using the USB Wifi adapter for the internet connection. But, it's within 15 feet of the Wifi router.
I am also looking for troubleshooting ideas. I have seen the troubleshooting talking about intermittent choppiness. But, that isn't what is happening here. The "blank" time is somewhere between 5 and 15 seconds and happened multiple times. There have been other instances where calls have been fine without the "blanking" effect.
I don't believe this is a packet priority issue. If packet priority was a problem, it wouldn't last for 10+ seconds. And, my house has many phones and/or computers that don't have problems with the internet connections.
I am going to start a ping test saved to a file on another computer to make sure the internet truly isn't the problem. The next time it occurs, I can look at the ping output and verify if the internet connection was interrupted.
I'm also going to see if there are any logs on the OBI202 that might give me any clues.
Thanks in advance for any help anyone can provide. I'll be happy to try suggestions.

Looking at statistics, I see the following on the OBI202:
Under Status->SP Services Statistics
RTP Statistics
Parameter Name SP1 Service Status
PacketsLost 2455
Don't know if this could have anything to do with the "blanking". I've reset the statistics to see if this is normal. I also see smaller numbers in the "overrun" and "underrun" stats. But, those numbers seem to be too low to be related. Looking online I see mentions of 50 packets per second for some RTP sessions. I'm not sure what the OBI202 uses.
My wife estimates that she had four instances across two calls this morning that were the following durations in seconds: 7 15 12 6
That's approximately 40 seconds which would be approximately 2000 lost packets at 50 packets per second. That's not a long way off from the 2455 above.
If that is the root cause, the question would be is that an OBI202 problem or a Google Voice problem? Or, could it be either? And, how would one troubleshoot to be able to know?
I was recently using a GVMate and never ran into this over maybe a year. So, my gut says it's the OBI202. Just how to prove it and is there a way to "fix" it?

If you are experiencing intermittent call quality issues, I'd suggest testing the quality of your home internet connection. Note that traditional speed tests, such as speedtest.net, are useless for this purpose, since VoIP call quality is influenced by jitter and brief dropouts, which wouldn't be a problem for web surfing or file streaming with buffering.
Try the VoIP G.711 codec test on this website, which simulates an actual VoIP "conversation":

Run several tests, using different far-end destination servers. If your MOS is below 4.0, then you've got a problem with your internet service.
