How to interpret these voice call statistics?

[Quattro Pete]

I've got a VOIP home phone from AT&T Uverse.

When I log into the gateway, I can see various call stats as below, but I'm not sure how to exactly interpret it. Is it overall good/bad? I just understand there was no packet loss, which I take is good, but what about the rest?

BTW, this is mostly just for my education. I don't think I'm actually having any issues with voice quality.

Thanks!

Except for the packet loss stats (transmission failure), it's all time statistics. Jitter and delay.

Nothing stands out as being a problem.

If you run a robust speedtest during a call, you will probably see some of the numbers spike. Possibly during some Netflix or YouTube usage, too. If your phone is independent of your internet, then the phone won't be affected by internet usage.

It's the same AT&T gateway managing voice and internet for me, and technically it should give voice traffic absolute priority, thus not allowing it to be affected by internet traffic. Alas, that's just theory. I will try to max out my internet connection to see what effect, if any, it has on voice. Thanks!

I doubt it will have any effect. There is much more bandwidth available on the line than what your internet modem is probably provisioned for.

The only thing I can think that may cause degradation would be since it's a shared device, if the internet side uses enough resources (CPU, etc) to slow down the processing of the voice side. That's pretty much it, barring some sort of issue upstream.

Should be a solid service for you.

I should have clarified, I have the ATT gateway set up so that it just passes all internet traffic to my router. Another words, the gateway is not doing any firewalling or NAT, so hopefully it is not being asked to work too hard.

The only thing that does not get passed to the router is the voice traffic. I have the phone connected directly to the ATT gateway.

Do you have TV too? If so, fire up as many HD streams as your gateway supports, start some Netflix or download some ISO images, etc and then make a call.

My 3801HGV gateway sometimes gets overwhelmed and reboots.

I think I'm paying for 18mb internet, one phone line and HDTV.

I have FTTP, and if I go to a faster speed, they'll probably need to replace the ONT connected to my home as I'm at the max speed it supports. They do offer 24mb, but according to the last tech who was here, my ONT doesn't support it.

I just wish Google fiber would get close so AT&T would offer Gigapower in my neighborhood.
