One more thing, how do i explain it to the ISP about that jitter? There was a time I called and the support had no idea about that jitter and finally he transferred me to his supervisor and saying that the jitter has nothing to do with the voice quality and they have nothing to do with that choppy sound. And she told me to call ooma instead.
Please do not make multiple posts of the same issue!

Friends don't remember what Landline Integration was or why we did it.

No offense taken. Most of the heavy posters on this forum (read: ones who help others a lot) use the view active topics or view new post link to see what needs to be dealt with. Multiple posts just flood the screen. It's a learning curve since this forum is a lot more helpful than any of the others I have ever used. And thanks for the blessing! :cool:

I'll add my thanks to you both for your confirmation of what I believe - that all Scouts have poor quality sound - Even though many folks post that their Scouts have equal call quality to their Hubs, I believe they are all mistaken.
However, like both of you, I'm very impressed with the call quality on my Hubs.

I have had the opportunity to hear both sides of phone conversations with my OOMA. I will say I am still very glad I woke up last Sunday and bought this thing. Crystal clear both up and down stream. So again thanks to everyone on this board for all the tips. And yes the scout in my opinion does not have the same clarity as the hub.

I have cable internet supposedly 10mb download and 1mb upload but I don't think I'm getting that much this time... I think it gets congested most of the time... Do you think DSL 1.0mb download and 387kbps upload will do the job instead of the cable internet? I'm planning to switch to verizon if that's going to work. Please help, right now I can't use the ooma because of that problem and it's gonna be waste if we can't do anything about this. Below is the other result I tested, this is around 1130 in the evening:

Those are horrible numbers.

There is something wrong with your internet connection.
How many splits are there between the incoming cable and the cable modem?
There should be no more than one split and the splitter must be a bi-directional splitter.

Turn off your cable modem.
Connect a computer directly to the cable modem.
Turn on the cable modem.
Wait for sync with your ISP.
Rerun the test.
Post the results.

I have no idea about that splitter. I can ask the ISP if you want. I only know that the cable internet is connected from the wall jack to the cable modem.
I tested that directly connected to the cable modem.
Can you explain more further what's the problem with my test results so I can tell them what's wrong. Is that normal with the cable internet? I plan to switch to verizon for 1.0mb download and 380+mb upload if this won't solve the problem, they have dsl connection. I'm not just sure if this can fix the issue.

Jitter should be less than 5 ms.
Packet loss should be 0.
Download and upload QOS should be at least 70%.
Maximum TCP delay should be under 100 ms.

Try this. Connect to the status web page in your cable modem

http://192.168.100.1

Find the downstream and upstream power in dBmV and the Signal to Noise Ratio (SNR) and report back.

The downstream signal power should be between -10 and +10 dBmV. (Some say between -15 and +15 but I feel that is pushing your luck)

The SNR should be 35 or more.

The upstream power level should be less than 55 dBmV.
