Telo is between my cable modem and wireless router as advised.
Updated QOS Upload bandwidth as recommended 80% of reported speed.
My voice still breaks up on phone calls though I can hear out fine. I am on my last thread- I am about to return this device. had it for less than a week.

Results for http://speedtest.phonepower.com/.... to see how your modem and Internet connection is doing. Then click on the Advance tab on the lower left side of the Phonepower page, and post the following values here in this thread, by clicking on "Quote" in the upper right hand corner of this Ooma Forum post. Then fill in the blanks.

Download Speed: 10.2Mbps
Upload Speed: 393kpbs
Download Consistency of Service 14%
Upload Consistency of Service 7%
Maximum TCP Delay 796ms
Jitter you server 112.6ms
Jitter server you 4.8ms
Packet loss: you server 2.2%
Packet loss: server you 0.2%
Packet discards 22.6%
Packets out of order 0%
Estimated MOS score 1


CONFIRMED: my MAC address setting, in Ooma Setup, uses Built In MAC address.

Completed the following test: Please help.
Next Set the Ooma Telo Ooma Setup Quality of Service Upstream and Downstream Internet speeds both to a value of about 1000 kbps higher then the measured Upload and download speeds as measured by Phonepower Speedstest. Then test.

You have serious problems with your internet connection.

PD3:
Your Modem or Internet signal (wiring coming in from the street) has a problem.

Try removing power from your modem and wait for 5 minutes. Then repower the Modem and test again with Phonepower Speedtest. If that doesn't help, see if your Modem has a factory reset, reference the Modem owner's manual. If so do a factory reset of the Modem, the test again with Phonepower Speedtest.

This is what you have and I've added the values of what Phonepower Speedtest should be reading.
Download Consistency of Service 14%........................Should be around 80%
Upload Consistency of Service 7%.............................Should be Around 80%
Maximum TCP Delay 796ms.....................................Should be around 100ms or less
Jitter you server 112.6ms......................................Should be less then 5ms
Jitter server you 4.8ms
Packet loss: you server 2.2%...................................Should be Zero
Packet loss: server you 0.2%...................................Should be Zero
Packet discards 22.6%...........................................Should be Zero
Packets out of order 0%
Estimated MOS score 1.........................................Should be around 4.0

Both the upload and download consistency of service are very, very poor.
The Max TCP delay is really poor.
Any dropped or out of order packets are always very, very poor.

1. Remove power from your Modem, Ooma, and Router. Using a network cable, temporarily connect your computer's wired LAN port directly to the Modem, leaving the Ooma device and Router temporarily unpowered and disconnected. Repower your Modem. When the Modem is done booting, repower your computer.
Run Phonepower Speed test again.

2. If you still have poor test results, check for any splices, splitters or poor condition cable coming in from the street, to the Modem. If you find questionable or loose splice connections, loose splitter connections, or poor condition Internet cable, coming in from the street to the Modem, correct those conditions, and test with Phonepower Speedtest again.

3. If the above test passes, remove power from the Modem and computer. Connect Modem-Ooma-Router and test again using Phonepower Speedtest.

4. If you have problems again, connect Modem-Router-Ooma. With this connection, nothing is connected to the Ooma Home port, except temporarily a computer to access Ooma Setup. Connect the computer to one of the Router LAN ports, with Wi-Fi temporarily turned off in the computer, if Wi-Fi is turned on in the computer. Repower the Modem. When the Modem is done booting, repower the Router. When the Router is done booting, repower the Ooma device. Repower the computer, and test with Phonepower Speedtest again.

5. If you still have poor test results, if you are renting your Modem, get the Internet provider to give you another one. Otherwise purchase a new modem and test again.

If that still doesn't help, contact the Internet provider and report their poor Internet signal.
