Hi,

I recently purchased a DOCSIS 3.0 modem for home and installed it. After the installation, I tested the download and upload speed (20Mbps download / 11 Mbps Upload)

When I place using Ooma phone - the upload speed reduces to 2.8 Mbps. This also shows when I talk over ooma and browse a web page - I will hear voice becoming choppy, both sides cannot hear each other for some seconds, and then it will recover.

Ooma is connected directly to Cox Modem and Wireless router is connected from the Ooma telo hub.

Any ideas?

Thanks

Did you configure QOS in the Ooma setup pages?

Procedure for setting Quality of Service for Modem-Ooma-Router setup:
Access the Ooma Setup by typing http://172.27.35.1 in your computer browser window. Click on the Advanced tab. Under Quality of Service set both the Upstream Internet speed and Down Stream Internet speed to 80% of the measured Upload and Down load speeds as measured by http://www.phonepower.com/speedtest. After running Phonepower Speedtest, click on the Advanced tab at lower left side. Take the Download Speed and the Upload speed, and multiply .8 times for each number. The resulting numbers are the numbers that you enter into Ooma Setup, Advanced page under Quality of Service Upstream Internet Speed (kbps): and Downstream Internet Speed (kbps): boxes. Click on Update. Then test making and receiving calls.

Something else you can do to help stabilize your Ooma device:
Change MAC Address from Automatic to Use Built In.
If your Ooma device is connected Modem-Ooma-Router, access your Ooma Setup pages by typing http://172.27.35.1 in your computer browser window. The Ooma Setup pages open. Click on Internet, go down to INTERNET Port MAC Address: and change setting from Automatic to Use Built In. Click on Update device. Remove power from your Modem and the Ooma Device. Repower the Modem. When the Modem is done booting repower your Ooma device.

If your connection is Modem-Router-Ooma, temporarily connect a network cable from your Ooma device home port, to the wired LAN port of a computer. Temporarily turn off Wi-Fi in the computer, if turned on. Reboot the computer. Access your Ooma Setup pages by typing http://172.27.35.1 in your computer browser window. The Ooma Setup pages open. Click on Internet, go down to INTERNET Port MAC Address: and change setting from Automatic to Use Built In. Click on Update device. Remove power from your Modem, your Router and Ooma Device. Repower the Modem. When the Modem is done booting repower your Router. When the Router is done booting, repower your Ooma device.

Next:
You could also try connecting Modem-Router-Ooma. When people connect using this configuration, nothing is connected to the Ooma Telo Home port, except to temporarily connect a computer to access Ooma Setup.
For this type of connection Ooma recommends that the Quality of Service settings be set to Zero.
