If you are using a Modem-Ooma-Router connection, you need to reset your Ooma Setup quality of service settings to match the new Internet speeds.runun wrote:I've had the Ooma Telo for over 3 years now and until 6 months ago, I only had a 1 Mbps (125 Kbps) upload speed and Ooma QoS never consumed more than half of my upload speed. Recently, my ISP (Charter) has cranked up their broadband speeds and I've now got 4 Mbps (500 Kbps) upload. Why does the Ooma QoS consume nearly all of the 4 Mbps upload bandwidth during a phone call? I thought Ooma used compression methods that only required around 30 Kbps. Currently, during phone calls, I've only got about 30 Kbps remaining out of 500 Kbps. BTW, I know these numbers because I can watch my torrent client during a phone call, and I can also watch my FTP server upload speed, as well.
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 of Phonepower test results window. 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.
But some people with a change of Internet speeds still have problems. If that happens, you may have to consider connecting Modem-Router-Ooma, and setting your Ooma Setup QoS settings to Zero.
In this configuration, nothing is connected to the Ooma device Home port, except temporarily connecting a computer to access Ooma Setup view settings and make setting changes.

Reducing the QOS numbers by 20% avoids that situation most of the time.
