Intermittent Poor Call Quality (Garbled, Digitized Voice)

Post by ChrisZ » Wed Dec 19, 2012 9:09 am

I frequently have a problem where the incoming audio becomes garbled or digitized. This is on a Time Warner Cable Business Class connection of 15Mbps x 2Mbps. The Telo and a couple of servers are are connected to the cable modem, each with their own static IP address. I do not want the Telo being the router for my network. That's my server's job. Here are my speed test results:

My Telo was set to 0 for download and 384kbps for upload. I set both for 128kbps and will report if this solves it. I know there are at least a few others experiencing the same problem.

ChrisZ:
To help stabilize your Ooma Internet connection turn off MAC address Spoofing, which can cause dropped calls, garbled voice, and other problems, by doing the following:
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 or 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 (or Modem/Router), your Router (skip to Ooma Device if have Modem/Router) and Ooma Device. Repower the Modem (or Modem/Router). When the Modem is done booting repower your Router (skip to Ooma Device if have Modem/Router). When the Router is done booting, repower your Ooma device.

For a Modem-Ooma-Router connection only:
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.

For a Modem-Router-Ooma Conection Only:
Set the Ooma Telo Ooma Setup Quality of Service Upstream and Downstream settings both to Zero.

I hope you can help me with the changing of the Port MAC Address to Built in. I don't seem to be able to access the Ooma using the 172.27.35.1 address. It just doesn't connect. My Ooma is connected to my wireless router. I tried connecting the Ooma directly to the computer but it didn't connect. Anything I need to do different? Appreciate any help.

When you connect your computer directly to the Ooma "home" port, turn off wifi on the computer and try http://172.27.35.1 again (or http://setup.ooma.com). Trying once or twice, if it doesn't work, keep trying. With a different browser too.

Make sure that your computer Local Area Connection isn't using a Static IP address.

Procedures for changing to Automaic IP address at the following sites.

Thanks, I finally got it to work. So far so good with the garbled voice problem. Now I can start my phone number port.
