A Modem-Router-Ooma connection has a simular or same function as a Modem/Router-Ooma connection.

Jitter server you ___6.2ms____.....This reading is should be less then 5ms.
Packet discards ____0.8%_____........This reading should be Zerro.

Overall MOS score is 4.1 which is very good. But often during different heavy overall Internet provider user times of the day, the Phonepower readings may become worse, if the Jitter and Packet loss is observed.

Usually when Jitter is high and there is Packet loss, the Modem is malfunctioning, or the Internet provider signal is defective.
Locate your Modem/Router Owner's Manual and see if there is a Reset procedure. If so do the Reset procedure per the Modem/Router Owner's Manual. If not do a Reboot of the Modem/Router.

Note: Some Modems contain batteries that must be temporarily removed to allow a successful Reset or Reboot, reference your Modem/Router Owner's Manual for battery removal procedure.

After the Reset or Reboot, run Phonepower again and see if your Jitter and Packet Discards readings improve.


Doing these things may not help to improve the One Way Calling Problem. So if it doesn't, be sure to contact Ooma Customer Service with that problem.

I have no idea what all this means or how to fix my call quality problems. I cannot go to http://172.27.35.1--my internet just doesn't go there. I did manage to get my firmware number 63430. To remedy my problem I disconnected the wireless ooma connection and used the cable to connect to the router. It seems a little better but not cured. Most of my problem is with my voice not the person I called. They say I sound underwater and can't be understood.

I don't know if I have modem-ooma-router or what connection. I just connected ooma to router and ooma to phone. I have a panasonic phone with 2 handsets. I just asked for an ooma handset for Christmas. Have only had Ooma since September and the call quality just deteriorated in the last 2 weeks. *sigh* I so want Ooma to work.


Setting MAC address In My Ooma:
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.

Quality of Service settings:
For a Modem-Ooma-Router connection.
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 connection.
Set Ooma Setup Quality of Service Settings, both to Zero. For this connection, if the router has QoS settings or can set VoIP priority for a device, then give the Ooma Telo top priority in the Router.

Quote from Ooma: Ooma is engineered for great voice quality but you will need a high-speed Internet connection equivalent to at least a typical DSL connection with 384 kbps upstream and downstream.

RedTennies: Looking at the numbers above, you problem isn't with the Ooma Telo, it's with the Modem or Internet provider signal.

Upload Speed of 101 kbps isn't a high enough speed to support the Ooma Telo. The outbound Jitter is much to high, and you shouldn't have any Packet loss or discards.

Check the modem owner's manual and see if there is a Modem Reset procedure. If so, per the owner's manual do a Modem reset procedure. If not do a Modem reboot, which is removing power from the Modem, then restoring power to the Modem.

Note: some modems contain a battery that must removed to allow a successful Modem reset or reboot. Reference the Modem owner's manual for battery removal procedure.

After the Modem Reset or reboot, run Phonepower Speedtest again. Make sure that the Upload speed is at least 348 kbps, the jitter is less then 5 ms, and their is no packet loss or discards.

If the Upload Speed is still less then 348 kbps, then contact your Internet provider and find out what your upload speed should be, and have repairs made or have the Upload speed increased, what ever is required. This will probably help the jitter and packet loss problem.
If the Upload speed comes up to at least 348 kbps, but the jitter is still high and there are still packet problems, the modem may have to be replaced??
