Having voice quality issues with your Ooma?
First, see if your high speed internet or modem is having issues.
Do an internet speed test to see if you get expected numbers: http://speedtest.net/
For example, if your upload speed is supposed to be 2 Mbps, you shouldn't be getting 300 Kbps. Same thing with download; if you expect 20 Mbps, you shouldn't be getting 700 Kbps.
But speed isn't the only component at play for VoIP to work nicely so....
Also, do a VoIP quality test: http://www.phonepower.com/speedtest
Note: check the "Advanced" tab
If test results look bad, you have a problem with your high speed internet. It may be your modem or internet wiring coming into your home. Note: modem problems could be intermittent so test results may not be consistently bad; also, some folks experience high jitter and TCP delays if subscribed to "lite" versions of internet services.murphy wrote:Jitter should be less than 5 ms.
Packet loss should be 0.
Download and upload QOS should be at least 70%.
Maximum TCP delay should be under 100 ms.
If you have a cable modem, check some readings:
If your modem numbers look questionable, do a “restore factory default” on the modem status page & reboot or do a hard reset if the modem has a reset button. Problem may also be too many cable splitters between incoming cable and the modem.murphy wrote:Connect to the status web page in your cable modem
Find the downstream and upstream power in dBmV and the Signal to Noise Ratio (SNR)…
The downstream signal power should be between -10 and +10 dBmV. (Some say between -15 and +15 but I feel that is pushing your luck)
The SNR should be 35 or more.
The upstream power level should be less than 55 dBmV.
If test results look bad and your ISP can't fix it, swapping your modem to see if things improve might be a good idea.
If you previously had cable phone service and you don't anymore, the cable modem you are using with built in components to provide cable phone service may give you voice quality issues when using Ooma. Change the cable modem into your own and save $7 to $10 a month to boot.
If your internet seems to be okay, make sure to setup your Ooma using Optimum Installation Settings:
If before router: viewtopic.php?t=9536#p66155
If after router: viewtopic.php?t=12403
No matter where your Ooma is placed, if setup.ooma.com "Quality of Service" section has and entry "Reserved Bandwidth for Calls (Kbps):" set it to 215 instead of the default 130.
Note: If you connect your Ooma device behind the router, disable the Ooma upstream QoS by setting "Upstream Internet Speed" to 0 but still use "Use Built in Modem Port MAC address." You might want to setup router QoS if available (by Modem Port MAC address or Ethernet Port #). You may also have to deal with router firewall settings; see link below.

Start from "Reboot all of your devices"; of course, substitute "Vonage device" with "Ooma device."
In the "Other Possible Audio Issues" section, outside of "Do-It-Yourself Home Wiring Guide (Vonage completely botched it up for DSL users)," you can look up more information on distributing Ooma dialtone throughout home: viewtopic.php?t=6853 and https://www.ooma.com/app/support/distri ... hone-jacks and viewtopic.php?t=13354
