Thanks For your offer. I would be testing, except I've never had the Robotic voice sound.
Remember that you will need the time and patience, and there are no guarantees.
For these settings, it doesn't matter if the connection is Modem-Ooma-Router, or Modem-Router-Ooma.
There are two things that may be worth trying.
One would be to set your Ooma Setup Quality of Service Download Speed to double the measured download speed as measured with
http://www.speedtest.net/. This setting should make sure that there is no bandwidth restriction?
If that doesn't work, try setting the Ooma Setup Quality of Service Download Speed to 385 kbps. That speed is what Ooma says is the Minimum required for the download speed.
If the Inbound voice sounds garbled, but not robotic, increase the Download Speed by 5 kbps, and test again, etc.
If you think you are seeing improvement, but it seems like you are over shooting for this adjustment, try increasing the Download speed by 1 kbps, and test again, etc., etc., etc.
If the Inbound voice sounds Robotic, decrease the Download Speed by 5 kbps, and test again, etc.
If you think you are seeing improvement, but it seems like you are over shooting for this adjustment, try decreasing the Download speed by 1 kbps, and test again, etc., etc., etc.
These settings may slightly restrict the download speed, helping to keep packets in order?
Please report your findings.
