I've never had "one-way" problems. What does your delay currently measure using 909-390-0003 and Audacity?

It took me a while to find a mike and hook it up to hook up to my computer.

This morning I'm measuring a little less than 300 ms using 909-390-0003 and Audacity.

What is your ping time to www3.ooma.com?

Ping: Min = 107 ms, Max = 125 ms, Average 111 ms

This was Pinging using a computer with a Wi-Fi connection.

Your delay (less ping) is 190 ms vs my 320 ms.

I wonder if Ooma has the ability to configure individual user's play-out buffers longer or shorter? This may be what they did for you to reduce your delay. Shorter buffers may be prone to robotic voice caused by buffer underflow due to jitter. I've never had robotic voice issues.

It's fine. I hope this helps others having delay or echo problems.posting.php?mode=reply&f=4&t=11377#

After you reboot your home's LAN equipment and your Ooma phone conversations improve, you were probably experiencing half-duplex conversations. Ooma needs full-duplex to operate correctly. Rebooting usually returns the equipment back to full-duplex operation.

When you can find some time, some interesting reading below about half-duplex and full-duplex.

The normal order for booting a Modem-Ooma-Router setup is to remove power from the Modem, Ooma device and the Router. Then repower the Modem. When the Modem has completed booting, repower the Ooma device. When the Ooma device is done booting, repower the Router.

I have had voice delay issues for several months without a resolution.
My delay is both ways: 1-2 seconds. Lately now I have been getting some echoing at the very beginning of a local call. Locals calls appear to be worse than long distance. (I'm in northern Indiana).
My carrier is Choice Communications. I am at wits end. I have spent hours on the telephone with ooma tech support and Netgear tech people. Bandwidth and modem, router not the issue. My setup is working better than it ever has but certainly not even up to the basic level it should be. I am tired of apologizing to callers for talking over them so now I make sure that they know I have Ooma service so they don't get stuck with the same less than exceptable quality of service. I just asked to downgrade to basic from premier service because I cannot see paying the extra for the QOS I have been experiencing but if I lose my voicemail due to the QOS issue I will not be very happy!. Never had an issue with my last VOIP provider: didn't have to do a thing and got exceptional QOS. At this point I think it is all in Ooma's hands; there is nothing more I can do.
