Upstream and downstream.

One is called upstream and the other downstream. When you talk, the Oama turns your voice into a digital signal and sends that upstream over the internet to Oama where there connect you to who you want to talk too. The other is when you hear the person on the phone there voice is coming downstream to you.

If you cant here the other person then you have a downstream issue. Call your internet provider. You can probably browse the internet but the page or website your going to comes in a bit slow.

If the other person cannot hear you then you have an upstream problem.
Call your internet provider. You can probably browse the internet but might take extra time for your request "name of website" to register and send you the page.


You could also experience both but then you would have really slow internet and voice quality would just be horrible. Could be almost anything being the issue. Be it your internet provider, ooma hub, modem, router, cat5 cable, you name it and it could be the issue.

Upstream and downstream work on different frequencies from the cable company if thats your provider.

So just an FYI. I am new to Oama but I am a 12yr Communication Specialist for Time Warner Cable. I have installed phone and internet for 10yrs. if you have any question post them here and i will do my best to help out.

Glad to see someone on the board who works for TWC.

Here is my problem. I have a Linksys WRT320N router and am running a home server. If I place the Ooma behind the router, then the router, I'm not able to get out on the server.

If I place the router behind the modem and then the Ooma, the voice is really bad.

I set the router to give Ooma the highest Qos and placed the Ooma in the DMZ.

Any suggestions would be greatly appreciated.

If you have a server, its ip have to in the rourter dmz, otherwise it becomes unaccessible from the outside. If the ooma hub is in front of router, the router have to be in the hub dmz too, in order for it to work.

My ooma is behind router and I do not dmz the ooma though. However I have the router doing QoS. If you plan on place ooma behind router, you need to setting up QoS for ooma in the router. QoS setting vary from router to router.

My router is an Airlink 101, and it does QoS base on ip and port #. Note that ip have to be static (which Airlink supports.)

Some one might be able to help with QoS on Linksys, and I'm not sure if the dmz will interfere with QoS. Just for trying, put your server into router dmz and review QoS setting of your router--some screen shot sure will help others help you.

AWESOME! I'm glad you are part of the Ooma family now. There are several cases where our instincts tell us the problem might be a cable internet problem, but we don't know enough about the specifics of cable to help isolate the exact cause. There is a great deal of networking and phone experience around here, but the hands on experience you bring is one of a kind.

Welcome to Ooma!

Cheers,
Scott

Sounds like tommies is on the same path I would take. Let us know how it works out.
