I currently have the following:

Modem > Ooma Telo

Yes, that is it. Here is what I would like to move to now:

Modem > Router > Ooma Telo

Details on Modem:
(1.0 Mbps down/128 kbps up) - as advertised by cable company.

Details on the Router:
DDWRT running on Linksys WRT54GL

That said...

I would like to do the following:

1. Set a static IP for the Telo outside the DHCP pool (or range) allotted by the router's DHCP server. I know how to do this.
2. Set QoS values for the Telo. What are the values (I know how to set the QoS values (I think) to be used on the router?

From my reading on this forum, I see QoS is a hot topic. I would love a "straight" answer on this. If you can't give exact values, then give me the logic in coming up with values so I can tailor the values to my setup.

Also, if there is additional configuration I should consider, please simply list that, as well. If you want to get into details on it, that is fine also.

Thank you in advance.

You want the Telo to have the highest possible priority and nothing else to have that priority.
Everything else can slow down or stop while you are on the phone.
Delayed or discarded voice packets mean your conversation will be distorted.

murphy/thunderbird - thank you both for assisting.

thunderbird - Re: the down/up speed of my connection. I have been running with Ooma traffic alone and the call quality has been just fine, according to the caller on the other end.

I realize my connection is paltry, however, I assume QoS will "hog" the bandwidth when necessary.

I will record values throughout the day as you suggest and report back.

Ooma suggests that you have a minimum of 385 kbs download and 265 kbs upload.

It's good that your measured download, 1080 kbps and upload speed is 130 kbps, is a little better than advertised by cable company. But you still could have quality of service problems because of the low 130 kbs upload.

But you could just continue to use Ooma and see what happens. If you do have problems, you may have to have your Internet provider increase your bandwidth.

Fist if all your computers will be connecting wirelessly (rather than being hard wired to the router) you should not have to mess with the QOS settings on your DD-WRT router. The hard-wired clients will always take priority, out of the box.

I would not set QOS until you tested your service without setting it up, chances are you won’t need to set it up unless, you’re a heavy network user with DD-WRT

Not related to Oooma, you Defiantly Do want experiment with turning on after burner and Frame Burst (dd wrt wireless settings) to dramatically improve your wireless connection. Turn one on test the speed of your wireless clients, now turn it off and turn on the other, test, turn on both test. Also only use wireless channels that don’t overlap (1, 6 and 11) use the least popular one of those channels in your neighborhood. Also if you only have G clients change the broadcast to only G, it mixed mode there is alot of overhead.

Finally DD-WRT can be overwhelming until you get use to it and Google what all the different features do. If your router supports it, you may want to check out these projects as well (better GUI, built in Print Server for routers with USB ports, less granular in terms of what you can configure) (better GUI No built in Print Server) less

Since Ooma uses a VPN tunnel, a hacker would have to hack Ooma's security, before they could reach your router's LAN, and than to Ooma Setup. I'm not saying it couldn't be done, but very unlikely.

That's the same reason they say that if you put a computer in your router's DMZ, you should have security software on your computer for it's own protections. Ooma uses VPN for it's protections.

To make this work, you must always reserve a static IP address, in your router, for your Ooma device. That way the IP address that is in your router's DMZ, will not be assigned to any other device on your LAN. Because if another device on your LAN doesn't have security protections, connected to the IP address in the DMZ, it could provide an entrance to your LAN through the DMZ.
