Absolutely correct. Please note the difference between numbers and lines. ooma currently only supports two lines. If you need four, you should get two ooma Hubs.cetacea wrote:I'm relatively new to Ooma, having just installed ours last week, but what I'm getting from my readings is that the Ooma hub, regardless of the number of Scouts attached, will provide a maximum of 2 LINES.
You can add up to 9 additional phone NUMBERS, but only 2 LINES can be active with an Ooma Hub. In other words, if both lines are busy, and you have 2 additional phone NUMBERS, they would be sent directly to voice mail.
The only way to have more than 2 LINES is through the addition of yet another Ooma Hub. I believe I came across a few threads discussing the setup of 2 Ooma Hubs, one downstream of the next.
It would be interesting to know if both, the First In or the Last Out, would have to configure the DMZ for the router downstream.
You cannot have two ooma Hubs using the same phone wiring to connect ooma Scouts. Most newish homes and offices should be pre-wired with two pairs. You can run one ooma system on one pair (line 1) and another ooma system on the second pair (line 2). A simple L1 + L2 splitter from Radio Shack makes it easy to access either pair.
You can daisychain Hubs. I would see if you really need the QoS in the Hub. If you don't, it may be simpler to put the Hubs behind the router. If do end up daisychaining them, you should change the LAN subnet of one of the Hubs. Otherwise the second Hub will have both the WAN and LAN interface on the same subnet and the box will be confused.
