Smithtown, NY | ooma questions
I note you mentioned setting it up behind the router. Any advantages to doing it this way?
Curious what happens if you get a new DHCP address when your modem resets? Or perhaps change providers? |

1 edit |  Placing the Ooma hub behind my router allowed me to put it where I wanted it physically. My modem / router are in a rarely used closet. I wanted the Ooma hub where it could be seen and used. The Ooma hub has indicators, and controls on it, which should be proximal to where people can see and interact with it.
The Ooma hub is currently using an alternate set of phones, distinct from my normal home phones. This to permit testing. In a few weeks, I'll probably port one of my phone numbers to Ooma and it will drive my normal home phone system.
I have set the Ooma hub to a fixed LAN address via static DHCP, using the Tomato 1.23 firmware on a Linksys WRT54GL router. The static LAN IP address is controlled by the Ooma MAC.
My Ooma is set to highest QOS priority via its MAC.
My PAP2T is similarly set.
Today, I bought and activated a 2nd Ooma core (hub + scout). Both work fine behind my router, each has a LAN static IP address, each gets highest QOS service. I can call from one to the other and get very high quality (voice) calls.
Ooma has been 100% reliable, and hasn't used much bandwidth. If my public WAN IP were to change, it wouldn't affect my Ooma devices. They would still be highest priority QOS on my LAN. Their LAN address can't change as its controlled by my router and is set to static.
I used to have two AT&T lines, and am now planning to go to none by the end of this summer.
Currently I have 4 VOIP connections running 24/7 on my LAN. 2 to Ooma, 2 to Future-Nine. I have moved one AT&T phone number to Future-Nine, and have one to go.

Smithtown, NY | Your reply is a bit more technical than I am able to easily decipher. Is there an end benefit to connecting the hub to the router as opposed to the cable modem?
Any consequences were I to change providers? |

| I apologize.
A reason to put the Ooma hub behind the router is to keep it proximal to the area it will be used in. My router and cable modem are in a closet remote from where I want my Ooma to be.
Placing the Ooma behind my router, permits me the ability to have it physically where I want it.
Additionally, I don't have to worry about Ooma being in the way of, or managing any of my LAN -> WAN traffic. Instead of sitting in the middle of everything going to and from internet, my Ooma hubs sit on the inside of my LAN only generating traffic they need to manage VOIP calls.

Smithtown, NY | What happens if a power failure causes my modem to reset with a new leased IP address? Or, if I were to cancel my current provider and move to a new broadband provider? |

Outland | The Ooma hub will re-establish it's VPN within a short period of time. |

There is an advantage to connecting the ooma unit between the modern and router. The ooma unit has its own QoS control. When placed between the modem and the router you can be assured that ooma will get all the band width it needs. It is just a little more Plug-n-Play that way.
Mine is also connected to my router and I did that only because when it was connected to the modem it acquired a strange IP address and I became alarmed that my ISP was also see it as a second device on their system. I have since found out hat the ooma unit will acquire an IP address and DNS address from ooma at least that is the what I believe was going on and why I saw a WAN address assigned to my ooma when connected to the modem. It is a pretty tricky little box, all designed to make your life truly P-n-P. (I don't know about you but I sure love to plug and play, feel free to take that anyway you choose)
Short story - it works fine either way and per ooma only requires about 47 kb-ps of band width. |
