I'll try to make this NOT put the reader to sleep as it is overly long and goes from the ridiculous to the absurd...
Given that a shiny new wired Ooma costs ~$100, that was a non-option for us, and we got the way cheaper used one via fleabay...and as told before, it didn't work for some unknown reason, not no way, not no how - so they told us they'd send out a new one - pretty good of them, IMO.
In the meantime I asked them if they could confirm that their service was OK with comcast service, and they insisted that it works 100% fine with our ISP & our (cheapest level) internet only service.
The free (new !!) replacement arrived - and it didn't work here either - and all of this ate up serious amounts of time with their phone people - who ultimately sent out yet ANOTHER new box for free - wow.
The 3rd box came & it also refused to work.
Not wishing to spend even more of my life having non-discussions with their folks who clearly had no clue why these things utterly refused to work - I tried LOTS of stuff, and - also located a cheap, but new Ooma wireless USB adapter & ordered it (they are discontinued now, BTW...).
Meantime - I was very, very baffled as to why 1 used & 2 new Ooma boxes would not respond here in ANY way as they were supposed to.
Lucky for me, our neighbor also has comcast & I was able to connect the newest box directly to his modem/router - and guess what ?!?
It cycled up & got to the blue mode, meaning it was all ready to make calls (I had no phone with me).
Came back here & connected it - nope, a total no-go...again.
So I got a bit creative and imposed a switch (like a network hub, but better) between our cable modem & the rest of our home network - hooked up both the Ooma ethernet connections to that as well as a separate PC to try and contact the Ooma's internal server (setup.ooma.com or 172.27.35.1) and it was a total non-response as well...UNTIL=>
Just for yuks, I removed the 'internet' RJ45 - and holy cow - the setup page came right up !!
Went through ALL of its pages & options & gave it a static IP address so as to use the cable modem directly, and after a restart it still responded, but still could not make the needed Ooma stuff work to get their services.
(It did show as having an active account with the correct number too.)
Tried the same procedure with the prior new box as well as the used box - did ALL the same settings changes - and they worked for their internal server contact as well...only.
A day or so later the wireless adapter arrived - and after a prolonged boot-up time, that was able to see both our wifi as well as the next door neighbor's - and amazingly, once the ethernet connection was removed - the latest box went 'blue' via wifi only...Wow !!!
Feeling quite optimistic, I unplugged it, moved it across the room, and powered it up again, and waited and waited and waited - but it stayed 'red' - another no-go.
Pulled it (GROWLING !!) crossed the room and plugged it in there & waited (coffee time...) came back, and...'blue'.
Woof - WTH is going on here ?!?!?!?!?!?
Diagnostic mode engaged - so, what is different from this, to 6 feet away, really ??
Checked everything until finally looking at the wall-wart which had come with the used Ooma - 5V (check), 400ma...huh ??
The Ooma boxes require 5V 3A - which the new one came with, whereas I'd left the original wall wart plugged in as it is in a nasty spot to reach - so I changed that, and what happened ??
Boot up followed by solid 'blue' & working 100% for calls in & out.
Conclusions after all this absurdity:
1 - Minus the correct PSU the Ooma will start & -appear- to run, but isn't getting enough Ooomph to work 100%;
B - The weaker PSU could not power the wireless USB either;
3 - Our cable modem, a Motorola SB6121 isn't allowing...something through that Ooma needs, even though all other devices get along with it just fine.
Since the Ooma folks told us that the other devices are now 'blacklisted' and can never again be used - I pried open the used box - and now I see why these can be given away so freely - it is merely an SBC with very few components, the sort of board that gets outsourced & maybe cost ~$10 each to get in hand & all the rest is a glued together plastic case, the PSU & a cheapo patch cable.
Selling these for ~$100 must be very profitable is my guess, and now that they have the wireless model for even more & a 4G model too, they likely have plenty of these on hand to keep their customers happy.
So we finally have a working Ooma for a cost of under $5/month with 2 numbers (non-premium) 2 useless boxes to toss out, and an extra PSU in case the other one fails.
Based upon al the above - are we happy with this ??
Except for the time wasted upon getting non-answers from folks who know too little about what they support...
At some time in the future I will consider getting an updated Arris cable modem/router with wifi as good models can be had cheaply - but that can wait as it is another spend that we can do very well without right now.
(Have I put anyone to sleep with all that ?!?)
