Can't say enough good things about Ooma.
I know you like Ooma, Hawkeye, but there's a reason why I don't recommend them, and it comes down to math and features. Let me do the math breakdown for you and others on Ooma's costs and features for their "free" service:
$160 Ooma Telo purchase
$39.99 for number porting (optional)
$3.75/month for taxes and service fees (average)
TOTAL BUY-IN COST: $200
TOTAL COST PER YEAR: $45
That's for their "free" service. If you want any of the features they offer on their "Premier" service (free calls to Canada, number roll-over on device failure, Caller ID name, anonymous call block, voicemail forwarding to e-mail... basically
free services with nearly any other VoIP carrier), it's an extra $10 a month. I might also add, most other VoIP providers will number port for free.
TOTAL COST PER YEAR FULL FEATURES: $165
Also, your expensive hardware's locked into Ooma. You can't use it with another SIP account, nor can you use Ooma with your own ATA. If the hardware fails (which it's known to do due to cheap capacitors), you're buying another $160 Ooma Telo. If you decide to switch elsewhere, you're buying or renting new equipment.
Now, let's compare that with VOIPo and their normal running deal:
$0 hardware costs (provided free)
$0 number porting fee (provided free)
$7.71/month for service, taxes, fees (average with $149/2 year deal + taxes)
TOTAL BUY-IN COST: $0
TOTAL COST PER YEAR: $92.50
It would take
FOUR YEARS just to break even on the cost of Ooma's
free service over VOIPo, and you wouldn't even get half the conveniences VOIPo would provide or the freedom and flexibility of having a standards-friendly SIP provider... and that's assuming there's no hardware failure in those four years. Both services cap at 5000 minutes a month, so there's literally no advantage... though VOIPo at least charges you for the overage instead of potentially terminating your service.
How's that deal look now?
I don't point this out to insult or belittle pre-existing Ooma users... if you've got the service and you're happy with it, fantastic. I mainly point this out for people who might consider buying into Ooma without thoroughly researching first figuring it's a fantastic deal when it really isn't by competitor's standards.
If you want
dirt cheap phone service with a proprietary device and no SIP device support, you're far better to use
NetTalk. All the premium features with Ooma for free at a fraction of the cost. $45 for the device and a year's worth of service, $20 number porting fee, $30 a year after for service. Ooma can't touch it except in call quality, but even the voice quality with NetTalk is more than serviceable (and moderately better sounding than MagicJack).
