A:AnswerAbsolutely YES. You have to pay Ooma a small fee to have the number ported over. I have done this and know several other people that have already done this.
A:AnswerDon't know about talk time, but off cradle will depend on how you set up the "display" time out. If it is set to never turn off the backlighting 75% of the charge will be used in about 5 hours with straight from the box batteries it comes with.
A:AnswerQuality is fine enough depending on internet connection speed and latency. There may or may not be delays for slower connections or long latency. Volume IMO sucks.
A:AnswerYes. We r using our 10+ year old phones and the Ooma hd3 handsets. They all work fine (except the Ooma handsets have a lot of additional nice features).
A:AnswerI have used my Ooma for faxes with a fax machine using the telephone cord.
If you want a dedicated line for faxing, Ooma has a paid plan that adds a 2nd line to your account.
A:AnswerYes it is $40 for the one time fee of porting your # if you just want a basic service that is roughly $6 per month which are just fees and taxes.
Otherwise you can sign up for premium service for free porting of your # with the premium service cost per month of $10 plus the basic fees and taxes of about $6 for a total cost of approximately $16 per month.
A:AnswerAbsolutely YES. I have 2 Ooma Telo's connected directly to corded phones as well as connected to cordless phones and I have no problem whatsoever.
A:AnswerYou only pay taxes per month. Ooma has a calculator on their website where you enter your zip code and it will show you what the taxes are for that particular zip code.
A:AnswerThis is my own question. The anwer is yes! It works great. The Ooma box has a phone and ethernet connection, which i used to connect the CapTel brand phone to. I use Ooma handsets for the rest of the house.
A:AnswerNo. But you only have to pay government-mandated fees and taxes, and you must have internet service, of course. I do find their handsets to be somewhat clumsy, compared to standard cordless phones.
