I am optimistic in using OBi but will it work for me?
- Can I use google voice?
- Can Chilean numbers be able to call me, if yes... will they need to call my US google number or is there a Chilean number they will use?
- Are there other costs to making these calls (connection charge, etc)?
- What will the rates be?
- Do I have to use Google voice or skype or is this a standalone system?
(All rates below are in US$ per minute.)
To use the OBi, you need an always-on broadband connection (DSL, cable, fiber, etc.), with a modem and router having an available Ethernet port. You also need a standard corded or cordless phone.
The OBi does not include phone service; you can use it with a Google Voice account, with a SIP provider, or a combination of providers. According to
https://www.google.com/voice/rates?hl=en_US¤cy=USD , GV rates to Chile are $0.03 landline; $0.10 mobile (they may have raised rates since you saw the $0.02). You can find lower rates elsewhere, but the quality might not be as good, so you may have to risk a few dollars to experiment. With GV (and most other providers), there is no connection charge or other fees, you just pay per minute for the calls.
You can get an incoming Chile number for your OBi from several providers. There is a monthly fee, but no charge to receive a call. For example, an Anveo Personal Unlimited number is $7.50/mo. If you only need to receive calls from specific contacts (recognized by their caller ID), you can use Localphone or Rebtel to avoid the monthly charge.
The lowest cost providers are the Betamax companies
http://backsla.sh/betamax , though quality is usually not the best. For example, Easyvoip is $0.007 to Chile landline and $0.02 to mobile. Another inexpensive choice is CallWithUs, a small company with IMO better support. You might also look at Localphone and Voxbeam (two brands of the same company); both offer a small credit at signup, so you can test without making a payment.
You can also set up your OBi so you can call it from your mobile. You hang up before it answers and it calls you back. You can then place an outgoing call, which would allow you call at lower cost, when you are away from home. Who is your mobile carrier?
