Let's see...
The OBi device (i.e. OBi200, OBi202, or other OBis)...bought 1-time, gets the following when Google Voice service is added and which Google Voice service is also free:
Outbound/inbound calls are FREE in the US/Canada.
No monthly charges.
No yearly charges.
Free call-forwarding to your cell phone (or others) with Linked numbers so you won't missed important calls.
Free to forward message to your Gmail email account so you can review.
Free get email alerts for missed calls.
You can screen calls before actually talking to the caller.
Send calls to GV voicemail by Do Not Disturb.
Has Voicemail greetings or record your own greetings and also manage greetings if you have multiple greetings.
And overseas calling with rates applied (low cost too).
Once in while a little hiccup, a little static here and there. "Hey, let me call you back" on this free Google Voice service with my OBi here. WOW.
And I have multiple OBi devices with Google Voice services and have not paid a phone bill for the last 6 plus years. Love it!
Paid that monthly phone bill (to Comcast, AT&T, others...?) or pay nothing. Hmmmm? Imagine Google Voice service (or Google, or Alphabet) deemed Google Voice service no longer needed and ends the service (again).
Btw, if you have not done so, update your OBi firmware here (free too)
