Couple Of Questions

[TreatnHerRight]

  I currently have a Comcast land line and a set of wireless home phones.
I would like to know which Obi to buy to be able to have both my Comcast land line and my Google voice account which will be used for international calls to be sent to my set of wireless home phones. Also how would i go to set this up? And if its not possible please let me know.

Thanks,
TreatnHerRight.

OBi110 is the only one that can hook to your Comcast line.

You could port your Comcast number later, but the OBi110 could still support that too.

That has changed.  The Obi2xx series can now do this with the new adapted just announced.

The Obi110 remains the only Obi device that has that feature built in but if you want additional features like two lines and cell phone BT connections you do have options.

You should look at this for a side by side comparison.

Connection to the Comcast line with the Obi202 or Obi200 would require an adapter.  The Obi110 does it natively and is the least expensive option if you want to keep Comcast.
