Looking at the OBiBT device, and it appears it makes your cell phone service usable in the same way as if you had a landline connected to a Line port on an OBi110. So, why not make a Line port adapter for the OBi202 that would plug into the USB port? It could come in a package similar to that of a USB 56K External Fax Data Modem (look one up on eBay) as used with a laptop computer.
This would make the OBi202 so much more useful for those that still happen to have landline service.
