Whats the difference between the ooma Hub device and the ooma Scout device?
The ooma Hub device is the brains of the ooma system and must be installed for the ooma service to work. The ooma Scout device extends the power of ooma to other areas of your home. It also gives you access to the Instant Second Line feature (part of ooma Premier). Simply connect the ooma Scout device to a standard phone jack, a power outlet, and a regular home phone.
