How to install Ooma in a house with multi-jack on two levels

[chris650]

Please help.

You would use a cordless phone that has multiple devices, or plug a different phone upstairs in a Ooma Scout

Would pluging the ooma hub "phone" jack directly into an existing house jack solve the problem? If like most houses all the jacks are tied together, then, theoretically this would supply ooma phone service via back-feeding to all of the jacks.
Maybe??
