Product Description

You must buy this if you want to expand your system beyond 4 lines and/or 8 phones. It extends about 12 inches to the right of the main control unit. We recommend ordering it with the starter package, for easier installation.

"Ground" shipping is free in the USA, only when ordered with a starter package or at least two Port Expansion Modules, or a Port Expansion Module plus an Internet Router Module.
