Do I Need Any Other Hardware?
From PhonePower Knowledge Base
You will not need any extra network hardware to use our service, just the phone adapter device. If you already have a router, you can place the phone adapter before the router. You will plug the phone adapter into your current Broadband Modem and it will connect directly to Phone Power's servers (No matter what type of Broadband you use: Cable, DSL, etc.). For additional information how to configure your specific make and model of router or modem/router combo, please refer to our Customer Provided Routers section.
