The NetComm V220 VoIP Telephone Adaptor has been designed for residential and small business users to deliver predictable, real-time voice quality over the internet. It connects directly to any broadband modem and service (cable or DSL) plus an account with a VoIP service provider. A standard analogue telephone (desktop or cordless) is connected to the FXS (phone) ports on the back of the V220 ATA, allowing the user to route calls over the internet to anywhere in the world – using VoIP, significantly reducing or even eliminating long distance call charges.
