Simply connect the Quadro16x to a broadband Internet service or to your company’s gateway router. Next, connect up to 16 ordinary phones and fax machines to the Quadro. In minutes, you are able to make VoIP calls for free. The Quadro's voice quality will almost always be better than using your long distance company.

In addition to its Voice over IP capabilities, the Quadro16x has a host of features for the small business. With its built-in IP router, you can create a firewall protected computer network. In addition, you can establish a highly secure VPN from the Quadro to other Quadros or to the corporate office.

The PBX features of the Quadro like voicemail and auto attendant give you all the phone features you would have at any large corporate office. The SIP voice over IP gateway with STUN allows you to connect to other Quadro users or a SIP server to make virtually free long distance calls all over the world. All this functionality is in one small appliance. To ensure optimal uptime for your business, the Quadro’s FXO port will automatically engage one of the phone ports to provide lifeline support in the event of a power outage.
