What is a VoIP-enabled router?

I came across an advertisement of D-Link's DVG-G1402S wireless router with embedded VoIP functionality. Does this router provide the same functionality of a traditional router and at the same time, allow you to connect an analog phone and fax machine to it if a VoIP service is engaged?

A router with embedded VoIP functionality is one with integrated Quality of Service, which is a protocol that gives priority to voice packets over data packets to ensure smooth VoIP calls. If the QoS is working well, you should expect to see data downloads and uploads slow down during VoIP calls. And yes, the router will also perform all the normal router functions, as well.

Normally, if you sign up with a VoIP service provider such as Vonage or AT&T CallVantage, the service provider will send you a telephone adapter, which you plug into your router. The adapter handles the QoS and houses the necessary hardware, including phone jacks. A VoIP-enabled router bundles all this hardware and functionality into one package, which makes for a tidy and elegant solution. Often, in retail stores, you'll find VoIP-enabled routers bundled with offers for VoIP service, too.
