As well as using existing analogue telephone handsets to make calls, it also provides a failover port to a traditional telephone service.

The DVG-2101SP's phone port relays outgoing phone calls to a public switched telephone network connection in case a power outage occurs or when an internet service is not available. This is said to guarantee that a phone connection will always be available. An LED display informs users if calls are being made over the internet or PSTN.

It supports many useful functions such as call transfer, caller ID display, three-way conference, phone book, spread dialing and hot lines. The unit also supports VLAN, which means the network is segmented to isolate voice communications so they cannot be tapped into.
