Installation
The DVG-3104MS Gateway translates incoming phone calls so they
can be sent over your organization's LAN, and translates outgoing
calls into the format used by traditional phone service.

VoiceCenter . If you have an alternative jack available, use it to set

up and test the VoiceCenter phone system.
Plug the power adapter into an AC outlet or power strip and plug the
other end into the AC input on the back of the gateway. The power

back of the gateway and connect the other end to a phone jack.
