1. Introduction
1-1. Product Overview
D-Link®, an industry leader in networking, introduces DVG-5121SP VoIP telephone adapter for
the home environment. The DVG-5121SP VoIP Telephone Adapter conver ts any existing analog
(cord or cordless) telephone into an IP Phone. Also by plugging in a FAX machine, the
DVG-5121SP will enable users to send and receive fax the same way as a traditional analog
telephone line.
The DVG-5121SP carries both voice and facsimile over the IP network. It supports SIP industry
standard call control protocol and is compatible with free registration services or VoIP service
providers’ systems. It also supports the most popular audio CODECs to ensure compatibility
and voice quality.
The DVG-5121SP provides two FXS port to connect to two analog telephone sets, PSTN lifeline
port to connect to the phone line, one Fast Ethernet (10/100) port to connect to the VoIP
telephone adapter and another LAN port which allow another computer to be connected by wire.
VoIP service providers can con gure service settings such as a server address, CODEC and
STUN settings via TFTP directly to the DVG-5121SP.
For security, all of the con guration settings are encrypted. Only the VoIP service
providers/resellers with the authenticated password and user name can access them.
The DVG-5121SP features both the VAD (Voice Activity Detection) and CNG (Comfort Noise
Generator) to reduce the band width consumption and to sustain voice quality.
The DVG-5121SPhas a built-in QoS setting to provide voice priority in IP networks and prevent dropped calls.
