VoiceCenter™ IP Phone

What is VoiceCenter™?

D-Link® VoiceCenter™, a Microsoft® Response Point™
phone system, is an IP-based phone system designed for
small to medium-sized businesses (SMB) with support
for up to 50 users. VoiceCenter provides numerous
advantages over traditional PSTN (analog) phone
systems while retaining the reliability of PSTN phone
lines1 for accepting inbound and making outbound calls.
Unlike previous generations of complicated, hard-to-use
IP-based products, VoiceCenter is easy to install, manage,
and maintain. Rather than taking days, it only takes a short
amount of time to get the phone system up and running.
VoiceCenter is also portable - businesses that need to
relocate offices can easily take the phone system along.
In addition, while D-Link provides solid phone system
hardware, the integrated Microsoft Response Point
phone system software provides state-of-the-art features
such as Voice-activated Dialing and Voicemail Access,
Automated Attendant for routing calls, and Automatic
Phone and Gateway Discovery that allows for a simplified
setup process.

Add More Phones As You Go

The VoiceCenter phone system is a scalable solution that
supports up to 50 DPH-125MS IP Phones on a network.
There are no fees or licenses required for adding more
phones to the system. Thus, as your company grows and
hires new employees, you only need to purchase more
DPH-125MS IP Phones.

Easy To Install And Use

Because the entire VoiceCenter phone system is designed
with simplicity in mind, you can set up a phone and user
from start to finish in minutes. To minimize time and hassle
with Ethernet cabling, the IP Phone provides a pass-through
Ethernet port for connecting another device such as a
computer to a network. Once the hardware connection is
made, you can use the Phone Setup Wizard provided by the
Microsoft Response Point software to assign extensions
and names that only takes a couple of steps.

The D-Link DPH-125MS IP Phone provides advanced
and standard telephony features as part of VoiceCenter,
a Microsoft Response Point phone system. With a solid,
dependable hardware platform from D-Link and an easy
to use, install, and manage phone system software from
Microsoft, the VoiceCenter phone system is the clear
choice for today’s productivity and efficiency-minded small
to medium-sized business.

State-of-the-Art Features

The DPH-125MS IP Phone includes many standard and
advanced features not found in analog phone systems. With
the built-in Microsoft Response Point (RP) button, users have
one-touch access to Voice-activated commands. Voice­activated Dialing is one of the Voice-activated commands
that enable users to reach anyone in the company directory
or their Microsoft Outlook address book by simply saying
their name. Users can also transfer, park, and retrieve calls
the same way. Voicemail to E-mail Forwarding is another
convenient feature. With the Call History function, users can
easily view the calls that were received as well as the calls
that went out. In addition, standard features such as Mute,
Hold, Transfer, Speakerphone, and 3-Way Conference
functions are included.
