Introduction

The DPH-400S(SE) IP Phone is an Internet Telephony desktop phone that connects to a digital network rather than the traditional PSTN line.
Basically, it needs to be connected to a LAN enterprise network and works as an office phone. Like a traditional office telephone, it can deliver good
voice quality and perform a great number of PBX-equivalent call features.
The IP phone can transfer and receive voice via an IP network. Therefore, it can be deployed and connected all over the world among headquarter
and remote branch offices. Since it is a stand-alone and "always-on" terminal, there is no need to have any active PC to make it work. The IP Phone
is completely stand-alone.
The IP phone comes with a graphic LCD screen, traditional keypad, a navigator key & content-sensitive programmable keys, handset, I/O ports,
and a power adapter. It can be installed and placed on a desktop or mounted on the wall.
