1-1Understanding Your InterPhone

InterPhone Operation Manual

n Overview

In the past, real-time voice communication is sent over the Public Switched Telephone Network
(PSTN). With the circuit switched technology , every call takes up a dedicated bandwidth. End­to-end calls are established on the basis of a sequence of dialled digits, and the PSTN dedi­cates a physical path between callers. Although the telephone equipment establishes the call
path at the beginning of the call, the path may change between calls, but not during any specific
call.

In comparison with the PSTN, an Internet Protocol (IP) network has a packet-switched
architecture. Data are transmitted in packets, and the path from end to end can vary within an
established session. The data packets also contain the destination IP address information,
with which packets are routed. As networking environments change, routing devices are up­dated with dynamic protocols.

InterPhone is a complete Ethernet telephone set, which transmits voice traffic over IP-based
packet switched networks, and it is able to use as a traditional PSTN telephone.

All-in-one Design

InterPhone has its own processor and network interface; it works independently and intelligently!
Simply dial the IP address or device ID of the remote party from your InterPhone, then you are
ready to talk via the Internet. All of the communication costs will be eliminated except a local
Internet connection charge. InterPhone is the most convenient Ethernet phone for users to
make Internet phone calls remaining the same habit as they make IDD (International Direct
Dialling) calls.

InterPhone is an amazing electronic device. In addition to InterPhone-to-InterPhone, InterPhone­to-IPStar and InterPhone-to-InterStar modes, the unparalleled InterPhone-to-Phone and Phone­to-InterPhone modes greatly enhance the capability of voice communication by using the Internet
or TCP/IP networks. InterPhone users can save significantly on long-distance and international
call charges with these features.

InterPhone-to-InterPhone Mode

If the party you wish to call is equipped with an InterPhone, you may enter the Device ID Num­ber with button prefix or IP address directly and talk to the remote InterPhone owner
instantly. Or you may use IP Phone Book to call the receiving party with user-defined speed
dial buttons.

InterPhone-to-IPStar/InterStar Mode

Every DSG’s VoIP client device has a unique ID number. Make sure that your receiving
InterStar/IPStar user is already online, then simply dial the ID number with button prefix or IP
address, if it is available, of the receiving device and you will be automatically connected. Thus
all your connection charges can be saved!

Note: IPStar is a Modem-based Internet phone device. InterStar is an Ethernet phone device.

1-4

InterPhone-to-Phone Mode

With great interoperability, InterPhone is capable of connecting to PSTN, regular telephone
system, by transferring through other Internet Telephony products, such as DSG IP1000 and
IP2000 Gateway . With an active ITSP (Internet Telephony Service Provider)
Account or Device ID Number, you can call all the covered areas with ultra low rates. In this
mode, the receiver end does not need any InterPhone or V oIP device.

Note: IP1000, IP2000 are DSG VoIP Gateways connecting the Internet and PSTN (Public
Switched Telephone Network). A V oIP Gateway enables callers using Internet to talk to regu­lar phone users without traditional telecommunication services.

Phone-to-InterPhone Mode

For regular phone users, you can also enjoy the savings! To call an InterPhone user, first you
dial to a local DSG IP2000 Internet Gateway . Once you are connected, simply dial the six-digit
Device ID Number with button prefix and you can talk to any worldwide InterPhone users!

Note: To use InterPhone-to-Phone Mode or Phone-to-InterPhone Mode, callers must sub­scribe the services provided by DSG Internet Telephony Network from DSG compatible ITSPs.

Free Online Upgrade

The design of InterPhone is extremely flexible. New selections and options will be added into
your InterPhone via the online upgrade function. Y ou are guaranteed to enjoy the latest Internet
Telephony technologies at no cost.

Appendix A : Troubleshooting the InterPhone

1. How do I know if my configuration is successful?

After you complete Basic Setup, on the LCD panel you will see a steady sign on PSTN Mode
or a steady @ sign on I-PHONE Mode.

2. If my sign (on PSTN Mode) or @ sign (on I-PHONE Mode) is not steady,ie,flashing,
what should I do ?

Check the Basic Setup Items: IP Address, Gateway IP Address, Subnet Mask. Y ou may get
the above information from your ISP or MIS personnel.

3. Do I need a real IP address to configure my InterPhone?

Y es! You need to assign a real IP address to your InterPhone. Moreover, this IP address
cannot be shared by other equipment on the LAN.

4. If my ISP assigns a dynamic real IP to me, what I should do?

Some broadband operators assign dynamic IP addresses to subscribers. InterPhone supports
DHCP function. Make sure the dynamic IP is real IP. Go to DHCP setup item and enable this
function.

5. If there is a DHCP on the LAN, what I should do?

InterPhone supports DHCP function. If there is a DHCP server on your network environment,
simply go to DHCP setup item and enable this function.

6. What kind of network interface does my InterPhone support?

InterPhone provides value added voice communications for broadband or wideband users. It
supports Ethernet interface from Leased Line, xDSL and Cable Modem.

7. There is a firewall on my LAN. Will it block my voice?

If there is a firewall on your LAN, it blocks the voice packets, too. At this moment, the remote
party can hear your voice but the remote party’s voice will be blocked by the firewall. Please
advise your MIS personnel to open UDP 1 101 port and TCP 1 100 port so that the voice data
can pass through.

8. If I have a PBX in my office, can I share the InterPhone so that everyone can use it?

The home version of InterPhone is designed for individual users. We don’t recommend you
equip home version of InterPhone on your PBX system. The impedance might cause noises.
We recommend you to use the other DSG Ethernet Phone Device “InterStar” for PBX
application.

9. Can I upgrade my InterPhone?

Y es! DSG T echnology keeps on providing more functions to users. To download the latest version,
simply go to SYSTEM SETUP and enter AUTO UPGRADE item. Press ENETR button. InterPhone will
download the latest software for you automatically.

and from any regular PSTN telephone. After you apply the services from DSG ITSP
distributors, you will be given calling points. With valid calling points in your InterPhone, you
can make Internet phone calls to any regular telephone users.

Check the following setup items are correct: Long Distance Code, International Access Code,
Country Code and ITSP Account (if any).

7. On I-PHONE Mode, why can’t my call be transferred directly to an extension?

On I-PHONE Mode, due to the hardware limitation, InterPhone cannot send DTMF signals.
Therefore you may have to require the operator to transfer your call to an extension side.

8. Why does it sometimes take so long to connect to the remore party?

The Internet quality affects the quality and connection speed of Internet phone calls. Check
your Internet condition. Y ou may judge it by the time it takes to get your account balance
report, server found message, and network % shown on the LCD panel. Y our DNS setting
may also affects your time of finding servers and remote parties.
