solution for corporations and individuals. IP870 allows various connection modes such as
IP870-to-IP870, IP870-to-IPStar, IP870-to-InterStar, IP870-to-InterPhone and IP870-to­Phone via Internet or other TCP/IP networks.

You start saving big budgets by owning an IP870 today! Better yet, thanks to DSG's
JustDialIt technology, your receiver end does not need another IP870 to enjoy this
advanced VoIP technology. Your long-distance and international call charges will
disappear with this extraordinary device. It is the first Ethernet phone device that offers
full duplex, supreme quality and low latency voice conversation via Internet/Intranet at
extra-low charges.

Understanding Your IP870 1-1

A Brief Overview

1-2 IP870 Operation Manual

In the past, real-time voice information is sent over the Public Switched Telephone
Network (PSTN). With the Circuit-switched technology, every call takes up a dedicated
bandwidth. End-to-end calls are established on the basis of a sequence of dialed 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 a PSTN, an Internet Protocol (IP) network has a packet-switched
architecture. Devices transmit data in packets, and the path from end to end can vary
within an established session. In addition to data, packets also contain addressing
information, which routing devices used to send information to its destination. Routing
devices maintain tables which instruct them how to direct packets. As networking

environments change, routing devices are updated with dynamic protocols.

A Brief Overview

Traditionally, the PSTN was the only network supporting voice communication. With an
IP870, voice traffic can be sent over IP-based packet-switched networks!

IP870 possesses its own processor and network interface; it works intelligently! Simply
enter the Internet access information into your IP870, then you are ready to talk as long as
you wish via Internet. All of the communication cost will be eliminated except a local

Internet connection charge.

No Computer Needed

With a back-lit LCD display and five buttons, IP870 is extremely easy to use and to
configure. Smart setup program makes your IP870 ready to go in three minutes. You can

clearly monitor all the system status from the LCD panel.

Appendix B. Troubleshooting

Appendix B. Troubleshooting

You attempted to make an IP870-to-IP870 call but it didn't work.

Use our quick start guide, check that both IP870s are configured properly. During the
process of making an IP870-to-IP870 call, you can check for an online symbol "@" on
the LCD screen of your IP870 to confirm your status. When one of the IP870 users dials
to the receiving IP870, you can clearly monitor the connecting process on the LCD
screen. If you have made several attempts by device ID and have failed, then try using
the IP Phone Book option with user-defined codes! (Refer to Chapter 4 How To Use
Your IP Phone Book).

Problems Making an IP870-to-IP870 Call

No clue on finding your IP870's six-digit ID.

Every IP870 has a unique six-digit device ID number and it can be found at the bottom of
your IP870 device. You can also find this six-digit ID number in the configuration mode
SYSTEM SETUP/DEVICE ID. If you are still having trouble finding this ID number,
please refer to Chapter 3 for more information.

You entered the IP870's six-digit ID and the screen showed "Ready for Dial".

You probably left out a leading * key before the six-digit ID number. For example, if you
want to make an IP870-to-IP870 call to a friend with an IP870 ID 001234, enter
*001234# in the 'Ready to Dial' mode to complete your call.

You entered your receiving IP870's six-digit ID number and the screen showed

"Party Off Line".

Before you make an IP870-to-IP870 call, check to see that you have entered the correct
six-digit ID number of the receiving IP870. At the same time, you may check to see if the
remote IP870 you wish to connect is online by simply entering the IP Address. If your
receiving party is not online, then you can try again later.

Appendix B. Troubleshooting

You entered the designated phone number and the screen showed "Ready for Dial".

You should check if the ITSP account number is entered correctly. If you need further
information on ITSP account, please refer to Chapter 6 for help.

Problems Making an IP870-to-Phone Call

You entered the designated phone number and the screen showed "No Service".

It is important that you input the correct country code, long-distance code, and
international code when making an IP870-to-Phone call since your IP870 uses these
information to analyze the phone number you dialed. Another possible reason for "No
Service" could be that the number you dialed is out of the service area. To obtain the
detailed information on all the available countries, please refer to our web site
www.dsgtechnology.com.

You entered the designated phone number and the screen showed "Wrong
Account".

When the screen shows "Wrong Account", it's either you have entered an invalid ITSP
account, or there is no balance remaining in your ITSP account. To renew, update, or re­activate your ITSP account, contact your local distributor or visit our web site at
www.dsgtechnology.com.

You entered the designated phone number and the screen showed "Server Busy".

When the screen shows "Server Busy", it means that all lines are busy and temporarily
unavailable. You can try calling later.

Problems during an Internet Call

Appendix B. Troubleshooting

During the call, you experienced a slight delay in your conversation.

This is an expected Internet phone situation. The degree of voice delay depends on the
Internet traffic and the routing path. IP870's Dynamic Jitter Buffer Control algorithm will
optimize the delay time automatically in the first ten seconds of your call.

During your call, you have difficulty hearing the other party.

On your IP870's LCD screen, you will see the network percentage indicator to identify if
the Internet traffic is congested. You can wait to see if the traffic subsides indicated by
the percentages or press the button to end your call or try calling later.

During the call, the other party's voice seems slow or delays seriously (more than
three seconds).

It is a matter of the bandwidth between your IP870 and the ISP. It could be that the
bandwidth is not enough to support a regular Internet call. At this point, you may end
your call and place another call to see if the voice quality improves. If the voice quality
remains unsteady, then set the Voice Delay in the Configuration Mode to High and try
calling again.

If there are still other problems other than the ones stated above.

We recommend that you use other ISPs to ensure the best Internet connection quality.
