Introduction  
Welcome to the world of Oki Internet telephony…  
The Oki voice over IP (Internet Protocol) telephony adapter, VoIP-TA, is a  
self-contained H.323 version 2 compliant communications device that  
allows organizations to route both voice and facsimile communications  
over any TCP/IP network.  
The VoIP-TA is designed to provide a service that is virtually  
indistinguishable from that of conventional telephone and facsimile  
services.  
Use this guide to familiarize yourself with the VoIP-TA. Should you need  
to handle the equipment, pay special attention to the procedures and  
safety precautions contained in this guide.

Introduction

Outline  
The VoIP-TA  
The VoIP-TA is a one-channel Internet telephony adapter that provides  
Internet telephony services conforming to industry standard H.323  
version 2 specifications. It can be connected to a conventional analogue  
telephone or G3 facsimile machine.  
Once installed, VoIP-TA units use the Internet Protocol (IP) network to  
bridge the distance between units at a fraction of the cost associated with  
conventional telephony methods.  
* Gatekeeper is necessary when more than 100 IP addresses are to  
be used.  
Features  
Compact size and one-channel Internet telephony adapter.  
Automatic telephone routing by specified telephone numbers.  
Smooth and natural telephone calls by optimizing the voice buffer.  
Supports Dynamic Host Configuration Protocol (DHCP manual  
allocation) for local IP addresses.  
Conforms to the ITU-T recommended H.323 version 2 specifications.  
Supplies real-time Internet facsimile communication.  
Uses high quality voice compression technology.  
The Public Switched Telephone Network (PSTN) is supported by VoIP-TA version  
1.2 and later. The version number is clearly marked on the bottom of the unit. Please  
contact your network manager or authorized sales agent or service office if in doubt,  
to avoid incorrect use.

PC port during a call, the call may be interrupted for approximately one second.  
Please avoid such usage.

Installation  
Place the main unit in a vertical position as placing it horizontally could  
shorten the life of the unit.  
Connections  
The following illustration shows where equipment should be connected  
to the ports at the rear of the VoIP-TA unit.  
Analogue telephone or G3 facsimile equipment  
Connect an analogue telephone or G3 facsimile machine to the TEL  
connector of the VoIP-TA unit via a telephone cord.  
To make facsimile connections, the other end terminal equipment should  
be compliant with the ITU-T T.38 standard.  
Analogue PSTN  
Connect an analogue PSTN line to the LINE port at the rear of the VoIP-TA  
unit via a telephone cord.

Installation  
5
Personal computer (PC)  
Connect a PC connector to the PC port at the back of the VoIP-TA unit  
using an unshielded twisted pair (UTP) straight cable (categories 3 to 5).  
If both a PC and LAN are to use 100BASE-TX communications, use  
category 5 [max. 100m].  
It is recommended that only one PC is connected to avoid voice deterioration.  
Note  
LAN  
Connect the LAN connector to the LAN port at the back of the  
VoIP-TA unit via a cross cable (UTP categories 3 to 5). If connecting to a  
hub, use a straight cable.  
If the LAN is connected by 100BASE-TX and the PC is connected by  
100BASE-TX, or if the PC is not connected, use a category 5 cable  
[max. 100 m].  
CONSOLE (setting up the VoIP-TA with a PC)  
Connect the PC for setup on the VoIP-TA by using the serial cable RS-  
232C (9 pin – 9 pin straight) to the CONSOLE port.  
FG (grounding)  
After connecting the frame ground (FG) cable to the FG port at the back  
of the VoIP-TA unit, connect the other end to a ground terminal in the  
house or ground it separately.  
Power source  
Connect the supplied AC adapter to the DC IN 12V port at the back of the  
VoIP-TA unit. Connect the attached AC adapter to a power outlet.

Installation  
6
Cautions  
During installation  
All cables used to connect the equipment must be accessories of the  
equipment or suitable to fit the equipment.  
Make sure the AC power plug is disconnected from the power outlet  
when connecting the FG cable to the unit.  
When an exchange machine, such as PBX or EKTS is connected to the  
TEL port of VoIP-TA, the sound quality may deteriorate. Only one  
exchange machine should therefore be relayed between the VoIP-TA unit  
and telephones.  
Interference noise may occur during telephone calls in areas that receive  
strong radio waves, such as near a broadcasting station or CB radio  
transmission. If calls are affected in this way, consult your network  
manager, an authorized sales agent or service office.  
Do not install the VoIP-TA unit near equipment that generates  
magnetism or radio waves such as TV sets, radios, radio machines,  
microwave ovens, or inverter-type fluorescent lamps, as this may cause  
the unit to malfunction.  
During use  
Do not subject the unit to strong impact, such as dropping the unit.  
Do not force cables to connect or disconnect as this may result in faults.  
The connector and port should join with reasonable ease.  
When cleaning the exterior of the VoIP-TA, turn it off and disconnect the  
unit (by pulling the power plug, not the cord), wipe it with a water damp  
cloth and wipe it dry with a soft dry cloth. Do not use volatile thinner,  
alcohol or a silicon cleaner under any circumstances as it may result in  
damage, discoloration or deformation.

Placing Calls  
Via an IP network  
Placing and receiving calls with the VoIP-TA unit are usually quite simple  
and performed in the same way as conventional telephone networks. In  
some cases however, the phone numbers to be used, may differ slightly  
from the ones you used previously.  
General operation  
Outgoing calls  
Use a telephone that generates a Dual Tone Multiple Frequency (DTMF)  
signal. Pick up the handset and dial a remote partys telephone number.  
Incoming call response  
An incoming tone will be emitted from the telephone.  
Disconnection  
A telephone call can be disconnected by hanging up the handset onto the  
telephone receiver.
