Important Safety Instructions When handling or using the VoIP-TA unit, the following safety precautions should be observed to prevent injury and/or damage to the unit. Use of this equipment in a manner other than that specified in this and other VoIP-TA documents will void the product warranty and may result in damage, serious injury or death. WARNING Incorrect use by neglecting the following instructions may cause fire, electric shock, unit failure, resulting in damage, serious injury or death.
• Do not use AC adapters other than those specified or supplied. • If liquid enters the unit, immediately disconnect the power plug (by grasping the power plug, not the cord) from the power outlet and contact an authorized sales agent or service provider. Continued use may result in fire or electric shock. • If smoke or fumes are emitted from the unit, immediately disconnect the AC plug (by grasping the power plug, not the cord).
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.
I 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.

Back Panel Connectors TEL Connects a conventional analogue telephone or G3 facsimile machine. Dial signal: DTMF signaling only. LINE Connects to an analogue public telephone line. PC* Connects to a PC via a straight cable (category 3 or higher). Not for Maintenance Console Software. Use category 5 for 100BASE-TX. LAN* Connects to LAN via a cross cable (category 3 or higher). Use a straight cable for HUB connection. Use category 5 for 100BASE-TX. CONSOLE Connects to a PC (serial port) for data setup.
Table 1 Mode ALARM-LED LINE-LED Status Initialization (1 sec. intervals) Blinks OFF With gatekeeper: The system will wait for LAN link to be established while gatekeeper registers the VoIP-TA. Without gatekeeper: The system will wait for a LAN link to be established. Operation OFF OFF Standby OFF ON The telephone line is busy. OFF Blinks (1 sec. intervals) When using both IP and PSTN: The PSTN is on hold during VoIP calls. When using IP network only: The absent service is setting up.
II 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.
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]. Note It is recommended that only one PC is connected to avoid voice deterioration. 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.
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.
III 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 party’s telephone number.
Services Third party incoming call during another call You can respond to a third party’s incoming call while you are on another call. • A second party telephone call. • If a third party calls, a notification tone is sent to your telephone. • You may speak to a third party by hooking. * The operation varies depending on the data settings.
End-to-end service using DTMF signaling DTMF signaling can be used via the IP network for answering machines, etc. To use this service, Facsimile transmission using the VoIP line, must be turned off. • Making a telephone call Call transfer during a telephone call You can transfer a call during a telephone call. To use this service, Use PSTN line must be turned off.
• Put the other party on hold by hooking, and dial a transfer destination number. • You may then speak to the party at the transfer destination. • When you hang up the handset again the call will be automatically transferred to the destination.
Absent service If the absent service is registered, an incoming call is transferred to a registered destination. The transferred call will not be transferred any further. To use this service, Use PSTN line must be turned off. How to register the absent service Pick up the handset, dial “***11” and the “destination number to be transferred” and hang up the handset. When the service is set, the LINE-LED lamp will blink.
Details of Services There are two ways to use the VoIP-TA unit; using both a PSTN line and the IP network or using only the IP network. These services are determined by the data setup. Using both a PSTN line and the IP network Line selection The selection of a PSTN line or IP network is specified by the first digit of the phone number set by the Maintenance Console Software.
• Incoming operation from the IP network during a telephone call using the IP network. For PSTN line not receiving services using hookflash (hooking) • Response to an incoming call from a PSTN line during a telephone call using the IP network. • Response to an incoming call from the IP network during a telephone call using a PSTN line.
• Incoming operation from the IP network during a telephone call using the IP network. Identification of incoming call An incoming call can be identified by setting a ringing time from IP network and from a public telephone line separately. Example Power failure switching If a power failure occurs, the telephone is directly connected to a PSTN line. CAUTION When supplying power to a telephone set during power failure, the polarity may be reversed depending on a line port connection mode.
Using the IP network only Third party incoming call during another call • Incoming call during an existing telephone call. Translating IP Address for VoIP Without gatekeeper Uses the built-in address table (max. number of registered addresses: 100). With gatekeeper Translates IP address with gatekeeper. Setting IP Address The initial value is not set at the shipment time. Set the IP address using the Maintenance Console Software or obtain it from the DHCP server.
IV Setup The VoIP-TA is set up by using the Maintenance Console Software. The Maintenance Console Software, installed in a PC, is used to communicate with the VoIP-TA in remote mode via a LAN interface or in local mode via a RS232C interface. When connecting to the VoIP-TA using the remote mode via a LAN interface, all network settings such as the assignment of IP addresses must be already completed.
Functions of the Maintenance Console Software The functions of the Maintenance Console Software vary according to the mode in which the VoIP-TA unit has been set. Mode Function Notes Operation mode Perform usual operation. Display the current setup conditions. Setup mode Change the current setup conditions. Change a password. For details on how to change the password, see Chapter V, page 48. Installation mode Update programs of VoIP-TA. Not normally used. See Chapter V, page 47.
