The VoIP Order Wire system from DPS Telecom is an effective way for technicians to communicate
between sites. Sometimes, however, you need to host a "conference call" across multiple VoIP

stations.

You need a simple device that will support this "conference call" functionality without needing to
broadcast packets across your network.

Meet the VoIP Bridge Server

This small device will bridge up to 5 VoIP Order Wire stations into a single conference call. Voice data
from individual stations is sent only to other stations connected to the bridge, rather than being
broadcast across the network. VoIP users simply follow the voice prompt at their station to dial into the
VoIP Bridge Server and join any other connected users on a conference call. Whenever a user enters
or leaves the call, all other connected users will hear an automated announcement.

Before you may use the VoIP Bridge Server to make conference calls with other VoIP Order Wire

stations, you must first assign it an IP address, a subnet mask, and a default gateway. This
provisioning step is performed within the TTY interface.

1. To connect to the VoIP Bridge Server for IP address provisioning, use a physical cable connection
between your PC's COM port and the unit's craft port. Note: You must be connected via craft port
or Telnet to use the TTY interface. Make sure you are using the straight through (1 to 1) Male to
Female DB9-DB9 download cable provided with your VoIP Bridge Server to make a craft port
connection. We'll be using HyperTerminal to connect to the unit in the following example ­however, most terminal-emulating programs should work.

To access HyperTerminal using Windows:

2. Click on the Start menu > select Programs > Accessories > Communications >

HyperTerminal.

8

The following steps are required in order to setup the VoIP Bridge Server and make your first conference call:

1. Set the VoIP Bridge Server's IP Address (using the TTY interface).

2. Add the VoIP Bridge Server to your VoIP Order Wire configuration using the "Orderwire Config"

3. Follow the voice menu prompts on 1 or more VoIP Order Wire stations to connect to the VoIP Bridge

3. At the Connection Description screen, enter a

name for this connection. You may also select an
icon. The name and icon do not affect your ability
to connect to the unit.

4. At the Connect To screen, select Com port

you'll be using from the drop down and click OK.
(COM1 is the most commonly used.)

5. Select the following COM port options:

• Bits per second: 9600

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: None

Once connected, you will see a blank, white

HyperTerminal screen. Press Enter to activate
the configuration menu.

6. When prompted, enter the default user name

admin and password dpstelecom. NOTE: If
you don't receive a prompt for your user name
and password, check the Com port you are
using on your PC and make sure you are using
the cable provided.

Additional cables can be ordered from DPS

Telecom: Part number D-PR-045-10A-04

7. The VoIP Bridge Server's main main menu will

appear. Type C for C)onfig, then E for E)thernet.
Configure the unit's IP address, subnet mask, and
default gateway.

8. ESC to the main menu. When asked if you'd

like to save your changes, type Y for Y)es.
Reboot the VoIP Bridge Server to save its new
configuration.

You have successfully assigned an IP address to the VoIP Bridge Server. This is the only
configuration step required within the VoIP Bridge Serverself. Next, you will need to provision
your VoIP Order Wire devices with the IP address of this VoIP Bridge Server.

NOTE: If you changed your computer's IP earlier in order to connect to the VoIP Bridge Server, be sure
to change the IP of your computer back to one that operates on your network.

15

Add the Bridge Server to your Order Wire Configuration8.2

To simplify the process of dialing into a conference call, VoIP Bridge Servers must be pre-databased in the
configuration of any VoIP Order Wire station that will connect to that VoIP Bridge Server (in most cases, all stations
will be updated). This process allows fast 2-digit dialing to reach a Bridge Server, rather than the cumbersome
process of dialing a full IP address with a phone keypad.

NOTE: These instructions describe only the configuration of the "Conference Servers" tab. The other tabs,
especially "Directory", must also be configured as part of a new VoIP deployment. If no Order Wire stations have
been listed in the "Directory" tab, the "Write to all devices" step at the end of this section will have no effect. Refer
to the Help file contained within Orderwire Config for information about configuring the other software tabs.

1. To add Bridge Servers into your Order Wire station configuration, launch the "Orderwire Config" application
that was packaged with your VoIP Order Wire stations. If you do not have this software, it is available as a free
download at: http://www.dpstele.com/mydps/

2. Next, you must add a new entry in the "Conference Servers" tab for your new VoIP Bridge Server. If your
version of the Orderwire Config software does not have this tab, you should download the latest version at http://

www.dpstele.com/mydps/

As shown in the example below, enter the following information for your VoIP Bridge Server:

A two-digit "Conf. Id" number (01-08). This number will be dialed from a VoIP Order Wire station to reach the
Bridge Server.

The "IP" address of the Bridge Server that you defined earlier.
A "Description" that will serve as a helpful reminder for you. In the example below, the Description field has

been used to store the purpose and location of the Bridge Server.

16

If you have additional Bridge Servers, you may use the other rows to configure them as well. Up to 8 Bridge Servers
may be defined in a single Order Wire configuration.

3. Once you are satisfied with your configuration update, you must write the configuration to your VoIP Order
Wire stations for it to take effect. The simplest method is to click "Connect" >> "Write to all devices". This will write

the configuration to all devices defined in the "Directory" tab of Orderwire Config.

Your Bridge Server configuration has now been saved to your Order Wire stations (as listed in the
"Directory" tab). You are now ready to make your first conference call, as described in the next section.

Dial into the Bridge Server from Order Wire stations8.3

After giving your Bridge Server an IP address and adding it to the configuration of your Order Wire stations,
you're now ready to make your first conference call using the Bridge Server.

1. Pick up the handset of a VoIP Order Wire station.

2. Dial '3' to "join a conference." (Pressing '#' instead will list the various menu options, including "To join a

conference, press '3'". Experienced conference users, however, will simply press '3' directly after picking up the
handset). After dialing '3', you will be prompted to "Enter 2-digit conference ID."

3. Dial the 2-digit "Conf. Id" (01-08) of your desired Bridge Server. You defined this in the Order Wire

configuration during the previous setup section.

You will now be connected to the conference, but you will be the only person on the call. If you wish, you
may dial into the call from another Order Wire station (use the same 3 steps above) to test the conference call
functionality.

Users on a conference call will hear an automatic verbal announcement when a user enters or leaves the
conference call. The joining user will also hear the verbal announcement of his/her own entry into the room.

NOTE: A single VoIP Bridge Server will support up to 5 simultaneous users. Any user who attempts to join

a conference call that is already full will hear an error prompt.

If you have a question about the VoIP Bridge Server, please call DPS Telecom at [phone] or e-
mail us at [email protected]

Frequently Asked Questions

General FAQs10.1

Q. How do I telnet to the VoIP Bridge Server?
A. You must use Port 2002 to connect to the VoIP Bridge Server. Configure your Telnet client to

connect using TCP/IP (not "Telnet," or any other port options). For connection information, enter the
IP address of the VoIP Bridge Server and Port 2002. For example, to connect to the VoIP Bridge
Server using the standard Windows Telnet client, click Start, click Run, and type "telnet <VoIP
Bridge Server IP address> 2002."

Q. How do I connect my VoIP Bridge Server to the LAN?
A. Remember that the only purpose of the VoIP Bridge Server's web interface is to update firmware.

To connect your VoIP Bridge Server to your LAN, you need to configure the unit IP address, the
subnet mask, and the default gateway via the TTY interface (using Telnet). A sample configuration
could look like this:

Unit Address: 192.168.1.100
subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1

Save your changes by writing to NVRAM and reboot. Any change to the unit's IP configuration
requires a reboot.

Q. When I connect to the VoIP Bridge Server through the craft port on the front panel it either

doesn't work right or it doesn't work at all. What's going on?

A. Make sure your using the right COM port settings. Your COM port settings should read:

Bits per second: 9600 (9600 baud)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Important! Flow control must be set to none. Flow control normally defaults to hardware in most

terminal programs, and this will not work correctly with the VoIP Bridge Server.

Q. I'm unsure if the voltage of my power supply is within the specified range. How to I test the

voltage?

A. Connect the black common lead of a voltmeter to the ground terminal of the battery. Connect the

red lead of the voltmeter to the battery's VDC terminal. The voltmeter should read a value that is
within the range listed in the "Specifications" section of this manual. The acceptable voltage range is
also commonly listed on the back panel of the unit near the power connector.
