Part One: An Introduction to VoIP
Summary: What Is Voice Over Internet Protocol?
Voice over internet protocol (VoIP) is a communications technology that uses the internet to transfer voice signals in the form of bits and bytes. It delivers these bits and bytes to a specified internet address rather than a telephone number. It’s easier to think of it as being like sending e-mail from one computer to another, but in real time and using voice instead of text. The technology that most likely runs your existing switchboard and phones is a traditional public switched telephone network (PSTN) service. VoIP’s advantage over this is its ability to combine several services, such as voice mail, video, e-mail and conferencing. This instantly increases your ability to collaborate and can result in higher productivity.

Installation

The following instructions will guide you to through the process of installing the Personal USB Gateway.

STEP 2: Insert the supplied CD-ROM into your PC CD-ROM drive. The installation should start automatically. If not, open the installation folder on the CD-ROM and double click on the setup.exe program as shown below.

The other end of the USB cable must be connected to a USB port on your computer or to an AC Powered USB hub.

STEP 3: You would then see following screen if your Skype is already running. If not, start your Skype program. Refer to STEP 1 for how to download the Skype program.

What is the 3CX VOIP client?

The 3CX VOIP Client is a small Windows application that allows you to make and receive calls via your desktop phone or using a headset connected directly to your computer.

You can see the extension numbers of other users and whether they are available to take calls. Important is that you can use the 3CX VOIP client without having to use the head-set – you can continue to use your desk based phone if you prefer.

The 3CX VOIP client ships with all editions of 3CX Phone System, including the Free edition. However, in the Small Business, Pro and Enterprise editions, the 3CX VOIP client allows you to see the presence of other users on the phone system. In the FREE edition, other extensions appear greyed out.

Installing 3CX VOIP client

Step 1. Preparation

1. Prepare the site before beginning the installation. See Chapter 2, “Site Preparation” in the
   MIP 5000 VoIP Radio Console Installation and Configuration Manual.
   Important: Make sure there is a network access port in each location where a MIP 5000 Gateway is to be installed. An additional port is recommended for use by service personnel.
2. If required, install the electronics equipment shelves intended to hold the MIP 5000 Gateway units.
3. Consult with the network administrator to determine whether the network uses static or dynamic IP addressing.
• If static, IP addresses are used to identify gateways and consoles.
• If dynamic, Host Names are used to identify gateways and consoles.
4. Collect the MAC address of each MIP 5000 Gateway to be installed. Use a photocopy of the
   Discovery Form on the back of this guide to make a list that identifies which MIP 5000 Gateway is for which radio channel and what the MAC address is.
• The MAC address (physical address) of each MIP 5000 Gateway appears on a label on the bottom of the unit.
5. Collect a Host Name (dynamic) or IP address (static) for each gateway.
   Note: Each gateway has a default Host Name set equal to its MAC address: 12 hexadecimal digits (without hyphens). You do not need to set gateway Host Names, unless you want to change their default values.
• If static addressing is used, get IP addresses for the gateways from the system administrator.
• Write the Host Name or IP address for each gateway on the Discovery Form.
6. On the Discovery Form, write the MAC address (Physical Address) and Host Name or IP address of each computer on which the MIP 5000 console program is to be installed.
• Click Start > Run, type “command” and click OK.
• In the Command Prompt window, type “ipconfig /all” and press ENTER.
• Write the Physical Address (MAC address) and Host Name or IP address on the Discovery Form.
• (If there is more than one Physical Address, use the one for the “Local Area Connection” or consult with the network administrator.)
• The network administrator should be responsible for implementing the assigned IP address or Host Name on each console computer.

Note: If the console computers are already in service on the network, they already have a Host Name or fixed IP address. In this case, no further action is required to implement the assignment of Host Names or IP addresses.

7. If your network uses dynamic addressing, have the network administrator reserve IP addresses in the DHCP server for all gateways and consoles using the MAC addresses on the Discovery Form.

Step 2. Administration Software Installation

1. Consult with the network administrator to get the user name and password for a network account with administrator rights for use while installing software on the CSDM and dispatcher computers.
2. Install the CSDM program on a computer in the network. This computer can also serve as a console, but must be able to run 24 hours a day, 7 days a week.
• Insert the CD-ROM, select Install CSDM.
• Depending on Windows security settings, security warnings may appear. Click Yes or Run, as appropriate to continue installation, then follow the installation wizard.
• Record Host Name or IP address of CSDM computer to enter as TFTP Server address during console installation.
3. Install the Secure Shell (SSH) program included on the MIP 5000 installation CD-ROM.
• Select Install SSH.
• Depending on Windows security settings, security warnings may appear. Click Yes or Run, as appropriate to continue installation, then follow the installation wizard.

Note: We recommend that you install the SSH program on the same computer as the CSDM program.

Prepare

Before you start. Please ensure that you have at least one computer with a spare USB 2.0 port. Below is a list of software and requirements you should also prepare:
At least one application that enables you to speak over the internet for free.

Connections

Unpack the USB VoIP Dialpad, connect the USB cable to your computer and to the rear of the USB VoIP Dialpad. Now power on your computer. With Windows 2000 and Windows XP, the Drivers will automatically be located and installed. The keypad will light up once the Dialpad is configured correctly.

2 sets of switchable connectors have been provided, one for the supplied headset, the other for desktop speakers and mic; both are interchangeable. Speaker connector is green, Mic connector is pink. The Audio A-B switch simply switches audio in and out to A or B connector, great for switching between private
conversation or conference.
