							3 This guide describes how to install the DEFINITY
® IP Softphone applications 
and log into the DEFINITY server. DEFINITY IP Softphone is a collection of 
computer telephony integration (CTI) applications that enables you to control 
telephone calls (both incoming and outgoing) directly from your PC. 
DEFINITY IP Softphone enables you to log into your company’s DEFINITY 
server remotely and make and receive telephone calls from the telephone 
extension.

							4 DEFINITY IP Softphone supports the following three configurations:

Road-Warrior Configuration (Voice over IP)
The road-warrior configuration enables travelers to use the full 
DEFINITY ECS feature set from temporary remote locations anywhere 
in the world (such as a hotel room). The road-warrior configuration 
consists of two software applications running on a PC that is 
connected to DEFINITY ECS over an IP network. The single network 
connection between the PC and DEFINITY ECS carries two channels, 
one for the signaling path and one for the voice path. DEFINITY IP 
Softphone software handles the call signaling and an H.323 V2-
compliant audio application, such as Microsoft
® NetMeeting® 3.0x, 
handles the voice communications. The user places and receives calls 
via the IP Softphone interface on the PC and uses a headset 
connected to the PC (or the PC’s microphone and speakers) to speak 
and listen.
With the road-warrior configuration, Microsoft NetMeeting has been 
configured to run in the background and uses only the audio portion of 
the application. The data collaboration feature of NetMeeting can be 
used as a stand-alone application, but it is disabled during an IP 
Softphone session.

							5 You can use an H.323 application other than Microsoft NetMeeting 
3.0x in the road-warrior configuration. However, if you use an H.323 
application other than Microsoft NetMeeting 3.0x, that H.323 
application will not run in the background like Microsoft NetMeeting.
NOTE:
DEFINITY IP Softphone works with any H.323 Version 2-compliant application 
(such as Microsoft NetMeeting 3.0x) that can register with an E.164 alias.

Telecommuter Configuration (Dual Connection)
The telecommuter configuration of DEFINITY IP Softphone enables 
telecommuters to use the full DEFINITY ECS feature set from home. It 
consists of a PC and a telephone with separate connections to 
DEFINITY ECS. The PC is connected to DEFINITY ECS over an IP 
network to provide the signaling path. The PC runs the DEFINITY IP 
Softphone software to provide the user interface for call control. A 
standard telephone is connected to DEFINITY ECS over the public-
switched telephone network (PSTN) to provide a high-quality voice 
path. The user places and receives calls via the IP Softphone interface 
on the PC and uses the telephone handset to speak and listen.
When you make or answer a call with DEFINITY IP Softphone, your 
separate telephone line is controlled by the DEFINITY server. While 
the DEFINITY server controls this telephone line, you are unable to 
place calls from the telephone attached to this telephone line. Any 
digits you dial from this telephone will be dialed during the current call. 
When the DEFINITY server no longer controls the telephone line, you 
can place calls from the telephone attached to the telephone line. 
If you receive an incoming call on your separate telephone line while 
that line is controlled by the DEFINITY server, that caller will hear 
either ringing (if you have call waiting on that line) or a busy signal. If 
you have call waiting, you can answer the incoming call as you would 
answer any other call waiting call. 
For the telecommuter configuration, you must have a separate 
telephone line available at your remote location. You do not need an 
H.323 PC audio application such as Microsoft NetMeeting 3.0x.

Stand-alone H.323 Configuration (Voice over IP)
The stand-alone H.323 configuration enables users to place and 
receive calls via an H.323 V2-compliant audio application, such as 
Microsoft NetMeeting 3.0x, running on a PC that is connected to 
DEFINITY ECS over an IP network. Since this configuration offers 
limited call handling capabilities, the stand-alone H.323 configuration is 
not recommended.

If you will always have a separate telephone line for a voice 
connection (telecommuter configuration), make sure you have 
the following:

a valid user account on your company’s LAN

a valid user account on your company’s DEFINITY server. (Verify your 
account administration with your DEFINITY System Administrator. Your 
DEFINITY System Administrator will provide you with an extension 
number and password for your account.)

the node name or IP address for the DEFINITY server (that is, the IP 
address for the C-LAN)

the telephone number to access your company’s LAN via dialup 
networking (if you are logging in via a modem)
Now, verify the hardware and software requirements for DEFINITY IP 
Softphone (page 24), and then go to “Step 1: Install the DEFINITY IP 
Softphone Software” on page 13.
