Administration for Network Connectivity

1 Networking Overview
IP Softphones
This book focuses on administration for the trunk side of the DEFINITY IP Solutions offer. The administration
of the line side (IP Softphones) is covered in DEFINITY ECS R8 Administrator’s Guide, 555-233-506. For
completeness, a brief checklist of IP Softphone administration is presented here.
For R8, there are two main types of DEFINITY IP Softphone applications — the
telecommuter application and the road-warrior application. The CentreVu IP Agent is
a variation of the telecommuter application.
Telecommuter
application
The telecommuter application uses two connections to the DEFINITY system: a
connection to the PC over the IP network and a connection to the telephone over the
PSTN. The user places and receives calls with the DEFINITY IP Softphone interface
running on a PC and uses the telephone handset to speak and listen.
To administer a telecommuter application, you must complete these steps:
1 Verify that the DEFINITY system is enabled for IP Softphone use. On the System
Parameters Customer Options screen, verify that:
~ Maximum H.323 Stations is > 0
~ Maximum IP Softphones is > 0
~ IP Stations is y
2 Add a DCP station (or change an existing DCP station) using the Station screen:
~ Type [enter the phone model you wish to use, such as 6408D]
~ Port: x if virtual, or the port number of an existing phone
~ Security Code: [enter the user’s password]
~ IP Softphone: y
~ Go to page 2; Service Link Mode: as-needed
3 Install the IP Softphone software on the user’s PC
Road-warrior
application
The road-warrior application uses two separate software applications running on a PC
that is connected to a DEFINITY system over an IP network. The single network
connection carries two channels: one for call control signaling and one for voice.
DEFINITY IP Softphone software handles the call signaling and an H.323
V2-compliant audio application (such as Microsoft
NetMeeting
) handles the voice
communications.
To administer a road-warrior application, you must complete these steps:
1 Verify that the DEFINITY system is enabled for IP Softphone use. On the System
Parameters Customer Options screen, verify that:
~ Maximum H.323 Stations is > 0
~ Maximum IP Softphones is > 0
~ IP Stations is y
2 On the DEFINITY system, add an H.323 station using the Station screen:
~ Type H.322
~ Port: x
