Chapter 2 Preparing to Deploy Cisco IP Communicator

Installation Prerequisites

2-2

Cisco IP Communicator Administration Guide for Cisco CallManager

OL-4698-01

Installation Prerequisites

Before deploying the Cisco IP Communicator application to users, read the

requirements in these sections:

• Network Requirements, page 2-2

• Cisco CallManager Configuration Requirements, page 2-3

• Client PC Requirements, page 2-3

Network Requirements

For Cisco IP Communicator to successfully operate as an endpoint in your

network, your network must meet the following requirements:

• Voice over IP (VoIP) configured on your Cisco routers and gateways

• Cisco CallManager Release 3.3(3) SR 3 or higher installed in your network

and configured to handle call processing

If you want Cisco IP Communicator to auto-locate its TFTP server, you also need

an IP network that supports DHCP with Cisco Option 150 configured with the

address of your TFTP servers.

If you want to use Cisco Emergency Responder (CER), you need an available

ethernet port on a Cisco ethernet switch. For details, see the Cisco Emergency

Responder Administrator Guide.

Note If the computer on which Cisco IP Communicator is running is plugged into the

PC port on the back of a Cisco IP Phone, Cisco IP Communicator will not be

discovered by Cisco Emergency Responder (CER) software. In this case,

Cisco IP Communicator’s CDP (Cisco Discovery Protocol) is blocked and cannot

be detected by CER. Connecting directly to a switch port prevents this problem.
