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
•
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.
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.
