Cisco Cisco IP Contact Center Release 4.6.2 Guia Do Desenho

Firewalls are supported between the CAD services and desktop applications and between the desktop 
applications as long as the firewall allows the required type of traffic through and the appropriate ports 
are opened. 

 shows the traffic types used between the CAD components.

For detailed port information, refer to the Port Utilization Guide for Cisco ICM/IPCC Enterprise and

 shows that IP voice streams are exchanged between the VoIP providers (CAD, the VoIP 

Monitor service, and the Recording & Playback service) and the VoIP requestors (CSD and the 
Recording & Playback service).

CTI and call control data (agent state, skill information, and call events) flow either from the CTI OS 
service (in the case of CAD) or from one or more of the CAD Base Services communicating directly 
with the CTI server (in the case of CAD-BE, CSD, and IPPA agents).

Note that, in the case of the IP Phone Agent XML service, the CTI information exchanged applies only 
for agent state changes requested by the agent using the IPPA application and for skill information 
displayed on the phone. Call control messages are still exchanged between the phone and Unified CM.
