Cisco Cisco IPCC Web Option Leaflet

HTTP communication is performed between the SMC applet and the SMC servlet running on the CAD 
Base Services machine. HTTP is also the protocol used by the IPPA service and CAD-BE applet to 
communicate with the Browser and IP Phone Agent service.

The UDP/TCP traffic shown in the figure represent the socket connections used to exchange messages 
between servers and clients, which includes the CORBA connections used by most of the clients to 
request services and information from the servers.

The SMC servelet that runs on the CAD Base Services machine uses SNMP to gather status information 
on all the CAD services that are part of an installation.

When the Cisco CTI Toolkit Desktop is deployed in a network environment where two or more 
disjointed networks are interconnected using NAT, then Unified CM, the physical IP Phone, the Cisco 
CTI OS Server, the Cisco CTI Toolkit Desktop, and the Cisco CTI OS IPCC Supervisor Desktop must 
be on the same network.

Beginning with Cisco Unified CCE Release 7.0(0), Cisco recommends that you install CTI OS and CAD 
Services (including VoIP Monitor and Recording) on the PG. This does reduce the supported maximum 
agent capacity on the PG. If the supported PG capacity numbers provided in the chapter on 

, are not sufficient and you want to run these software 

components on separate servers to increase agent capacity on the PG, then prior approval from the 
Unified CCE product management team is required.

Legacy deployments where CTI OS or CAD Services were previously installed on separate servers are 
still supported. However, customers are encouraged to migrate CTI OS and CAD Services onto the PG. 
For more information regarding deployment configurations, see the chapter on 

.

Unified CCE deployments can support a mix of CAD and CTI OS agents on the same PG. If a mix is 
deployed, the sizing limitations of CAD apply.   Note that Cisco Supervisor Desktop (CSD) can monitor 
only CAD agents, and the CTI OS supervisor application can monitor only CTI OS agents.

CAD, CAD-BE, and the CTI Toolkit Desktop support the use of Cisco IP hardware phones and/or the 
Cisco IP Communicator software phone.

Some CAD agent application features (CAD, CAD-BE, and IPPA) require particular phone models, and 
some installations support either hardware phones or software phones but not both. For information on 
the exact phone models and IP Communicator versions supported, refer to the CAD documentation 
available at 

.

Silent Monitoring of agents is supported using either IP hardware phones or the Cisco IP Communicator.
