conjunction with Cisco Agent Desktop and other background traffic across the WAN. These voice drops 
might occur with a specific number of agents at a certain link speed, and those possible scenarios are 
denoted by the entry N/R (not recommended) in 

.

In remote agent deployments, QoS mechanisms should be used to optimize WAN bandwidth utilization. 
Advanced queuing and scheduling techniques should be used in distribution and core areas as well. For 
information on QoS traffic classification, see

provisioning guidelines for centralized call processing deployments, refer to the Cisco IP Telephony 
Solution Reference Network Design documentation, available online at 

Security can be implemented on many levels. Applications security is clearly dependent upon security 
implemented at the infrastructure level. For more details on security at the network infrastructure level, 
refer to security design considerations in the Cisco IP Telephony Solution Reference Network Design 
documentation, available online at 

Aside from call routing, IPCC Express or IP IVR scripts often process enterprise data from existing 
corporate data stores such as a database or a corporate directory server for functions such as account 
authorization and order status. Often, these data stores already exist and share data with other enterprise 
applications.
