Unified CVP
Advantages
•
Component location and administration are centralized.
•
Calls are treated and queued locally, eliminating the need for queuing across a WAN connection.
•
There is less load on Unified CM because Unified CVP is the primary routing point. This allows
higher scalability per cluster compared to Unified IP IVR implementations. See

Best Practices
•
WAN connections to agent sites must be provisioned with bandwidth for voice as well as control and
CTI. See
CTI. See
more information.
•
A local voice gateway might be needed at remote sites for local out-calling and 911.
