between Unified CM and Unified IP IVR is not supported across the WAN in this model. Local
gateways also will need local redundant connections to Unified CM.
gateways also will need local redundant connections to Unified CM.
• The minimum cluster size using Unified CVP as the treatment and queuing platform is 3 nodes
(publisher plus 2 subscribers). However, a deployment with 5 nodes is preferable, especially if
there are phones (either contact center or non-contact center) local to the central sites, central
gateways, or central media resources which would require local failover capabilities.

• In a deployment with clustering over the WAN, the VRU PG could connect to a local IP IVR or
Unified CVP or to a redundant IP IVR or Unified CVP across the WAN. For information about

• In a deployment with clustering over the WAN, the Unified CM PG must be on the same LAN
segment with the CTI Manager to which it is connected.
• Cisco Finesse does not support connection to the CTI Server over a WAN. All connections from
Finesse to the CTI Server must be local to a given location.
• Cisco Finesse does not support side A and side B Finesse servers separated over a WAN
connection. Both Finesse servers must be co-located in a single facility.
