Clustering over IP WAN can support two types of deployments i.e., Local Failover Deployment Model and Remote Failover Deployment Model. There are basically four types of deployment models in Cisco Unified Communications Manager architecture. This deployment model maximizes the utilization of available bandwidth by allowing voice traffic to share the IP WAN with other types of traffic. •Aggregate PBXs for migration to Unified Communications System—Unified CM Session Management Edition provides an aggregation point for multiple PBXs for migration from legacy PBXs to Cisco Unified Communications System. New Integrations for more Powerful Provision Automation. --> An IP WAN carries voice traffic between the distributed clusters. Although this design offers some redundancy, there is the risk of overwhelming the backup server if multiple primary servers fail. What models of Polycom IP conference phones are compatible with CUCM? For additional information on the deployment models, refer to the Cisco Solution Reference Network Design (SRND) guides and related documents available at: Cisco Intercompany Media Engine (Cisco IME) is a variation of a multisite deployment with distributed call processing, but with Cisco IME, the sites are separate enterprise organizations.

Following our successful article Understanding Cisco Dynamic Multipoint VPN - DMVPN, mGRE, NHRP, which serves as a brief introduction to the DMVPN concept and technologies used to achieve the flexibility DMVPNs provide, we thought it would be a great idea to expand a bit on the topic and show the most common DMVPN deployment models available today. Walks through bringing CUCM online, deploying endpoints, and setting up users. Long distance calling for each site uses the WAN for on-net calling. Conclusions and Recommendations. The IP Phones at the remote sites registers to the CUCM located in the central site. In a multisite deployment, with a single or multiple CUCM clusters, dial plan design requires the consideration of several issues that do not exist in single-site deployments: I am the Administrator of the website TheCollabGuru.com. The Clustering Over IP WAN Call Processing model is designed for organizations with large user populations across multiple sites that are connected by an IP WAN with the QoS features enabled.
