Unified Communications Case Study: How Cisco India Simplified VoIP and PSTN calls with Logical Partitioning for Cisco Unified Communications Manager

New design allows a single phone line for all calls while reducing costs, simplifying dialing and maintaining regulatory compliance.

This case study describes how Cisco IT has evolved the deployment and configuration of its Cisco® Unified Communications Manager (Cisco UCM) clusters to support both PSTN and VoIP calls on a single system while meeting regulatory requirements for call separation. To reduce telecom expense, Cisco India wanted to merge the physical aspects of the two network infrastructures without merging the calls. The goal was to create a merged network design that would be acceptable to the local regulatory body. One solution in meeting this goal was creating aLogical Partitioning design for Cisco UCM, which routes Cisco India calls appropriately depending on the caller's location and the phone number being called. Cisco IT and Cisco employees are now realizing several benefits from Cisco UCM Logical Partitioning, including:

• Reduced costs by eliminating duplicate infrastructure and increasing on-net calling when appropriate.
• Placing calls is simpler for employees, whether they are calling from their desk, another Cisco office, or making business calls from home.
• Support for new communication services such as Extension Mobility, Cisco WebEx® Connect soft phones, and presence information.
• Simpler system management from a significant reduction in the number of call routing patterns.
