Converged phone networks simplify support and management.

Article Summary:

Cisco IT in India was required by the local telecom regulator to merge separate PSTN and VoIP infrastructures without merging the calls, and to implement the convergence in a manner acceptable to the regulatory body. Cisco combined both infrastructures onto a single Cisco Unified Communications Manager (formerly Cisco CallManager) cluster that was configured with virtual partitions to maintain the separation between PSTN and VoIP calls.

Benefits Cisco realized from converging the PSTN and VoIP infrastructures in India included:

  • Eliminated a second phone and voicemail box for every employee, which has helped to increase employee productivity
  • Consolidation into a single network infrastructure for simpler support and management
  • Freed up nearly US$1 million in equipment that can be redeployed for new facilities, lowering capital expenditures
