NIM-2FXO= Use Case
Hybrid VoIP Migration: Seamless PSTN Trunking Integration
In a mid-sized enterprise transitioning from legacy PBX to VoIP, the NIM-2FXO-2PORT NETWORK INTERFACE MOD FXO UNIVERSAL links two analog PSTN trunks directly into the Cisco ISR router. This ensures uninterrupted inbound/outbound calls during the IP migration, reduces hardware complexity by 25%, and accelerates time-to-service without requiring a full PBX rip-and-replace.
Enterprise Call Center Telephony Failover
A global call center deploys the NIM-2FXO-2PORT NETWORK INTERFACE MOD FXO UNIVERSAL as an on-premises PSTN backup for its primary SIP trunks. In the event of VoIP carrier outages, calls automatically redirect over the FXO ports, maintaining 99.99% availability, preserving customer service levels, and eliminating revenue-impacting downtime.
Remote Branch Analog Line Consolidation
A retail chain with 50 remote outlets uses the NIM-2FXO-2PORT NETWORK INTERFACE MOD FXO UNIVERSAL to aggregate two local analog lines at each site into the corporate VoIP network. This centralizes call management, reduces per-site telecom costs by 40%, and simplifies maintenance with a uniform Cisco ISR platform across all branches.
