Scenario: A mid-sized enterprise deploys a Cisco ISR 4351 router at its remote branch and needs to integrate two legacy analog handsets for reception and intercom. By installing the VIC3-2FXS/DID-4 port FXS VIC, the IT team connects analog devices directly into the IP-PBX over SIP. Benefit: Seamless call routing and full UC feature parity (voicemail, call park), lower hardware and maintenance costs, unified management under Cisco Unified Communications Manager, and guaranteed business continuity.
Scenario: A regional hospital consolidates multiple analog fax machines and building-security alarm sensors onto a Cisco ISR 4431 gateway. The VIC3-2FXS/DID-4 module is configured in DID mode to assign dedicated inbound numbers and support T.38 fax over IP while also handling alarm line supervision. Benefit: HIPAA-compliant secure fax delivery, 50% reduction in PSTN circuit costs, centralized monitoring and alerting, faster incident response and streamlined regulatory reporting.
Scenario: A nationwide retailer with 50 stores requires unique inbound numbers for each location’s POS terminals and customer-service desk. By deploying Cisco ISR 4321 routers equipped with the VIC3-2FXS/DID-4 VIC in DID mode, they map four direct-inward-dial numbers per site to local analog endpoints. Benefit: 30% reduction in IVR traffic, lower long-distance charges, precise call analytics per store, and improved customer satisfaction through direct, location-specific routing.
