Cisco VG204XM Analog Voice Gateway | SIP Gateway, Enterprise VoIP — CON-PSBU-ASR92U0E

Preserve analog voice services while you transition to IP telephony. Cisco VG204XM Analog Voice Gateway provides a practical bridge for organizations that still depend on analog phones, fax machines, or other legacy endpoints. It helps maintain continuity during migration projects, site refreshes, and phased UC rollouts where replacing every device at once is not realistic. Built for enterprise voice environments, this gateway supports a cleaner path from traditional telephony to SIP-based communications. It is well suited for branch offices, remote sites, and facilities where analog connectivity remains operationally important. By keeping legacy endpoints connected to modern call control, it reduces disruption and gives IT teams more control over rollout timing. For procurement teams, the value is straightforward: protect existing assets, avoid unnecessary endpoint replacement, and support a staged migration strategy that aligns with budget and operational constraints. For architects, it offers a dependable way to integrate analog devices into a broader IP voice design without overcomplicating the network edge. Ideal For Connect analog phones in a branch office to SIP call control Keep fax machines operational during a staged UC migration Bridge legacy telephony at remote sites with limited refresh budgets Extend the life of analog endpoints in facilities and back-office environments Why This Product 1 Keeps analog endpoints usable during IP migration 2 Provides 4 FXS ports for legacy device connectivity 3 Fits phased rollout strategies better than full endpoint replacement 4 Supports enterprise voice continuity at branch and remote sites
