Maintain analog voice services during a measured move to IP telephony with the Cisco VG204XM Analog Voice Gateway. Built for environments that still depend on legacy handsets, fax machines, or paging circuits, it provides a practical bridge between traditional voice endpoints and SIP-based communications. For organizations with mixed telephony estates, this gateway helps protect existing investments while reducing the operational friction of a full cutover. It is well suited to branch offices, distributed facilities, and sites where analog endpoints remain essential to daily operations. By keeping those devices connected through a managed gateway, teams can align voice modernization with budget cycles, site readiness, and support windows. Cisco’s enterprise heritage matters here.
