Analog Phone Connectivity
The Cisco VG350, VG224, VG204XM, and VG202XM are ideal for analog phone deployments ranging from
centralized to sparsely concentrated or distributed topologies. These analog voice gateways provide a high level of
availability at locations with MGCP fallback, with ease of manageability using Cisco IOS Software monitoring
features. They offer many supplementary analog calling features depending on the call control and signaling type
used. Refer to Table 1 for the supplementary analog calling features available.
