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.
