VoIP Gateways

The Cisco® VG350, VG320, VG310, VG204XM, and VG202XM Analog Voice Gateways allow you to use your IP telephony solution with traditional analog devices while taking advantage of the productivity afforded by IP infrastructure.

Unified communications enables organizations to collaborate more effectively and streamline business processes. Reach the right resource the first time. Improve productivity and profitability. Even in an IP world, however, many organizations still use analog devices such as phones, faxes, and modems, and want or need to continue to after migration to IP telephony. Important use cases for analog gateways include:

• Budget constraints during migration to unified communications: You don't have to replace your entire phone system as you move to unified communications. Cisco VG Series Gateways help you migrate at your own pace and budget: you can enjoy the benefits of unified communications and still use your existing analog devices.
• Meeting regulatory requirements: Many countries or industry markets require analog devices in certain use cases. Using Cisco VG Series, these organizations can still meet regulatory requirements but also have the benefits of unified communications.
• Environments that require phone service but do not have power and require long loop lengths: Examples include ranger stations, phones along railroad tracks, and some military deployments such as remote outposts.
• Harsh environments: Industries such as mining and manufacturing have harsh environments in which analog phones often have better endurance.
• Requirements for lighter IT infrastructure: Analog phones need fewer switch ports and have no power requirements.

The Cisco VG224 is a Cisco IOS Software-based high-density 24-port gateway for analog phones, fax machines, modems, and speaker phones within an enterprise voice system based on Cisco Unified CallManager. Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness. Commercial businesses can also use the Cisco VG224 with Cisco Unified CallManager Express to effectively augment an integrated services router (ISR) environment. Either topology environment will support business needs for a high concentration of analog voice ports for modem calls, fax calls, and analog supplementary services. The Cisco VG224 offers Cisco IOS Software manageability with 24 analog phone lines to be used as extensions to the Cisco Unified CallManager or Cisco Unified CallManager Express system in a very compact 19-inch rack-mount chassis.

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.

The Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways are analog voice gateways for the service provider, commercial, and enterprise unified communication markets. These voice gateways provide voice connectivity to devices such as analog phones, fax machines, and modems.

The Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways provide support for 2-FXS (Cisco VG202 and Cisco VG202XM) and 4-FXS (Cisco VG204 and Cisco VG204XM) ports and parity with Cisco IOS fax/modem, security, and Session Initiation Protocol (SIP) features. These voice gateways can be configured with Cisco Unified Communications Manager Express (CUCME) or Cisco Unified Communications Manager (CUCM).
