- General Details
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.
● Familiar Cisco IOS Software-based hardware: The hardware includes uniform Cisco command-line interface (CLI) and Simple Network Management Protocol Version 3 (SNMPv3) support for ease of gateway configuration and operation.
● Robust voice quality: Cisco experience in providing toll-quality packet-voice service helps ensure that the Cisco VG350, VG320, VG310, VG204XM, and VG202XM provide the clear, robust voice quality end users have come to expect from telephony services.
● Low- to high-density solutions: With solutions from 2 to 160 ports, organizations can have the right-size platform for the right-size deployment.
● The VG310 and VG320 can support foreign exchange office (FXO), foreign exchange station (FXS), T1/E1 Primary Rate Interface (PRI), channel associated signaling (CAS), and Basic Rate Interface (BRI) 2- and 3-port voice interface cards (Cisco VIC2 and VIC3, respectively).
● Cisco EnergyWise® support: Lower per-port power consumption is supported on the VG350.
● Support for long loop lengths: Loop lengths up to 30,000 ft (9,144m) are supported.
● Interoperability: Cisco VG Series works with Cisco and third-party IP private branch exchanges (PBXs).
● High availability: With these gateways you will experience less voice downtime due to WAN link failure. The Cisco VG Series has built-in Media Gateway Control Protocol (MGCP) failover to an H.323 connection to a Survivable Remote Site Telephony (SRST) router. This failover maintains voice service for analog endpoints if the WAN link fails or you lose connectivity to the Cisco Unified Communications Manager, Cisco Business Edition, or Cisco Hosted Collabortion Solution (HCS).
