Cisco VG310 Voice Gateway - VoIP Phone Adapter - GigE - Analog Ports: 24 - 1U - Rack-mountable - VG310-EM

• 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 VG310 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.
• 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).

The Cisco VG Series Analog Voice Gateways are Cisco IOS software-based. The Cisco VG310 is a 24-port gateway. The gateway connects analog phones, fax machines, modems, and speakerphones to an enterprise IP voice system, so you can use them as extensions to your Cisco or third-party IP call-control system. Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness. The Cisco VG Series supports high to low concentrations of analog voice ports for modem calls, fax calls, and analog supplementary services.
The VG310 is built on the Cisco 2901 platform, powered by a single high-performance core processor. It provides high availability during power failure through an external universal power supply (UPS).
