Branch Gateways work with Communication Manager software installed on any of the following servers to help deliver communication services to enterprises:
Avaya Solutions Platform S8300
You can migrate from Appliance Virtualization Platform Release 8.1.x on a S8300E server to Avaya Solutions Platform S8300 6.0 or later.
Customer-provided server
Infrastructure as a Service (IaaS)
Avaya Solutions Platform 130 Appliance: Dell PowerEdge R640 and R660xs
Branch Gateways connect telephone exchange and data networking by routing data and VoIP traffic over the WAN or LAN. Branch Gateways provide support for IP, digital, and analog devices.
Branch Gateways are controlled by Communication Manager operating either as External Call Controller (ECC) or Internal Call Controller (ICC). In a configuration that includes both ICC and ECC, ICC acts as a survivable remote server (SRS). ICC takes over call control when ECC fails or the WAN link between the main office and the branch office is down.
Branch Gateways also provide the standard local survivability (SLS) when the connection to the primary ECC fails and an SRS is not available. This feature is available only for IPv4 setups.
