Deploying IP Office as an Avaya Cloud Office ATA Gateway
Deploying IP Office as an Avaya Cloud Office™ ATA gateway
For IP Office R11.1.2.3 and higher, you can configure an IP500 V2A to act as an Analog Terminal Adapter (ATA) for analog extensions connecting to Avaya Cloud Office™ (ACO). In this mode, the IP Office uses an Avaya Cloud Office™ trunk to connect to Avaya Cloud Office™.
-
The features in this document are separate from using an IP Office to provide resilience for ACO J100 phones. For that feature see the Using IP Office as an Avaya Cloud Office™ J100 Persistent Gateway manual.
-
Avaya only supports using an IP Office as an Avaya Cloud Office™ gateway with IP500 V2A control units running IP Office R11.1.2.3 or higher.
-
Depending on the installed IP Office hardware, up to 376 analog extensions can connect to Avaya Cloud Office™ with a maximum of 40 simultaneous calls.
-
Emergency calls use the Avaya Cloud Office™ emergency service or a local IP Office trunk (analog, PRI, or BRI).
