Scenario

Description
|
|
ACO Line connection not available
|
The IP Office will continue attempting to register the extensions with Avaya Cloud Office™ until successful.
When in this state, the IP Office system still supports emergency calls if using a local trunk.

IP Office power failure
|
If using a local analog trunk for emergency calls, depending on the IP Office hardware, some analog extensions can still make emergency calls. See IP Office power fail operation.
