An application might temporarily lose internet connectivity when its user moves between internet connection points. For example, a disconnection could occur when a user is roaming between cellular networks, or when a device switches between an LTE mobile data connection and a home wireless network connection.

The Vivox SDK provides network connection recovery functionality for connection loss of up to 30 seconds. When connection recovery is enabled for an application, the application can automatically reconnect to a session after a network change in scenarios where the Vivox SDK retains CPU continuity.

If a session resume fails after the application attempts to reconnect to the network, a event fires.
