In some cases, such as when an application is suspended in the background, the connection to Vivox services can be disrupted so that voice communication terminates without signing out the user. In that case, a

vx_evt_media_stream_updated

event will fire with a state of

session_media_disconnected

and a non-zero

status_code

Note

An event that indicates the media stream has disconnected is not guaranteed to occur before a reconnect failure and user sign out.

The following sample code is an example of how to handle media stream updated events.


void HandleMediaStreamUpdatedEvent(vx_evt_connection_state_changed &evt){    vx_session_media_state media_state = evt.state;    if (evt.state == session_media_connected)    {        printf("Connected to voice session %s\n", evt.session_handle);    }    else if (evt.state == session_media_disconnected)    {        if (evt.status_code != 0)        {            printf("Disconnected from voice session %s with status %d:%s\n", evt.session_handle, evt.status_code, vx_get_error_string(evt.status_code));            // Expect a session_removed event to follow.            // Wait to re-join the session until after the network connection is restored.        }        else        {            printf("Disconnected from voice session %s\n", evt.session_handle);        }    }}
