Standby status indicates that Zello cannot send a message to a user in real-time. It occurs under three conditions:
- When a device loses Internet connection due to loss of WiFi or cellular service
- When the user has turned off their phone or stopped Zello from running
- When the user changes their Status to "Offline" to stop receiving messages.
Standby status cannot be selected by the user. It is automatically set when one of the three conditions occur and automatically reverts back to Available or Busy status when the connection is re-established or the user logs back on.
Additionally, new users added to the network will be automatically set to "Standby" status so that they may begin receiving messages before logging in for the first time.
How Standby affects messages from contacts
When users are placed in Standby due to a lost connection or Zello is not running, missed messages will be queued and played when the user is back online and in Available status. The messages are automatically played in the order that they were received. If the user was in Busy status prior to going into Standby, the missed messages are sent to the Conversation/History screen.
If push notifications are enabled, the user will see a notification when they receive messages while in Standby. Note that push notifications need an internet connection to be delivered.
When a user selects Offline status, the user is shown as in Standby status to other users and contacts can continue to send messages to the user. In order to receive the messages, the user must sign in before the messages are removed from our servers.
In this example, user "zellouser888" has changed the status to "Offline" and will not receive messages and only push notifications (if turned on)
On Contact lists, the status for "zellouser888" will display as "Standby" until the user changes from "Offline" to "Available", "Busy", or "Solo"
How Standby affects messages from channels
Unlike contact messages, missed channel messages while in Standby are not queued for playback once the connection is re-established. Missed messages cannot be recovered but another user on the channel can share the missed messages with the user.
Channel Alerts will be sent as push notifications to users in Standby status if the originator of the Channel Alert has selected to alert all channel members, whether connected or not.
