# Backup terminals

Here you see the backup terminals if Dual Homing is configured and the communication server is used as a backup communication server for Mitel SIP terminals by other primary communication servers.

Apart from the type of terminal, the number, the user name and the MAC address, the overview list under the status parameter Registered also shows directly where the terminal is currently registered:

Table 1. Backup terminals
Parameter | Description of the parameter
Registered | This status is the normal case: the terminal is currently registered with the primary communication server. This status is the error case: the terminal is currently registered on this backup communication server since the connection between the terminal and primary communication server has been interrupted for some reason or other.
