Error codes in Unify HFA IP phones (OpenStage and OpenScape Desk Phone CP)

The display of the OpenStage HFA phone sometimes shows error codes. This article lists the error codes clearly.

In this table you can find more hints about the displayed error:

Please note that the last part of the error code indicates the priority and this is updated to the highest priority of the errors present. For example: When the LAN cable is unplugged, the phone will first display LP1. After the connection between the phone and the system is broken, the phone would normally also display H02 as a registration error. However, since LP1 indicates a priority 1 error, the priority of the H0 error is updated from 2 to 1, so it is displayed as H01.
