IP Office Basic Edition - Phone Based Admin

This type of phone can be used for system, centralized and personal administration functions covered by this document. For system and centralized administration, the phone must be connected to one of the first two extension ports on the system.


The ETR 34 is physically similar but lacks a display and so cannot be used for programming.

The button numbering order on these phones does not depend on the system mode. However, the default button usage is affected by the system mode.

The programmable buttons are numbered from 01 left to right, bottom to top, ie. bottom left is button 01, top right is button 34.

For systems running in key system mode, the first two programmable buttons, 01 and 02, are fixed as Intercom 1 and Intercom 2 buttons. Buttons 03 upwards are assigned as line buttons based on the Number of Lines setting or the number of analog trunks installed in the system.

For systems running in PBX system mode, the first two buttons, 01 to 02, are fixed as call appearance buttons.


While being used in any of the programming modes, the function of some keys changes as indicated by the overlay template below.
