ST 25
Data Sheet


    The ST25 digital system phone is suitable for connection to the internal ISDN bus of an AGFEO ISDN telecommunications system. The connection to the internal ISDN bus allows all the benefits of a system phone to also be enjoyed on the AC 141 WebPhonie plus and the modular expandable telecommunications systems of the Basic-Line. Also, the Business-Line and Profi-Line telephone systems can be extended to include additional system phones, even if all the Varioports are occupied - more system phones for more users.

    The ST 25 digital system phone allows you to have complete control over your ISDN system in a user-friendly manner: Speed dial keys and function keys for all features provide convenience telephony at the push of a button. And the large-format display keeps you permanently up-to-the-minute on the current status of the entire system.

    ST 25 - smart way to Phone
      People who spend a lot of time on the phone like to keep their hands free, which is why the ST 25 digital system phone comes with a headset connection!
      With a feather-light headset, the AGFEO TK-Phone software application and a PC, the ST 25 is turned into a professional teleworking workstation, for the switchboard operator or order processing staff for example. To toggle conveniently between handset and headset operation, just use one of the customizable function keys.
