    1  On-premise server installation required. Usage of NCTI premium clients is restricted to snom* and Yealink phones with uaCSTA firmware.

    *snom D862 and D865 are excluded.

    2  TAPI interface (32/64bit) for outgoing calls (outbound) as well as for incoming calls (inbound) available per default.

    3  TAPI client or TAPI server. TAPI interface (32/64bit) for outgoing calls (outbound) available per default. TAPI interface (32/64bit) for incoming calls (inbound) available on project basis for specific project prices.

    4  For the NCTI standard/CRM client the current telephone status/presence information ("busy"/"available") is set and updated automatically in Skype for Business. Full control of your telephone out of Skype for Business (dial, hold, transfer, toggle, volume control). Able to display incoming calls and name resolution with available contact data out of the Skype for Business address book.

    5  NCTI premium is in contrast to the NCTI standard/CRM client just able to synchronize the presence status. This means that the Skype for Business contacts are able to see if the user is busy. But users are not able to call out of Skype for Business.

    6  The softphone function of the desktop and mobile client with a NCTI pro terminal is possible within the Business Premium tariff.

    7  Please use standard firmware for the service portal.
