Welcome!
We are proud to introduce our CTI premium/CRM client for Windows. The CTI premium / CRM client is optimised for the telephone system. CTI premium / CRM for Windows has been designed to make your phone easier and more convenient to use. It can do this in a number of ways as with presence management, chat or available CRM/ERP systems and this document will show you how.
We hope you enjoy using your CTI premium/CRM for Windows.
The CTI (Computer Telephony Integration) client uses your computer as a remote control for your desk telephone. We offer you two licence options, one with and one without CRM integration. You have the option to integrate CRM and ERP systems into the client as well.
Integrate various Customer Relationship Management (CRM) tools to the NFON telephone systems with CTI premium/CRM for Windows. The resulting shortened work processes lead to increased productivity and efficiency at work.
This document will provide you detailed insights into installation and usage of CTI premium/CRM to make your phone easier and more convenient to use.
A local server installation is required to use CTI premium/CRM for Windows. The server is provided by NFON, however, not hosted by NFON. Server installation and configuration are carried out remotely by NFON.
The NCTI premium client requires the uaCSTA protocol for communication. Therefore the client is only compatible with selected devices.

Find a quick start guide to configure and initialy operate your NCTI premium client:
Due to discontinuing the operating system Windows XP on April 8, 2014 and Windows 7 on January 14, 2020 as well as the Windows server 2003 on July 15th, Microsoft no longer grants support and updates to its users. Therefore, the CTI premium/CRM client is no longer officially supported with Windows XP or Windows 7 or with Windows Server 2003.
Furthermore, for security reasons we highly recommend to not use CTI premium/CRM with Windows Vista as TLS 1.2 is not available for Windows versions as Windows Vista or XP. According to the Federal Office for Information Security, TLS 1.2 is the minimum standard for the transport encryption via TLS (Transport Layer Security).
