NOTE: Unfortunately, it happens from time to time that a freshly installed/licensed instance of PhoneSuite TAPI cannot connect directly to the server. Unfortunately the colleagues of PhoneSuite could not tell us yet, what causes this delay. It is recommended to install and license PhoneSuite in advance if possible. As a rule, the connection and thus the scanning of the devices works reliably the next day.

Test the TAPI functions

With some Windows systems, it may be necessary to define the own location. In this case, please open the "Phone and Modem" settings and edit the "Own location".

Location name: please enter a unique name here

Open the Microsoft "Dialer" and click "Tools → Connect via..." in the menu bar of the program.

In the "Connect via" window, select the line to be tested and confirm the selection with "OK".

3. Perform test call

Now you can enter a phone number in the "Dialer" window and make a call to it by clicking "Dial".

If you would like to adjust this behavior so that the "incoming" call is automatically accepted, please find out about the required setting option in your device/softphone. The required function is often called "Intercom" or "Automatic answer". Unfortunately, the designation varies from manufacturer to manufacturer and must therefore be taken from the respective documentation.
