To make a call by the GUI, double click on the desired contact (whether it is an internal user or a contact from the directory or an entry in the call list). If the contact to call is an extension of the switchboard, the call can only be made if the user in question has an active device and is in the idle state. To call an additional number of a user (mobile, home, etc.) right-click on the contact and choose the number of the contact to call
If the number to call is a new external number that cannot be traced among any of the company contacts, it can be dialed directly on the GUI interface in the upper left section. To dial the number, place the mouse cursor inside the box, type the number and press the ENTER key on the keyboard or the call buttonlocated on the side of the box..
