Hi, I would like to request the re-instatement of the ability to create an ad-hoc conference with a number not stored in the telephone book. This is when using the Windows 3CX client. Up until the v15 upgrade users were able to (mid-call) press the 'Conference' button to create an ad-hoc conference, then click the + button to add a number of their choice, not stored in their telephone book. Since the upgrade the users now have to have the user in the phone book in order to add another user. This is a feature requested by 3 of our clients.
