I have two questions regarding the instructions for the Call Control API which prescribe: 1. What should the addition to the 3CXphonesystem.ini file look like? This probably seems a stupid question since an example is given in the excerpt above, but that example looks nothing like other lines in the .ini file (having a period in the key and white space around the equals sign), and it coincides exactly with the code one must write in his .NET application code. (Moreover, whoever wrote it used "smart" quotes.) 2. Must I restart my 3CX Phone System after changing the .ini file? And what kind of down time will that cause? Will it disconnect all existing phone calls? Will it preclude new inbound or outbound phone calls during the restart process?
