Hi there, I recently just upgraded to V15 from V11 and I am getting used to the changes with 3CXPhone for Windows. Previously I had been using the old 3CX MyPhone, and it served its purpose pretty well. It was mainly used for setting up conference calls for our clients. Right now, I have about 100 extensions in my system. We are using this system across 3 different buildings with 10 different clients all on the same system. We have some high profile clients, and I would like to know how I can restrict access to the phone book. As it stands right now, if you click the dialer, you immediately see every extension on the system as well as the name associated with it. It would be very helpful if a user could only see the phonebook entries associated with their group (as they are grouped by client). How would I go about doing this? Thanks!
