We had a major step back with the 15.5 SP2 update on the Audio Conference scenario. Previously, all Conferences where made inside the clients, Either Windows, Mac, Android or IOS. The user created all conferences, invited guests, received invites, edited, etc... INSIDE the clients. Now, when you click on conference, it sends the users to a website! Problems here: 1- The Website has Certificate problems, which scares the users 2- The user must login again, using a Password he never had. 3- This password can´t be changed by the user himself! We need to provide it administratively! If we provide an easily remembered password, we will be risking that our Conference rooms may end up being used by hackers or so... If we provide a strong password (Like we used to, as only the client softwares, not the end users, were using this password before), the user will not be able to remember it when we wants. 4- We need to expose the https port of our 3CX servers, which we didn´t had before 5- The website is messy, doesn´t allow to invite users and doesn´t send the invites by email! So, as we can see, this was a major step back. So, just please go back for the old and good inside the clients solution. It was working just fine, and was one of the strenghts of the 3CX solution!
