Conference function with the newest version is a big downgrade. Did you ever try to setup a quick conference call with a mobile device? When it opens up this webclient suddenly but you don't have the password with you? And when you finally found it, it's opening a website which is not optimized for mobile devices ad the only thing you see is the menu on the left side? Then this conference setup becomes kinda challenging. Now in my case I have some bridged systems. I can see users from the other systems. I can add them to the conference call. But when I save and send the invitation, these guys dissapear. For whatsoever reason it only works, if I type in the persons email address manually. 3CX please fix this mess!
