Block send file via chat

[jackmanfredi]

Hello,
is possible to block the send of any type of files via chat? I see that is possible to specify some types of files, I need to block any type.
I already tried to use * for all files but this not works.

Files can only be sent by the 3CX agent in the chat, but there is no way to block this or specify which files can be sent.
