Hi community,

Can you share your idea can we prevent VOIP traffic like skype, kakaotalk, wechat, line...? If we can, how to do it, in general?. Because as far as I know these applications are peer-2-peer and use dynamic ports and update version very quickly.

The version I concern is

Used version of Line: 3.9.3

Used version of Kakaotalk: 4.0.3

Used version of Wechat: 5.0.1

Thanks and regards,

HIeu
