hi please how can block all voice on mikrotik 2.9.51.
i am using mt server in the university.and i found some student using usb phonejack in lab so pls how can block that
many thanks in advance
It’s virtually impossible to do. Skype, for example, encrypts it traffic and does not have a static port. You could block everything for the student and only allow access to approved IP addresses – in other words a whiltelist scheme. However, that’s a huge headache. You can sniff the traffic he’s using on this USB phonejack and then try and block that specifically as well.
