That page was old and no longer correct. It was also made by some user, not by MikroTik. The documentation now will only consist of official and verified articles. All user ideas shall be posted in forum or other places.
The article references technologies that are not used anymore for many years (Skype has no more Supernodes).
I need to prioritize VoIP by IP address of phone in WAN trafic. Where can I found official information about this setting in Mikrotik RouterOS?
Thanks.
