I’m new to MikroTik and loving it already: replaced a core router for a 4-tenant office building and it’s been smooth as glass. Already feeling sheepish about the amount of time I’ve spent grokking Cisco IOS. To say nothing of the money. 
I’m evaluating performance as I go and implementing only what I really need to in terms of restricting things. The most important thing here is VoIP quality, and while recent bandwidth upgrades seem for the moment to have solved that I want to get ahead of it.
Before I get into the deep water of full-fledged QoS and multiple classes of packets, I wanted to see if anybody here could comment on this: on my home network, I solved this with DD-WRT. Set it up to do absolutely nothing on downlink, and mark the outbound RTP (10000-20000 in my case) as “premium”. Super simple and made my home VoIP traffic impervious to big uploads.
So, what I’d love to know is the simplest way possible to do the same thing in the MikroTik world. I’m already prowling forum posts and seeing more complex implementations with different tiers for HTTP vs SSH/telnet vs VoiP vs FTP, but what about just “send RTP out the door ahead of everything else and leave it at that”?
