Hi to all!
I’m new in the world of Mikrotik! 
I’m working with a MPLS/VPLS based network in my backbone. All trunks are Ubiquiti Wireless. Then, to the customer I have AP and Station Ubiquiti also with pppoe for delivery internet service.
The problem that i have is: in some customer we put Cisco ATA (And start pppoe sesion here) to deliver VoIP service.
My Asterisk and ATA are marking the packet with correct DSCP (EF).
In all ROS (v6.41) i have a mangle configurated:
/ip firewall mangle
add action=set-priority chain=forward new-priority=from-dscp-high-3-bits
With this, i can see that the packet are marked with the correct DSCP over MPLS. What else i need to do to priorize the traffic?
The trunks never are full, the bandwidth is ok in all network.
Thanks in advance guys!
