First at the interface level, you need to enable WMM.
Then I set up the following rules which ensures that DSCP sets layer 2
priority WMM needs:
"/ip firewall mangle
add action=set-priority chain=prerouting comment="VoIP WMM " disabled=no
new-priority=from-dscp passthrough=yes protocol=\
udp "
Most VoIP services tend to use DSCP of 46.
Then I set a somewhat broadbase firewall/queue rule which basically says
UDP packets should get preference since 99.9% of VoIP is UDP and I make
it the first queue rule before all others.
"/ip firewall mangle> add action=mark-packet chain=forward comment=VoIP
disabled=no in-interface=ether1 new-packet-mark=VoIP \
passthrough=no protocol=udp"
"/queue simple
add burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s comment=""
direction=both disabled=no dst-address=0.0.0.0/0 interface=all \
limit-at=0/0 max-limit=0/0 name="VoIP Traffic" packet-marks=VoIP
parent=none priority=1 queue=synchronous-default/synchronous-default \
total-queue=default-small"
These rules can be massaged quite a bit to be more specific since a lot
of other apps use UDP too. Some things we'll do to make the rule more
specific is find out the users VoIP provider and then setup the queue
based on the VoIP's IP block.

We enabled it both in the CPE and AP. We also added queue rules in
both the CPE and AP to ensure that VoIP traffic got priority not just
at layer 2, but layer 3.

Did you do that in your firewall, the ap, or both?

We enabled WMM on our Mikrotik's and then just added a Mangle
rule to
ensure the DSCP was marked correctly, this solved VoIP issues
for our users.
