Prioritize VoiP with tos/dscp

Hi,

Im new here, my name is Dave, i have an issue with my mikrotik and is that i am unable to configure the priorization of Voip with tos/dscp in my mikrotick, the version is v6.15.

Anyone can give me a hand?

Regards

Take a look at this…

If you just want to change the dscp marking in pkts coming from an ata then all you need is a firewall/mangle rule like this.
chain=postrouting action=change-dscp new-dscp=46 passthrough=no protocol=udp src-address=192.168.88.254 log=yes log-prefix=“”

where src-address= your ata

An examplo of this without filter by IP?
