Hi Andreas, in our network, we handle this as follows:-
1) we make sure that the PBX is marking the packets with the DSCP tags correctly. 2) we make sure that the phone/iad are marking the packets with DSCP tags correctly. 3) we make sure that the Radios (AP & CPE) are using firmware that respects the DSCP Tags, and provides them with appropriate priority 4) we don't do anything on our routers (in our network). if we have to, the only thing we do on the customer router (Dmarc) is to make sure that the dscp tags are correct. And this works very well for us. Regards.
