Hi Yes, done this many times.
Create a group policy for 5060/TCP QOS AF31 26 this is for sip signalling of your sip endpoint, you could do the same for wde connections as well .
For voice traffic 16384-32768/UDP QOS EF 46 for voice packets
All of this depends on your config, you could also just do this at the network switch.
