QoS only takes effect when there is congestion, so, to test it, you need to create some congestion on your link.  Try doing a couple of large file transfers and or FTP sessions across the link at the same time as your test call and see what happens.

Another way, would be to inspect the policy-map counters, even if the link is not congested. What type of equipment is your WAN/SP edge?

For example, you could use sh policy-map <inf_id> to inspect a policy map's class counters (to see if packets are matched on the voice/video classes) and sh mls qos interface <inf_id> statistics to see if you properly receive COS/DSCP tagged packets.

If packets you have packets matches, then you can monitor during the day to see if the thresholds defined on the voice/video class are overrun.
