Is QOS working in my network?

Level 1

Hi All,

Its good to be here again and I'll specially want to thank all contributors to this forum.

Below is a sample configuration of my Router. I am trying to do QOS on the IPSEC VPN tunnel so that voice traffic can be given priority over other traffics (I am using non cisco IP phones).

I want to know if this config is ok and working because I have not noticed any improvement in voice quality, if not ok pls can someone give me a better suggestion? (I used SDM for the QOS configuration). Below the show run is a sho policy map output.
