QoS Voice not hitting my policy map

[eleevercc]

Hi QoS Gurus, 

This is my first time to write in Cisco and have to say that new to QoS technologies and i was hoping i could get some recommendation on my issue. 

Basically we just migrated all our IPTEL to a cloud based setup and now we have setup all of our QoS for voice to be prioritized as we have noticed that the voice quality is garbled (sound robotic) 

Although my main issue is, i have configured my own QoS to prioritize voice traffic but i cant see that any traffic passing through that policy map. Below is a quick glance on how the traffic goes

(Internet - Cloud Telephony) -->ISP Facing CISCO1921-->MPLS Cloud -->CISCO1921 -->IP Phones

I understand that i need to configure the QoS in our CISCO1921 but it seems i am not getting all voice traffic to hit the policy map that i have created and to complicate things, we are using a subinterfaces. facing internet and mpls (which i am not sure weather qos would work in this setup) 

ISP Facing CISCO1921

GigabitEthernet0/1 unassigned YES manual up up
GigabitEthernet0/1.898 xx.xx.xx.xx YES manual up up (MPLS)

Hoping for your kind patience and understanding :)

Hi 

You want to apply qos on interface g0/1.899?

This interface is building an ipsec tunnel with your voice provider. On that interface you need to add the command qos pre-classify to be able to apply qos on the traffic passing through it.

The service-policy has to be applied on sub interface.

Also your class-map is configured with a match-all and you have multiple match statement. If you want to have a traffic matching one of those then you need to modify it with match-any keyword.

Thank you for for the urgent reply.

When i tried to apply qos pre-classify it seems the command is not available.. i was actually having a doubt weather QoS feature is even activate in this router as i there was no option for me to activate the qos via mls qos but noticed that i can create all the class map and policy map.

Sorry, you're not using a tunnel interface.

You need to apply qos pre-classify under the crypto map configuration.
