Hello Experts,

I ran into an issue trying to verify the actual consumption of video and voice on a remote site.  Please look at the configuration
1. VPN and internet work with no problem
2.Video is transmitted but it is kind of choppy.  

Problem:
I was under the impression that the following commands should give me QoS but it is not working because the ACL-s  do not have any hits .  I am attaching the configuration

class-map match-all SipVoice
 match access-group 198
class-map match-all Video
 match access-group 199


What am I doing wrong?  I want to limit the amount of bandwidth.
How do I view what is being processed in the QoS?

Thank you

Probably same as this:

Due to NAT you need to apply it the QoS on the inside interface.

Hi good afternoon, it is not working :-(, I applied the Nat on the inside interface.

Do you recommend I run a specific debug?

You need to apply QoS on the inside interface. NAT should stay the same.

After that you should see some hits on the ACLs. Just note that if you are sending these packets over the internet, you may have some problems there because the internet actually strips these QoS markings. You would only have control of which packets go out first in your network, and no control on how they arrive.

Use SDM to configure QoS on your router, or if you move the QoS commands over to the inside interface and you see your ACL hit count increasing then the problem may be with your ISP... on either end. Try to use G729 as your codec if you havent already, this should lower the bandwidth requirement.
