Need a QOS solution on 5510

We switched a customer over to VOIP recently and they are having QOS issues when the T1's max. What I found is the QOS policy on the router has not tagged anything VOIP related, IOW, it isnt seeing any EF bits. Somehow I beleive the ASA is not sending them through, or the phones behind the ASA are not sending them to begin with.

I need a simple solution to tag packets on the ASA to be marked EF from subnet. This way the router can see those marks and prioritize them properly.  The CCM and phones PAT off the ASA to our gateways.

The ASA is not capable of tagging packets for QoS:

It does preserve the DSCP tags though, so this probably means they're not being tagged to begin with.

You'll need to make sure the sources are tagging their own packets, or use another IOS device in the path to do the tagging for you.
