The traffic from the IP phone is being marked. When I sniff the traffic I am not seeing the traffic from the phone but from the Call manager to the CME over the SIP trunk. This is the traffic that is not being tagged.

If the traffic from the IP Phone has been marked and qos is enabled on the switch, the ip phone traffic over the sip trunk should be marked too..IS QOS enabled on your switch?

Here is how my switchports and QOS are setup. I have also put the port for call manager here.

interface GigabitEthernet5/2

switchport access vlan 10

switchport mode access

switchport voice vlan 100

qos trust device cisco-phone

qos trust cos

qos map dscp 32 33 34 35 36 37 38 39 to tx-queue 4

qos map cos 3 to dscp 26

qos map cos 5 to dscp 46

When I sniff the traffic from the switch to my router I do not see traffic from the phone. I am seeing traffic from my call manager to the CME over the SIP trunk and it has no dscp marking.

on the switch ports for the CCM and routers etc add

mls qos trust DSCP

Do you have the appriopriate policy-maps and service-policy applied in the right direction on your router

Here is my policy-maps and serivice policy

I assume that your virtual multilink interface has been assigned to a pysical interface...

WHen you place calls between ccm and ccme, do you see the traffic matching the policies defined ont he interface..

\you can use the command.sh policy-map interface..command

Nope, that is how this all started. I was looking at the sh policy-map int and could see my queues not being used. then I started to sniff and could not see any markings coming from the call manager.

I'm not sure if you ever figured this out, but you won't see anything marked from your CCM. If you would like to see CCM packets being marked, make sure you have SCCP/SIP in your access-group. Voice packets never come from your CCM. Your CCM only sets up the call, after that the call is point to point.

But if it's a SIP trunk, the calls would go through that Trunk and you should be able to monitor that traffic correct? CUCM will setup the call between two end points, but if goes through a trunk on CUCM, then the packets should be seen correct?
