I used Wireshark recently to verify the CoS markings on Cisco IP phones during calls. The frames on packets travelling between phones shows CoS 5 on call traffic and CoS 3 on control traffic. When a call is received from an outside DID, the IP conversation is between a Phone and the Call Manager. In that case I still see the CoS 5 & 3 Markings on packets coming from the phone. However, the packets coming from the CM appear to have CoS 0 for all traffic. Shouldn't the CoS on traffic coming from the CM be marked with CoS 5 & 3 as well? Is that a configurable on the CM?
