I've found the QoS questions are very specific to test a certain area of knowledge. They are not looking for what we would consider a "best practice" system wide. I think we could skip setting the DSCP values in CUCM. If you think the question calls for it you can have your class-map match both AF31 and CS3 for signaling.

I was planning on doing that myself. As to changing the DSCP values, it all depends on what they ask for in the QoS section of the test is all.

This way I can avoid and undesirable presets. Let me know your thoughts on this. Also why are you setting DSCP for Phone Configuration and DSCP for Cisco CallManager to Device Interface to AF31? Default CS3 should be good, let me know if I'm wrong on this?

The one thing I'm really struggling with is mapping out my dial-plan during my read through of the lab. I would love to hear what others are doing. I have also been building base router configs for h323, gatekeeper, mgcp, srst,sip, etc so that I can practice quickly configuring those on the routers. One of the things I haven't really been keeping track of are some of the service parameters that I should adjust out of habit. Here are a few that I can think of off the top of my head that I plan on tweaking at the start of the exam. Please feel free to add to them. Enterprise Parameters DSCP for Phone Configuration - Set to AF31 DSCP for Cisco CallManager to Device Interface - Set to AF31 Change the Phone URL's to IP's Organization Top Level Domain Cluster Fully Qualified Domain Name Service Parameters - CallManager T302 Time - Know where it is if you need ot change interdigit timeout Call Classification - Offnet Builtin Bridge Enabled - True Device Name of GK-controlled Trunk That Will Use Port 1720 - Set as needed. Transfer On-hook Enabled - True (Also a great thing to do in production when migrating users from other phone systems) Block offnet to offnet transfers - Know where it's at. Auto Call Pickup Enabled - True Call Back Enabled Flag - True (Verify) Single Button Barge/CBarge Policy - Set to Barge unless otherwise directed. Stop routing on Unallocated Number Flag - False - H323 redundancy Preferred G.711 Millisecond Packet Size - 20 (Verify) Preferred G.729 Millisecond Packet Size - 20 (Verify) G722 Codec Enabled - Disabled (Unless otherwise directed) Intraregion Audio Codec Default - G711/G722 (Verify) Interregion Audio Codec Default - G729 (Verify) Automated Alternate Routing Enabled - True (This one gets me every time on AAR so I turn it on by default now) Enable Mobile Voice Access - Set as required Mobile Voice Access Number - Set as required System Remote Access Blocked Numbers - Set as required Service Parameters -Cisco IP Voice Media Streaming App Supported MOH Codecs - G711 mulaw and G729 Annex A HTH Bill Hatcher _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com<http://www.ipexpert.com> Are you a CCNP or CCIE and looking for a job?
