I'm trying to capture the trace between call manager and one gateway. I already enabled the traces for h225 and h245 by click "set default". Set them as "detail" level. Update to all the nodes.
When I click "collect files" in RTMT, I chose the server and Call Manager Service and then set the time for collection. After the files were downloaded to my computer, I didn't see any information about h225 and h245. Do I miss something when I collect trace from RTMT?
Please help. Thanks.
h245 traces aren't on by default. Do you have that box checked?
h225 should be on if detailed traces are writing. An easy check to see if you have detailed traces on: do you see digit analysis for calls (search for dd=")?
Are you sure the gateway is doing H323 to the node which you collected the traces from? Are the calls actually successful? If the calls are failing, he call may be failing at L4, before CUCM gets the chance to process the h225 setup.
If you want to see h225/h245 traffic, you can grab that from the perspective of the gateway, which may help out some:
