Hi,
First I am assuming your gateway is using H323 or SIP...
You may not be able to see the exact radius attributes and values via a show command, but you can get same info from
"show call history voice"
If its an active call, "show call active voice", or "show call active voice brief".
Or you can enable calltracker. You can also specify how many entries to retain, etc.
Then view the calltracker history.
mssol-5300-15m(config)#calltracker history ?
max-size Maximum number of calls in CT's History Table
retain-mins Maximum time a call is kept in CT's History Table
mssol-5300-15m(config)#calltracker history
Make the call, then...
mssol-5300-15m#show call calltracker history
I do NOT recommend running the following command in a production network, but if one wanted to
see the exact radius attributes for voip calls, you could enable the following debug...
debug voip aaa
Hope this helps.
