Hi Experts,

I want debug isdn messages by a specified DNIS, anyone knows this command?

Qazzaq,

If your IOS supports you can use per call debugging feature on the gateway

conf t

call filter match-list 1 voice
incoming calling-number XXXXX  (or)

outgoing called-number XXXXXX (or )

incoming called-number XXXXX

then in exec mode

#debug condition match-list 1

Now run your debug isdn q931 debug

## debug isdn q931

No you cant do that the debug isdn q931 does not let you further specify based on DNIS,

you would need to capture the output in a log file and open it in something like notepad ++

Thanks for your reply, Dennis... But it's really hard if i want to trace a specific call, in my environment, VG 3945 connect 16 E1 and cps can almost reach 50 at peak hour...
