ISDN call drops after undebug all

ISDN test call doesnt get established if debug for q921 / 931 is not turned on. ISDN test call gets connected only if these commands are on. The time undebug all is done call is dropped. As seen in the show isdn act command.

Secondly is it mandatory to see "Layer one activated" and "miltiple - frame - established " , when we give Show isdn status command ?

Thanx in advace.

Re: ISDN call drops after undebug all

humm ...

IOS version?

maybe a bug, I think.

If you could, try 12.0(7)T, the best version for ISDN dialup.

'isdn test call interface' just rings 1 time, correct?

Please let me know

Regards

Andrea
