Callback

[2rgrobla]

Hi all,

i have a 3640 Router for Dialin Win-Users with callback enabled. With IOS 12.2(6) all works fine, but another 3640 with IOS 12.2(2)T can't callback.

The errormessage is: ISDN BR2/0: Error: Unfound B-channel on Progress

after callback timer expired. i can't update the IOS at this time.

any ideas

Thanks

Looks like a bug CSCuk26988 which is solved in 12.2(05.02)T ( and 12.2(05.04) which explains why you don't see it happen in 12.2(6).No workarounds known.
