go to the asterisk CLI (asterisk -r) and post the output of the "misdn show stacks" command. There is a number of reasons why you obtain a congestion tone. Anyway your bri connections are down, in fact the leds on the card blink only when connection is down on layer 1/layer 2.

I have similar problem
running ubuntu 8.04 hardy amd64 server
my ligths blink on b400p
when cable i connected but
when i call they go green
the when i hang up they red but not blinking
and then start to blink again.
Anyway i got diffrent problem
when i call from pstn to sip phone i do not here
the calling party but the party can here me.
I thing the problem is with amd64 but maybe i am wrong
could you send us you asterisk/misdn.conf so i can compare it
; set debugging flag:
; 0 - No Debug
; 1 - mISDN Messages and * - Messages, and * - State changes
; 2 - Messages + Message specific Informations (e.g. bearer capability)
; 3 - very Verbose, the above + lots of Driver specific infos
; 4 - even more Verbose than 3
; the big trace
; single call trace files
; set to true if you want to have them
; they depend on debug level
; users sections:
; name your sections as you which but not "general" !
; the secions are Groups, you can dial out in extensions.conf
; with Dial(mISDN/g:extern/101) where extern is a section name,
; chan_misdn tries every port in this section to find a
; new free channel
; The default section is not a group section, it just contains config elements
; which are inherited by group sections.
