With revision 2473 of isnd4bsd this problem is solved:

-> asterisk -rx "core show channels" (before incoming call)
Channel              Location             State   Application(Data)
CAPI//-free          s@default:1          Down    (None)
1 active channel
0 active calls
0 calls processed
Asterisk ending (0).
-> asterisk -rx "core show channels" (during the call)
Channel              Location             State   Application(Data)
SIP/34-00000000      4994068@from-interna Ringing AppDial((Outgoing Line))
CAPI/ISDN_TE_1/49940 4994068@capi_telekom Ring    Dial(SIP/34,30,gj)
CAPI//-free          s@default:1          Down    (None)
3 active channels
1 active call
1 call processed
Asterisk ending (0).
-> asterisk -rx "core show channels" (after hangup)
Channel              Location             State   Application(Data)
CAPI//-free          s@default:1          Down    (None)
1 active channel
0 active calls
1 call processed
Asterisk ending (0).

I will do some tests and then update my production server and report the
results.
