I then added a context to match those, too.
Otherwise I would loose these calls.

Okay, but then the setting in capi.conf
  isdnmode=MSN
is wrong. For 'Anlagenanschluss' you need
  isdnmode=did

[General]
nationalprefix=0
internationalprefix=00
rxgain=0.8

language=deA

These options are no general options, these are for the port sections only:
immediate=yes
;immediate=yes
faxdetect=off

[ISDN1]
incomingmsn=*
context=from-extern
isdnmode=MSN
controller=1
group=1
callgroup=1
accountcode=ISDN1

echocancel=yes
echosquelch=1

Both of these do not make sense. Either your hardware does not provide
echo-cancel and you use echosquelch (which is something I cannot recommend)
or you have a DIVA with hardware echo-cancel and you set echocancel=yes.

echotail=64
devices=2

[cut]
ISDN3-5 like ISDN1
ISDN2 is in NT mode.

Hm, I was used to put an ANSWER() in front of every PLAYBACK(),
BACKGROUND(), VOICEMAILMAIN() and so on. And after I while I asked
myself whether it wouldn't be a good idea to put ANSWER() in front of
DIAL(), too, just to be sure that asterisk has control of the call. No
good idea? Could it cause an trouble? The wiki doesn't mention any
disadvantages.

If you want to play something to the caller (without having reversed early-B3 possibility), you need to ANSWER(). But if the caller just should
hear the ringing tone, let Dial() handle this.
E.g., if the extension is busy, the caller must pay for the connection because of the ANSWER().
