Okay, lets have a look at the first case:
...
-- ISDN2: Error setting up echo canceller (PLCI=0x102)
Dec 22 11:53:50 WARNING[3056647088]: chan_capi.c:3270 show_capi_conf_error:
ISDN2: conf_error 0x300b PLCI=0x102
Command=FACILITY_CON
F,0x8497
> CAPI INFO 0x300b: Facility not supported
...
when a connection is established the echo-cancel will be activated. But in
this case the driver rejects this. Maybe the card does not support it, or
the wrong facility-selector is used (for older eicon driver you must set
echocancelold=yes).
Anyway, this is just a warning and the call goes on....
...
Dec 22 11:53:51 ERROR[3052743600]: chan_capi.c:1173 capi_write: dont know
how to write subclass 64
...
Now this is the problem why the call is disconnected. It is exactly the
problem I described: openpbx tries to send subclass 64 voice (slin) to
capi which supports alaw only !
Now the second case:
...

I cannot find any error in this log. It looks like a perfect connection
(except the echo-cancel warning again). The call is connected and then just
hung up with cause 'normal call clearing'.
