Can you get some more info why your PBX claims that "message not compatible 
with call state ...." in the following STATUS message:

Also try setting a manual TEI value, by using the "-i " option when 
running "isdnconfig". See "man isdnconfig" for more info. Eg:

isdnconfig -u 9 -i 3 -p DRVR_DSS1_TE

If the command fails, you just have to upgrade I4B, hence the "-i" option was 
not functional in the code for some time.
