It definitely isn't Diameter CCA -- that is a protocol used internally within 
the network for exchanging charging messages.  It is probably USSD 
notification (although it could also be Flash SMS).  I haven't tested either 
with the N900 but my guess is that Flash SMS should work but USSD 
notification probably doesn't (I wonder if that will be included in the PR1.2 
fixes?).

Which network?  Which circle?
