Indeed (why would one want to do this?).

Of course, the interesting thing with starting a new CID for a new  
call that immediately follows a preceding call is that you are then  
stuck with that (non-zero) CID for the duration of that flow (or  
until you IR context CID=0 with the same flow, which also is a bit  
inefficient).  CR would help a bit here (but the CR packets still  
aren't second order).

All quality of implementation issues, nothing to standardize here.
(Except that the full-byte penalty for CID≠0 is somewhat unfortunate,  
but we didn't have a way to come up with a smaller penalty.)

Gruesse, Carsten
