Yeah, I was digging through this to try to tease out some of the inner 
workings of the protocol.

One thing I did notice, and was curious about.  A mini-frame only has 
the sender conversation number.  This is used to as in index for the 
connection in iaxs[].  Since this is assigned by the sender and not the 
receiver, isn't it possible for there to be a collision?  I would think 
that only the combination of scallno:dcallno would be guaranteed to be 
unique.

Or am I missing something really simple?
