First, I suppose calling it "channels" to begin with was a bad idea,  
as it is the root cause of the confusion.  "channels" in this context,  
or in the case of "sip show channels", is different than the Asterisk  
channel concept.  These CLI commands show all exchanges currently in  
progress at the protocol level.

So, with that said, we should definitely leave these types of entries  
in the output.  To clarify their meaning, how about we add a new  
column to the output that indicates what type of IAX2 message started  
this dialog? (Do we call them dialogs in IAX2?)  So, it would say NEW,  
POKE, REGREQ, etc.  I also like the "Last Message" item in the  
chan_sip output.
