I think that passing an unique identifier when an IAX box "switches" the call 
to another one by transfer could possibly phave some other advantages than 
cdr only, expecially if they are remote.

It will need, of course, some IAX configuration parameter saying that that 
trusted iax user/friend is allowed to override the accountcode. I like the 
@<switch> idea.

And probebly keeping some state information for already transferred and 
terminated calls, and delay the cdr record until some "call termination" 
message comes (what happens if that never comes?)

It would, however, get rid of the nonsense cdr recording on the "switch" of a 
billable call with 11 or 12 billable_seconds which are duplicate accounted on 
the "gateway".

thanks for your help,
