[Serusers] accounting fifo messages

[SER Users]

hello,

I am trying to force a call disconnect by sending a BYE to both ends. 
everything is ok, the call gets disconnected but I do not manage to get 
the BYE message accounted by the accounting module.
Is it possible to do accounting on messages sent using the fifo 
interface, is it something special that needs to be configured ?

thanks,
Razvan Radu
