Thank you for your piece of dialplan but i don't think it's the  
solution. You offer a different solution to set the nibble_rate  
variable, but in my sample case this variable is properly set because  
the call is billed.

A bug, maybe. I don't remember my freeswitch version ( i can't connect  
to my servers yet ) but i think it's 1.4 series.

I can try the last 1.6 version, i will also try a standard freeswitch  
sample configuration ( without config files provided by fusionpbx )
