Diego,

I understand now what u mean. If there is no account balance, the radius does not authorize the call.
However, the reason I have written it in this way was that there are software not able to process additional avps received from Radius server, therefore I had to make sure that if there is no balance, there will be no call authorized (any limited proxy will deny the call automatically if radius returns unauthorized).

I have a mechanism working without this standard behavior, so will consider introducing it into next releases as optional.

Cheers,
DanB
