Thanks. This would help in part. Yet I'll probably forbid outside 
transfers and allow only transfers to a predefined number list.
That way I know what's going on.
In the mean time, I had a look at how transfers are handled by the
alcatel 4400 pbx at work; looks like it's the same.
If A calls B who then transfers to C it is reported as A calls C aka 
extern->extern.
It seems so strange to me that I started to wonder if transfers would 
not just be signaling instead of a call.
Yet I doubt that because forbiding outgoing calls, prevented me from
making the transfer. Besides, signaling should be possible w/ digital
lines but how whould that be done with analog PSTN?
