asterisk users - Mar 2004 - Transfer and Native Bridge unwanted - was Native Bridge and Billing

Hi all,

Ok. Now I know I can't bill a call when I have a "native bridge" 
betweens *. And I do not want a "Native Bridge". How could I disable 
"native bridge"? I tried "notransfer=yes" but connection
tries to start
a native bridge and then closes.
