In Sweden and most countries with EuroISDN the riginating switch will 
_not_ provide the progress tones to the caller, that is done by the remote 
switch / end pbx. Of course, this is only done if the pbx at the end 
signals that in band progress information is available.

It is of coursepossible that BT is more prohibitive. They are a bit weird 
when it comes to isdn.
