Hmmm BTN, may be I should tell that to my E1 provider, they use my 
CallerID as the BTN, additionnaly whenever I don't provide a number 
which matches the one configured on my PRI the set a default CallerID!!! 
So that's also the reason why they cannot provide me with such a service 
like send-any-callerid-you-like!!! Too bad!!!
