1) No
2) Depends. In some ISDN networks you can pay for an additional feature
"CLI not screened" or similar, which means the number sent will not be
"corrected" by the telco switching equipment if an "invalid" number is
sent. AFAIK standard ISDN lines do not allow to send a number that is
not connected to the line in question.
3) AFAIK same for ISDN PRIs.
4) Depends. Some allow sending any number, some always send "your"
number and do not even allow to bar the number.

sipgate.de for example allow to send any German regular number (or any
number that looks like a valid number), but blocks special (0800, 0900,
112) numbers.
