Thats not correct.  The call will come in with whatever the user 
dialed.  If he dialed XXX1900 then you will see 1900.  If he dialed 
XXX3570 then you will see 3570.  If you want to handle multiple callers 
simultaneously dialing the same number then setup a queue or handle them 
which ever way you prefer.
