Hi ..I want to do something like this: When someone calls me at three  
numbers ( for example 300800901 and 300800902 and 300800903 ) I want to  
direct those calls to a single number ( for example 300800900 ).
And nother problem: if someone calls 300800910 and the number is busy then  
I want to direct him to 300800911 or 300800912 and if these two last  
numbers are busy too then I want him to be directed to 2222222 (for  
example).
