I don't recall if -<session> is a fixe number of digits.  If so, you 
can use the string manipulation features within Asterisk to cut it 
off.  I don't have the manual reference right here with me, but note 
that you can put negative numbers for ${EXTEN:-1:-3} and the like, 
which will chop things up based on fixed positions within the string.
