Kannel Parsing access/global #

hi ive been reading the manual for quite sometime and upto now i havent got 
the answer...

assuming a telco gave us an access numbers with a unique prefix (lets say 123) 
so all sms message sent to 1234,1235,123001,123111 will be thrown to one 
server...  is it possible to parse the suffix of those numbers... and route 
per suffix on a sms-service?


hmm .. and also assuming the telco allowed us to fake the sender... by placing 
a value on "from" form variable in the sms push

TIA
