Thanks Brian,

probably i should have explained it in more details.
this whole thing started as an attempt to  implement lata ocn /local 
number portability/ instead of  pure per destination routing.
At the moment i have a access to  a service provider  who does 
"dipping"  and returns  the  LATA OCN  data associated with  any dialed 
destination number. it is returned as Contact:  and Content-length:  
fields in 302 message.

in other words:

1. i'm sending to this provider let say - 2025556666  as a destination 
number.
2. they do the dipping  and will return to me  either the new dest #  if 
2025556666 has been ported or if it was not
in content-length field they'll send  lata, ocn  and state and 10 digits 
number.
3. once received i have to  compare the received lata , ocn and state  
date with  a compiled  rate deck / blended from 5 different vendors/  
and pick the lowest rate - effectively building  LCR based on LATA OCN 
STATE info.

Hope this will help to clear the picture.

Chav
