Sounds like a case for either  (1)  a different context per originating 
extension  (or maybe, per group of originating extensions which all happen to 
obey the same mathematical formula for determining outside callerID from 
inside extension number);  (2)  an AGI script, accessing a database which 
links internal extensions to external numbers; or  (3)  rethinking your 
internal extension numbering scheme so there is a consistent mapping from 
internal to external numbers, thus allowing you to do it all mathematically.
