Call redirection service processor in Telecom

A single instance of call redirection processor that handles the call
redirection with user-defined CallRedirectionService and carrier

A user-defined call redirection will be performed firstly and a carrier
call redirection will be performed after that; there will be a total of
two call redirection cycles.
